UPSC CSE Prelims Paper 2 Practice Test - 2 - Question 2

Present ages of Rajeev and Anand are in the ratio of 7: 10 respectively. Five years hence, the ratio of their ages will become 8: 11 respectively. If the Sum of the present age of Rajeev and Anand is ab. then, find what the unit digit of (ab) is?

Detailed Solution for UPSC CSE Prelims Paper 2 Practice Test - 2 - Question 2

Let the present ages of Rajeev and Anand be 7x and 10x years respectively.

Then,

⇒ 77x + 55 = 80x + 40

⇒ 3x = 15

⇒ x = 5

So, the present ages of Rajeev and Anand are (7 x 5)and (10 x 5) respectively.

The sum of their ages = (35 + 50) = 85 Hence, a = 8 and b = 5

Then, ab = 85

We know unit digit of 8 repeated after 4 powers. So, unit digit of 85 = unit digit of 81 ⇒ 8

UPSC CSE Prelims Paper 2 Practice Test - 2 - Question 4

One-way governments can decrease air pollution is to impose a tax on industrial carbon dioxide emissions. But why should governments consider a carbon tax when they could control emissions by establishing energy efficiency and conservation standards, by legislating against coal use, or by increasing investment in nuclear? The great virtue of such a tax is that it would provide incentives for industry to achieve emission reductions. Because oil emits more carbon dioxide per unit of energy generated than does natural gas, and coal more than oil, a carbon tax would vary with the type of fuel. Such a tax would induce industry to substitute less-polluting fuels for those carrying a higher tax and also to reduce the total use of energy.

Q. Which one of the following circumstances would most seriously undermine the conclusion “Such a tax would induce industry to substitute less- polluting fuels for those carrying a higher tax”

Detailed Solution for UPSC CSE Prelims Paper 2 Practice Test - 2 - Question 4
From the passage it can be inferred that author mentioned that such a tax would induce industry to substitute less-polluting fuels for those carrying a higher tax because author thinks that the fuel taxed the highest costs considerably less to buy than fuel for those carrying higher tax.

UPSC CSE Prelims Paper 2 Practice Test - 2 - Question 5

"Popular art" has a number of meanings, impossible to define with any precision, which range from folklore to junk. The poles are clear enough, but the middle tends to blur. The Hollywood Western of the 1930‘s, for example, has elements of folklore, but is closer to junk than to high art or folk art. The case of Giuseppe Verdi is an interesting one: he took a popular genre, bourgeois melodrama set to music and, without altering its fundamental nature, transmuted it into high art. This remains one of the greatest achievements in music, and one that cannot be fully appreciated without recognizing the essential trashiness of the genre. As an example of such a transmutation, consider what Verdi made of the typical political elements of nineteenth-century opera. Generally, in the plots of these operas, a hero or heroine— usually portrayed only as an individual, unfettered by class—is caught between the immoral corruption of the aristocracy and the doctrinaire rigidity or secret greed of the leaders of the proletariat. Verdi transforms this naive and unlikely formulation with music of extraordinary energy and rhythmic vitality, music more subtle than it seems at first hearing. There are scenes and arias that still sound like calls to arms and were clearly understood as such when they were first performed. Such pieces lend an immediacy to the otherwise veiled political message of these operas and call up feelings beyond those of the opera itself. Or consider Verdi’s treatment of character. Before Verdi, there were rarely any characters at all in musical drama, only a series of situations which allowed the singers to express a series of emotional states. Any attempt to find coherent psychological portrayal in these operas is misplaced ingenuity. The only coherence was the singer’s vocal technique.

Q. According to the passage, the immediacy of the political message in Verdi’s operas stems from the

UPSC CSE Prelims Paper 2 Practice Test - 2 - Question 8

Although pathogenic organisms constantly alight on the skin, they find it a very unfavourable environment and, in the absence of injury, have great difficulty colonizing it. This "self-sterilizing" capacity of the skin results from the tendency of all well-developed ecosystems toward homeostasis, or the maintenance of the status quo. Species that typically live in

soil, water, and elsewhere rarely multiply on the skin. Undamaged skin is also unfavourable to most human pathogens. The skin is too acid and too arid for some species. The constant shedding of the surface skin layers further hinders the establishment of invaders. The most interesting defence mechanism, however, results from the metabolic activities of the resident flora. Unsaturated fatty acids, an important component of the lipids in sebum collected from the skin surface, inhibit the growth of several bacterial and fungal cutaneous pathogens. These acids are a metabolic product of certain gram-positive members of the cutaneous community, which break down the more complex lipids in freshly secreted sebum.

