A study of business partnerships in which one partner’s management style differs from that of the other partner reveals that such partnerships are more likely be fraught with problems and to ultimately end in dissolution. Thus, mismatched management styles can seriously jeopardize a business partnership.
Q. Which of the following, if true, most seriously weakens the argument above?

Detailed Solution for GMAT Full Mock Test- 3 - Question 4

If partners who are considering dissolution have been found to express hostility by adopting a different management style from that of their partners, then the different management styles are the result and not the cause of the discordance between the partners.

A report on the use of monosodium glutamate in food concluded, “Most Americans who consume monosodium glutamate regularly are not being harmed.” Critics of the report insist the conclusion be changed to, “Most Americans who consume monosodium glutamate do not show visible symptoms of harm by the substance, such as abnormal rashes or slower rates of metabolism.”
Q. Which of the following, if true, provides the best logical justification for the critics’ insistence that the report’s conclusion be changed?

Detailed Solution for GMAT Full Mock Test- 3 - Question 5

If there is a possibility that monosodium glutamate will cause long-term harm, then the absence of symptoms cannot be taken as proof that Americans who consume monosodium glutamate regularly are not being harmed.

GMAT Full Mock Test- 3 - Question 6

On May 5th, 1997, the European edition of Business Tech Magazine led with Hoffman’s cover story "Internet Communities: How They're Shaping Electronic Commerce". This cover story highlights the extent to which the term virtual community has become almost synonymous with various forms of group-CMC (computer-mediated communication), including email-list forums, chat-systems such as IRC, web-based discussion areas and UseNet news-groups. There was no debate in the Business Tech Magazine article as to whether the group-CMC discussions are really 'communities', rather how the community, as opposed to content, can be used to encourage people to return to a particular part of cyberspace for commercial gain. In a similar vein, Simpson and Armstrong in "Internet Gain" argue that ignoring virtual communities would be a great loss of a marketing tool for businesses. They define virtual communities as computer-mediated space where there is an integration of content and communication with an emphasis on member-generated content. Not all virtual community commentators agree with the Spartan position taken by Hoffman. Rheingold, one of the prime popularizers of the term virtual community, provides us with a more emotive definition in his book The Virtual Community: Homesteading on the Electronic Frontier. According to Rheingold, "virtual communities are social aggregations that emerge from the Net when enough people carry on those public discussions long enough, with sufficient human feeling, to form webs of personal relationships in cyberspace". Rheingold's definition is extremely popular and has been quoted in many discussions about virtual communities. As discussed below, for social scientists, particularly sociologists, Rheingold's definition raises many issues, especially concerning the notion of community. This is because Rheingold argues via a variety of analogies from the real world such as homesteading that virtual communities are indeed new forms of "community". In fact, Rheingold implies that virtual communities are actually "a kind of ultimate flowering of a community". Moreover, Rheingold maintains that whenever computer-mediated communications technology becomes available; people inevitably create communities with it. Rheingold can thus be labeled as a technological determinist as he holds that there is a predictable relationship between technology and people's behavior. The debate over the validity of Rheingold's position has raised doubts about the existence of virtual communities and the appropriate use of the term. Weinreich claims that the idea of virtual communities must be wrong because the community is a collective of kinship networks that share a common geographic region, a common history, and a shared value system, usually rooted in a common religion. In other words, Weinreich rejects the existence of virtual communities because group-CMC discussions cannot possibly meet his definition. In Weinreich's view, anyone with even a basic knowledge of sociology understands that information exchange in no way constitutes a community.
Q. The primary purpose of the passage is to

Detailed Solution for GMAT Full Mock Test- 3 - Question 6

The passage begins by presenting the viewpoint of those that believe that group-CMCs are true communities and continues by presenting an opposing view. D is incorrect because definitions, not hypotheses are discussed in the passage.

Q. The author says ‘there was no debate in the Business Tech Magazine article’ to emphasize which of the following points?

Detailed Solution for GMAT Full Mock Test- 3 - Question 9

The passage discusses whether group-CMCs are communities. Business Tech Magazine does not debate this issue because it has already assumed that they are.