Q. The primary purpose of the passage is to

For some time, scientists have believed that cholesterol plays a major role in heart disease because people with familial hypercholesterolemia, a genetic defect, have six to eight times the normal level of cholesterol in their blood and they invariably develop heart disease. Scientists also noticed that people with familial hypercholesterolemia appear to produce more LDL’s (low-density lipoproteins) than normal individuals. However, scientists wondered, could a genetic mutation that causes a slowdown in the removal of LDL’s from the blood also result in an increase in the synthesis of this cholesterol-carrying protein? Since scientists could not experiment on human body tissue, their knowledge of familial hypercholesterolemia was severely limited. However, a breakthrough came in the laboratories of Yoshio Watanabe of Kobe University in Japan in 1980. Watanabe noticed that a male rabbit in his colony had ten times the normal concentration of cholesterol in its blood. By appropriate breeding, Watanabe obtained a strain of rabbits that had very high cholesterol levels. These rabbits spontaneously developed heart disease. To his surprise, Watanabe further found that the rabbits, like humans with familial hypercholesterolemia, lacked LDL receptors. What scientists learned by studying the Watanabe rabbits is that the removal of the VLDL (very low-density lipoproteins) remnant requires the LDL receptor. Normally, the majority of the VLDL remnants go to the liver where they bind to LDL receptors and are degraded. In the Watanabe rabbit, due to a lack of LDL receptors on liver cells, the VLDL remnants remain in the blood and are eventually converted to LDL’s. The LDL receptors thus have a dual effect in controlling LDL levels. They are necessary to prevent over synthesis of LDL’s from VLDL remnants and they are necessary for the normal removal of LDL’s from the blood.

Q. The passage supplies information to answer which of the following questions?

UPSC CSE Prelims Paper 2 Practice Test - 2 - Question 20

"I want to criticize the social system, and to show it at work, at its most intense." Virginia Woolf’s provocative statement about her intentions in writing Mrs. Dalloway has regularly been ignored by the critics, since it highlights an aspect of her literary interests very different from the traditional picture of the "poetic” novelist concerned with examining states of reverie and vision and with following the intricate pathways of individual consciousness. In her novels, Woolf is deeply engaged by the questions of how individuals are shaped (or

deformed) by their social environments, how historical forces impinge on people’s lives, how class, wealth, and gender help to determine people’s fates. Most of her novels are rooted in a realistically rendered social setting and in a precise historical time.Woolf’s focus on society has not been generally recognized because of her intense antipathy to propaganda in art. The pictures of reformers in her novels are usually satiric or sharply critical.Woolf detested what she called "preaching" in fiction, too, and criticized novelist D. H. Lawrence (among others) for working by this method. Woolf’s own social criticism is expressed in the language of observation rather than in direct commentary, since for her, fiction is a contemplative, not an active art. Woolf’s literary models were acute social observers like Chekhov and Chaucer. As she put it in The Common Reader, "It is safe to say that not a single law has been framed or one stone set upon another because of anything Chaucer said or wrote; and yet, as we read him, we are absorbing morality at every pore."

If 4+9= 18, 5+8=20 and 5+6 =15, then the value of 8+112=?

Detailed Solution for UPSC CSE Prelims Paper 2 Practice Test - 2 - Question 25

Let's look at the given operations and try to find a pattern:
4+9 = 18
5+8 = 20
5+6 = 15

It seems like the first number is being multiplied by the second number, and then the result is divided by 2:
(4 * 9) / 2 = 18
(5 * 8) / 2 = 20
(5 * 6) / 2 = 15

Now let's use the same pattern to find the value of 8+112:
(8 * 112) / 2 = 896 / 2 = 448
So, the value of 8+112 is 448 (option B).