Until recently, most automobile manufacturers minimized the weight of their cars to maximize mileage. The safest chassis were heavy, so few manufacturers equipped their cars with the safest chassis. This year the chassis metal that has sold best to automobile manufacturers has been the safest one—a clear indication that manufacturers are assigning a higher priority to safety than to mileage.

GMAT Full Mock Test- 3 - Question 13

Until recently, most automobile manufacturers minimized the weight of their cars to maximize mileage. The safest chassis were heavy, so few manufacturers equipped their cars with the safest chassis. This year the chassis metal that has sold best to automobile manufacturers has been the safest one-a clear indication that manufacturers are assigning a higher priority to safety than to mileage.

Which of the following, if true, most seriously weakens the argument above?

Detailed Solution for GMAT Full Mock Test- 3 - Question 13

The conclusion is based on an assumption that the safest chassis are still the heaviest ones, as they have been in the past. Choice E proves this assumption to be erroneous.
The CEO of Black’s International has proposed replacing their Marmacil semiconductor manufacturing equipment with Fasttech equipment since it costs 30 percent less to train new staff on the Fasttech equipment. Those opposed to the change have pointed out the savings in training cost does not justify the change. Instead, they suggested that the company hire only people who already know how to use the Marmacil equipment.

GMAT Full Mock Test- 3 - Question 14

Which of the following, if true, most seriously undermines the objection to the replacement of Marmacil semiconductor manufacturing equipment with Fasttechs?

Which of the following, if true, most seriously undermines the objection to the replacement of Marmacil semiconductor manufacturing equipment with Fasttechs?

Detailed Solution for GMAT Full Mock Test- 3 - Question 14

Those objecting to the change claim that the advantage of Fasttech’s relatively low cost can be mitigated by hiring experience users of Marmacil semiconductor manufacturing equipment. However, if such people command much higher salaries as choice C states, doing so would not result in savings to the company.

GMAT Full Mock Test- 3 - Question 15

A pharmaceutical company developed a new diuretic reported to cause fewer side effects than their old diuretic, which was still being manufactured. During the first year that both were sold, the earlier medication far outsold the new one; the manufacturer thus concluded that reducing side effects was not the customers' primary consideration.
Q. Which of the following, if true, would most seriously weaken the manufacturer’s conclusion?

Detailed Solution for GMAT Full Mock Test- 3 - Question 15

The manufacture’s conclusion was that reducing side effects was not the customers' primary consideration. Choice B states that customers consider older medication a better safety risk, so those customers bought the older diuretic out of safety considerations.

GMAT Full Mock Test- 3 - Question 17

Take a very commonplace, often discussed and critical topic: Are we detecting a greenhouse effect, and related to this, is it exacerbated by "homogenic factors," i.e., human actions? Most would be inclined to give a positive answer to both of these questions. But, if pushed, what would be the evidence, and how well grounded would it be for such affirmations? Within scientific communities and associated scientifically informed circles, the answers have to be somewhat more ambiguous, particularly when rigorous questions concerning evidence are raised. Were scientific truth to be a matter of consensus, and some argue that scientific truth often turns out to be just that, then it is clear that there is beginning to be a kind of majority consensus among many earth science practitioners that the temperature of the Earth, particularly of the oceans, is indeed rising and that this is a crucial indicator for a possible greenhouse effect. Most of these scientists admit that the mean oceanic temperature has risen globally in the last several decades. But this generalization depends upon how accurate measurements may be, not just for samples, but also for the whole Earth. Hot spots, for example the now four year old hot spot near New Guinea which is part of the El Niño cycle, does not count by itself because it might be balanced by cold spots elsewhere. And the fact of the matter is that "whole earth measurements" are still rare and primitive in the simple sense that we simply do not have enough thermometers out. Secondly, even if we had enough thermometers, a simply synchronic whole earth measurement over three decades is but a blip in the diachronic history of ice age cycles over the last tens of thousands of years. Thirdly, even if we know that the earth is now heating up, has an ever increasing ozone hole, and from this strange weather effects can be predicted, how much of this is due to homorganic factors, such as CFCs, CO2 increases, hydrocarbon burning, and the like? Is it really the case, as Science magazine claimed in l990, "24% of greenhouse encouraging gases are of homorganic origin"?
Q. In this passage the author is primarily interested in

Detailed Solution for GMAT Full Mock Test- 3 - Question 17

The author questions the claim that there is indeed a greenhouse effect that is made worse by human actions. (A) is too general an answer, while (D) is too specific. (D) is wrong because it is probing whether scientists agree, not whether there the phenomenon actually exists.

Q. The author of the passage would be most likely to agree with which of the following statements about the greenhouse effect?

Detailed Solution for GMAT Full Mock Test- 3 - Question 18

Scientists are basing their claims on global warning on rising ocean temperatures. One can tell if temperatures have in fact risen only by measuring them correctly.

Q. It can be inferred from the passage that

Detailed Solution for GMAT Full Mock Test- 3 - Question 19

The author is questioning the cause and effect relationship between the increasingly large ozone hole and global warming, as well as cause and effect relationship between global warming and strange weather effects.

Q. The explanation offered above for the low esteem in which marine biologists who make documentary films are held by research scientists assumes that

Detailed Solution for GMAT Full Mock Test- 3 - Question 28

The conclusion that biologists who make documentaries should no longer be regarded as true colleagues is based on the assumption that such biologists will not longer do important new research

GMAT Full Mock Test- 3 - Question 29

An Australian group named Action Council on Smoking and Health (ACSH) has recently lobbied to make warnings on cigarette packets more graphic. The council proposed that striking visual photos of diseased organs should be put on at least 50% of outside packaging, in conjunction with health warnings outlining smoking hazards enumerated in a separate leaflet placed inside the cigarette packet. The ACSH claim that bland and ineffectual warnings like "Smoking is a health hazard" currently found on cigarette packets are not nearly sufficient. Substituting those inadequate admonitions with explicit photos will provide a powerful visual stimulus to help smokers relinquish their habit. The current cautions on cigarette packets have little or no impact on smokers who have grown immune to the warnings that focus on abstract tobacco related risks and illnesses from which smokers can easily disassociate themselves. The proposed new tactics would concentrate on the perspective of the individual smoker through a demonstration of what is occurring in his body each time he reaches for a cigarette, rather than a generic cautionary word of advice.
The ACSH cited the results of recent studies conducted by psychologists at McKean University confirming that evidence related to one's own experience is more effective at influencing future behavior than a presentation of facts and figures.

Q. It can be inferred from the passage

Detailed Solution for GMAT Full Mock Test- 3 - Question 29

We do not have information about (A) (B) and (D) from the passage. (E) is incorrect because the passage claims that smokers have an opportunity to look at their cigarette packages, not that they actually do.

GMAT Full Mock Test- 3 - Question 30

An Australian group named Action Council on Smoking and Health (ACSH) has recently lobbied to make warnings on cigarette packets more graphic. The council proposed that striking visual photos of diseased organs should be put on at least 50% of outside packaging, in conjunction with health warnings outlining smoking hazards enumerated in a separate leaflet placed inside the cigarette packet. The ACSH claim that bland and ineffectual warnings like "Smoking is a health hazard" currently found on cigarette packets are not nearly sufficient. Substituting those inadequate admonitions with explicit photos will provide a powerful visual stimulus to help smokers relinquish their habit. The current cautions on cigarette packets have little or no impact on smokers who have grown immune to the warnings that focus on abstract tobacco related risks and illnesses from which smokers can easily disassociate themselves. The proposed new tactics would concentrate on the perspective of the individual smoker through a demonstration of what is occurring in his body each time he reaches for a cigarette, rather than a generic cautionary word of advice.

Statement (1) tells us that 10 cans cost 4.2 dollars instead of 5 dollars and therefore the last two cans were sold for 20 cents. This  Statement is sufficient. Statement (2) also tells us that the entire amount of cans cost 4.2 and  therefore this statement is also
sufficient.

GMAT Full Mock Test- 3 - Question 72

Does the product of XYZW = 16?
(1) Y = 1.
(2) X = 4Y and ZW = 4Y2

Detailed Solution for GMAT Full Mock Test- 3 - Question 72

From (1) we know the value of Y only, which is 1. From (2) and (1) we know the value of all the other parameters, X = 4 and ZW = 4. Therefore, (1) and (2), together are sufficient.