Q. Hockey and Volleyball days have a gap of how many days between them?

Detailed Solution for UPSC CSE Prelims Paper 2 Practice Test - 2 - Question 27

Explanation:


 


  • Cricket is not played on the first or last day, so it must be played on Tuesday, Wednesday, Thursday, or Friday.

  • Cricket is played earlier than Tennis, so Cricket cannot be played on Friday.

  • Therefore, Cricket is played on Tuesday, Wednesday, or Thursday.

  • Volleyball is played on the immediate next day of the tennis day, so Volleyball is played on Wednesday or Thursday.

  • Hockey is played on the immediate previous day of the rest day, so Hockey is played on Monday or Friday.

  • Soccer is played on the day following the rest day, so Soccer is played on Sunday or Saturday.

  • Since Cricket is not played on the first day, Hockey must be played on Friday.

  • Therefore, the schedule is as follows:

    • Monday: Hockey

    • Tuesday: Cricket

    • Wednesday: Volleyball

    • Thursday: Tennis

    • Friday: Rest day

    • Saturday: Soccer


    •  

  • Therefore, Hockey and Volleyball days have a gap of 4 days between them.

  1. Aayush’s playing schedule consists of Cricket, Hockey, Soccer, Tennis, and Volleyball from Monday to Saturday; each game is on one day, one day being a rest day.

  2. Cricket is played neither on the first day nor on last day but is played earlier than Tennis.

    1. Volleyball and Soccer were played with a 2-day gap between them.

    2. Soccer is played on the day following the rest day.

Q. Which of the following is a correct statement?

Detailed Solution for UPSC CSE Prelims Paper 2 Practice Test - 2 - Question 29
The starting figure we start with when we read the first statement is

Games are hockey, tennis, cricket, volleyball, and soccer.

From the second and third clues (cricket is played neither on the first day nor on the last day but was played earlier than tennis, and volleyball was played on the day immediately following the tennis day), we know that tennis and volleyball should be together and also that cricket has to be somewhere before this.

Visually this can be represented as:

C ⇒ TV

From the fourth and sixth clues we have:

H-REST DAY’S

Note: Putting it in a box signifies that there is no break between the items in the box.

Once we have these two visual representations we can go back to our original figure and think as follows:

Since cricket has to precede tennis and volleyball, and cricket is not on the first day we can have three possibilities of placing cricket viz., Tuesday, Wednesday or Thursday

Possibility 1:

This case is rejected because once we place cricket we would need to place tennis and volleyball in either Wednesday-Thursday or Thursday-Friday or Friday-Saturday. In each case, we would also need to place a 3-day having Hockey-Rest Day-Soccer. It can be easily seen that in any of these three situations under possibility 1, we do not have a complete 3-day period anywhere in the week. Thus, we can reject possibility 1.

Possibility 2

Rejected on the same logic as possibility 1. There is no availability of a 3-day having Hockey-Rest Day-Soccer.

Possibility 3:

This is the only possibility that would work, as in this case, the respective game order

would be:

Bigotry and racism are among the deadliest social ills plaguing the world today, but, unlike a team of costumed super-villains, they can’t be halted with a punch in the snoot or a zap from a ray gun. The only way to destroy them is to expose them - to reveal them for the insidious evils they really are. The bigot is an unreasoning hater - one who hates blindly, fanatically,

indiscriminately. If his hang-up is black men, he hates ALL black men. If a redhead once offended him, he hates ALL redheads. If some foreigner beat him to a job, he’s down on ALL foreigners. He hates people he’s never seen - people he’s never known - with equality intensity - with equal venom. Now, we’re not trying to say it’s

unreasonable for one human being to bug another. But, although anyone has the right to dislike another individual, it’s totally irrational, patently insane to condemn an entire race - to despise an entire nation - to vilify an entire religion. Sooner or later, we must learn to judge each other on our own merits. Sooner or later, if man is ever to be worthy of his destiny, we must fill our hearts with tolerance. For then, and only then, will we be truly worthy of the concept that man was created in the image of God - a God who calls us ALL - His children. Pax et Justitia