GMAT Full Mock Test- 3 - Question 73

The telephone company wants to add an area code composed of 2 letters to every phone number. In order to do so, the company chose a special sign language containing 124 different signs. If the company used 122 of the signs fully and two remained unused, how many additional area codes can be created if the company uses all 124 signs?

Detailed Solution for GMAT Full Mock Test- 3 - Question 73

The phone company already created 122*122 area codes, now it can create 124*124. 1242-1222=(124+122)(124-122) = 246*2 = 492 additional codes.

GMAT Full Mock Test- 3 - Question 74

The average (arithmetic mean) of seven numbers is 12.2. If the sum of four of these numbers is 42.8, what is the average of the other 3 numbers?

Detailed Solution for GMAT Full Mock Test- 3 - Question 74

If the average of 7 numbers is 12.2, we can solve for their sum: 7 × 12.2 = 85.4. If four of these numbers total 42.8, then by subtracting 42.8 from 85.4, we get the sum of the other three numbers, 42.6. To find the average of these three numbers, we divide their sum by their number: 42.6/3 = 14.2.

GMAT Full Mock Test- 3 - Question 75

If A = 2B, is A4 > B4?
(1) A2 = 4B2.
(2) 2A + B < A/2 + B.

Detailed Solution for GMAT Full Mock Test- 3 - Question 75

Statement (1) is insufficient. Take A=0 and B=0, (1) is correct yet A4 is not bigger than B4.Take different numbers, A=6 and B=12 A4 is larger than B4.Statement (2) is sufficient. The only possible way that A will not be larger than B is if they are both zero. (2) Claims that A < 0 and therefore A cannot be zero and this statement is sufficient, A4 is bigger than B4.

GMAT Full Mock Test- 3 - Question 76

5 numbers are randomly chosen. If their average is 20, how many of the numbers are larger than 15? (1) One of the numbers is 15.
(2) The average of three of the numbers is 15.

Detailed Solution for GMAT Full Mock Test- 3 - Question 76

Lets look at two cases, where each one will give outdifferent results .One of the numbers is 15 and three more are 15, 15 and 15 (with an average of 15).The sum of all the numbers should be (20 x 5 = 100). The sum of the numbers we picked up is (15 x 4 = 60) and therefore the last number should be 40 which is greater than 15. The answer in this case is 1.Take another case: One of the numbers is 15 and three more are 14, 15 and 16 (with an average of 15). In this case there will be 2 numbers over 15. More data is required.

GMAT Full Mock Test- 3 - Question 77

A drawer holds 4 red hats and 4 blue hats. What is the probability of getting exactly three red hats or exactly three blue hats when taking out 4 hats randomly out of the drawer and immediately returning every hat to the drawer before taking out the next?

Detailed Solution for GMAT Full Mock Test- 3 - Question 77

Getting three red out of 4 that are taken out has 4 options (4!/(3!*1!)) each option has a probability of (1/2)4 since drawing a red or blue has a 50% chance. 4*1/16= ¼ to get three red hats. The same goes for three blue hats so ¼+¼ =1/2.

GMAT Full Mock Test- 3 - Question 78

If 4XZ + YW = 3 and XW + YZ = 6, what is the value of the expression (2X + Y)(2Z + W)?

Detailed Solution for GMAT Full Mock Test- 3 - Question 78

(2X + Y)(2Z + W) = 4XZ + 2XW + 2ZY + WY. No , plug in this data to get: 3 + 2 x 6 = 15.

GMAT Full Mock Test- 3 - Question 79



Q: The change in the overall earnings for non-farming jobs plus small businesses between 2000 and 2010

Detailed Solution for GMAT Full Mock Test- 3 - Question 79

The correct answer choice is the fourth one - cannot be determined. Don’t be tricked into just adding up the percentages. The charts give the relative portions of the rural economy made up by these 4 items, but nowhere are we told absolute amounts - what was the overall size of the economy in 2000 and in 2010? This is necessary to then calculate the overall earnings in these particular areas in 2000 versus in 2010. Since we don’t know in which year the overall economy was larger, or if they were the same, we cannot make this comparison.

GMAT Full Mock Test- 3 - Question 80



Q: The smallest proportional change in percent between 2000 and 2010 in any segment of the rural economy was in

Detailed Solution for GMAT Full Mock Test- 3 - Question 80

The charts give %s of the rural economy. This question asks about percent change in those percentages. The % of the economy taken up by small businesses nearly doubled in these 10 years, for a percent change of nearly 100%. The % of the economy taken up by remittances increased by nearly 6x in these 10 years, for a percent change of around 467%. 

So we can quickly eliminate those two. But agriculture and non-farming jobs both decreased by proportionally similar amounts. Which experienced the smaller percent change? Non-farming jobs decreased by 6/24, or 25%. Agriculture decreased by 20/60, or 1/3, or 33%. 

Put in these terms, clearly non-farming jobs experienced a smaller % change than non-farming jobs, since 25% is less than 33%. Select the second option: non-farming jobs.

GMAT Full Mock Test- 3 - Question 81


Assuming the trend in the graph stays the same over the range of workers per supervisor values, if the company were to employ 20 workers per supervisor they would likely be __________ productive than if the company were to employ 160 workers per supervisor.

Detailed Solution for GMAT Full Mock Test- 3 - Question 81

Taking a close look at our curve, we can see that it’s not exactly a bell-curve (with equal rates of decline on either side of the peak) - the rise on the left hand side of the curve is slower than the decline on the right-hand side of the curve. The peak takes place around 100 workers per supervisor, yet 40 workers per supervisor (60 away from the peak value) are just about equally productive as 140 workers per supervisor (40 away from the peak value). If we were to extend a line on the left side of the graph, we will find that at about 30 workers per supervisor, per worker daily production is zero. If we were to extend the trend on the right side of the graph, we will find that at about 155 workers per supervisor,per worker daily production is zero. This suggests that at 160 workers per supervisor, per worker daily production will be negative. Therefore, the company will likely be more productive at 20 workers per supervisor than at 160 workers per supervisor. Choose (B). 

Note that extrapolating beyond the range of the data is generally not a good idea and could lead to some nonsensical conclusions. However, since you were asked to assume that the trend stays the same over the range of workers per supervisor values, we can infer that the company will be more productive at 30 workers per supervisor than at 160 workers per supervisor.

GMAT Full Mock Test- 3 - Question 82


If it wanted to increase productivity, a company currently employing 115 workers per supervisor should consider

Detailed Solution for GMAT Full Mock Test- 3 - Question 82

At 115 workers per supervisor, we are on the sloping down side of the curve, suggesting that we need to have slightly fewer workers per supervisor. The question asks about which option would increase productivity (not necessarily maximize it, just increase it), and since only one option can be right, it must be that three of the options will not increase productivity and only one will. 

First option - Adding more workers will mean moving to the right on the curve - more workers per supervisor - which clearly has lower productivity. 

Second option - halving the number of supervisors would mean doubling the number of workers per supervisor, to 230, and as per the trend of the graph, this would presumably have lower productivity. 

Third option - doubling the number of supervisors would mean that the ratio of workers to supervisor would be halved, to around 57.5 workers per supervisor, which has a lower productivity rate than 115 workers per supervisor. 

Fourth option - with 25% fewer workers, the company would have around 87 workers per supervisor. Looking at the curve, although the difference is not huge, this is clearly a more productive ratio than 115 workers per supervisor. Select this final option.

GMAT Full Mock Test- 3 - Question 83


The above graph gives the values for 4 items measured by the police department. One represents the number of crimes reported, one represents the number of arrests made, one represents the number of police officers on staff, and one represents the budget surplus for the department (in $1000s).

Q. If the impact of a change enacted by the police department takes a month to register, then we can identify a negative linear relationship between B and

Detailed Solution for GMAT Full Mock Test- 3 - Question 83

If there is a negative linear relationship, that means that when one variable goes up, the other goes down, and vice versa. The new wrinkle introduced by this question is that there can be a one-month lag in seeing this effect. B and D are opposites - when one goes up, the other goes down. If we were to introduce a one-month lag then it’s possible they could correlate directly, not indirectly. With a one-month lag, B and A now seems to be have a negative relationship - when one goes up, the other goes down the following month, and vice versa. But is it a linear relationship - can it be expressed in the form A = mB +c, for some constant values m and c, given a month’s lagtime? You don’t have to do the math, just look at the graph - in the first month, B went up a lot, and in the second month, A went down a little. In the second month, B went down a little, yet in the third month A went up a lot. This is inconsistent - if there’s a linear relationship, then the relative sizes of the changes need to be consistent with each other. Even if you look at the lag in the reverse direction, you’ll notice this same inconsistency. 

At this point, you could mark C by process of elimination, but let’s just make sure it works. C shows a decrease in the first 2 months, while B constantly alternates between increases and decreases. So let C lag one month behind B. Between March and April, B has a big increase, and between April and May, C has a relatively large decrease. Between April and May, B has a smaller decrease, and between May and June, C has a smaller increase. Between May and June, B has an increase larger than the decrease but not as large as the first increase, and between June and July, C has a decrease larger than the previous increase but not as large as the first decrease. C is the correct option.

GMAT Full Mock Test- 3 - Question 84

Article 1

News article in an environmental publication.

July 19 – If current trends continue, fossil fuels will be exhausted by 2052. Industry and transportation and the inability of governments to put stricter emissions regulations in place means that there will be a greater demand for alternative energy sources. Additionally, recent concerns about the high-cost of implementing new systems such as public transportation in industrialized areas has led many voters to actually strike down propositions to subsidize alternative fuel research.
 

Article 2

Interview with a well-known scientist.

August 3 – Dr. Lisa Goodman, one of the team of architects behind several new battery-operated commercial vehicles, has criticized the government’s unwillingness to aggressively lobby voters to pass measures to reduce fossil fuel usage. She suggests that without a significant reduction in per-person fossil fuel consumption, the rate of global warming could soon increase threefold.

“I know that voters continue to reject costly measures to reduce widespread fossil fuel consumption such as large-scale public transportation projects, and that politicians are naturally going to avoid stumping for unpopular policies. However, if something isn’t done soon, by 2055, a barrel of gasoline may become a luxury that only the rich can afford.”

 

Article 3

Article from a weekly news magazine.

August 29 – The price of crude oil has jumped by 500% over the last decade as a decrease in supply has met with an increased demand. This demand has encouraged many new oil wells to launch in the Gulf of Mexico, and some American environmental groups have expressed concern that certain oil companies are not following the safest procedures, emphasizing that the companies are more concerned with the speed of extraction than the well-being of the ecosystem. Some scientists in the Gulf have called for an increase in safety regulations for oil companies drilling off the coast, but the companies warn that this may dramatically increase the cost of crude oil, at a time when many Americans are already struggling to pay the increased price.

Consider each of the following statements. Does the information in the three articles support the inference as stated?

Q. 
Politicians usually do not agree with one another on issues of global warming and fossil fuel consumption.

Detailed Solution for GMAT Full Mock Test- 3 - Question 84

The answer is No. The statement in question is not necessarily true, as we do not know what politicians “usually’ do, and therefore this is not a valid conclusion just based on the information provided.

Q. 
An increase in worldwide demand for crude oil has made the oil companies' safety standards fall.

Detailed Solution for GMAT Full Mock Test- 3 - Question 85

The answer is No. In article 3, we are told that “environmental groups have expressed concern that certain oil companies are not following the safest procedures, emphasizing that the companies are more concerned with the speed of extraction than the well-being of the ecosystem.” However, if some oil companies are not following the safest procedures, we cannot infer that safety standards have fallen among oil companies due to the increase in worldwide demand. Perhaps those oil companies are choosing not to follow the safest procedures for other reasons.

Q. 
Dr. Goodman would likely support a public referendum on whether to require the oil companies to have better safety and ecological regulations.

Detailed Solution for GMAT Full Mock Test- 3 - Question 86

The answer is No. In Article 2, Dr. Goodman is shown to have little faith in the public as the solution to the global warming issue, since the public has continually shot down measures it considered “costly.” Dr. Goodman is primarily interested in seeing a reduction in fossil fuel usage. However, we cannot infer based on the information in the article alone that she would also be interested or not interested in requiring oil companies to have better safety and ecological regulations.
