## Five years ago, the town of Bayside, in the Katonic River Valley, had catastrophic flooding one spring, and consequently, most insurers now refuse to write flood insurance for houses in Bayside. The town of Dryadia, in the Phemptic River Valley, is much like Bayside in its proximity to a similar river at an almost identical point in the river valley. We can conclude that the only reason the same insurers do not write flood insurance for houses in Dryadia either is its similarity to Bayside in terms of where it is situated in the river valley.Q. Which of the following, if true, would most seriously undermine the argument?... more

Undermining the Argument:

Option D:
- This option states that the town of Dryadia experiences some flooding most springs.

## Wine Company Representative: The corks of red wine bottles pose a threat to the environment because they are treated with chemicals that are especially toxic in landfills. However, the new cork that our company developed, which will be adopted by the entire red wine industry, represents a solution. Since the new cork is natural and not treated with chemicals, when the industry completes its transition to the new cork, there will no longer be any threat to landfills from red wine corks.Q. Which of the following, if true, most weakens the argument above?... more

Weakness in the Argument:

After the industry's transition to new corks, a large number of wine bottles with old corks will continue to be consumed.

## In the twentieth century, the visual arts have embarked on major experimentation, from cubism to expressionism.  While tastes always vary, there are certainly some people who find beautiful objects of each of the art movements of the first half of the twentieth century.  In the latter half of the twentieth century, though, most works are so abstract or shocking that neither the critic nor the general public uses the word "beautiful" to describe them: indeed, sometimes late twentieth-century artists have, as one of their expressed goals, the creation of a work that no one could find beautiful.  Whatever these artists are creating may be intellectually engaging at some level, but it is no longer art.Q. Which of the following is an assumption that supports drawing the conclusion above from the reasons given for that conclusion?... more

Assumption Explanation:

Beauty is a defining quality of art:
- The assumption that beauty is a defining quality of art supports the conclusion that late twentieth-century works that are not considered beautiful are not art.
- If beauty is considered a defining quality of art, then works that do not possess this quality may not be classified as art.

## When, on a particular shopping trip, a consumer purchases an item which he previously had no intention of purchasing, this sale is called an “impulse purchase.” The objects of impulse purchases are occasionally essential items (i.e. items that satisfy basic subsistence needs), but much more frequently are luxury or non-essential items. Researchers have determined that, at the end of a shopping trip, a consumer is much more excited if she has bought a luxury item on an impulse purchase, than if she had made no impulse purchases.Q. If the information above is true, and if the researchers’ investigation was properly conducted, then which of the following must also be true?... more

Explanation:

- The researchers' conclusion is based on the premise that consumers are more excited when they make impulse purchases of luxury items.
- To properly assess this, the researchers must have had a reliable way to determine whether the consumer had initially planned to buy

## Every time a business grants financial credit to an individual, the business assumes risk. In order to evaluate the risk, a business must have correct information about that individual’s financial history. It is true that credit bureaus, which compile such information from computerized records, have been accused of invading the consumer’s right to privacy. If, however, only limited restrictions are placed on the availability of such information to businesses, those businesses will be able to reduce their overall exposure to risk by giving credit only to people with good credit ratings while at the same time extending larger amounts of credit to more people.

## If the area of a certain circle is x then the circumfernce is equal to?

 Prateek Gupta answered  •  2 days ago

Calculation of Circumference of a Circle

Area of the Circle:

• Let's assume the area of the circle is represented by x.

• The formula to calculate the area of a circle is A = πr^2, where A is the area and r is the radius of the circle.

• So, x = πr^2

Finding the Circumference:

• The formula to calculate the circumference of a circle is C = 2πr, where C is the circumference and r is the radius of the circle.

• We know that the area of the circle is x, so we can rearrange the formula for the area to find the radius: r = √(x/π).

• Substitute the radius into the formula for the circumference: C = 2π(√(x/π))

• Simplify the equation to get the circumference in terms of x: C = 2√(πx)

Conclusion:

• Therefore, if the area of a certain circle is x, then the circumference is equal to 2√(πx).

Can you explain this answer?

 Niti Choudhury answered  •  4 days ago
Analysis

Statement 1:

Increased Area with Increased Length

- Let the original length be L and width be W.
- The original area = L * W.
- The new length = L + 10 and new area = (L + 10) * W.
- Given that the new area is 100 sq. m more than the original area.

Statement 2:

Changes in Dimensions affecting Perimeter

- Let the original length be L and width be W.
- The new length = 1.1L and the new width = 0.9W.
- The new perimeter = 2(1.1L + 0.9W) = 2.2L + 1.8W.
- The original perimeter = 2L + 2W.
- Given that the new perimeter is 5% less than the original perimeter.

Solution

Using Both Statements Together

- From statement 1, we have the relationship between the original and new areas.
- From statement 2, we have the relationship between the original and new perimeters.
- We can now set up equations involving length, width, area, and perimeter to solve for the dimensions of the original rectangle.
- Once we have the original dimensions, we can calculate the cost to fence the plot at \$20/meter.

Conclusion

- Both statements together provide enough information to determine the original dimensions of the plot and calculate the cost to fence it.
- Therefore, the correct answer is option C: BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

Given Data:

- Total number of votes in both the National General Election and the previous Assembly Polls = 2,60,000
- Increase in the number of votes not cast for the PNC Party in the National General Election = 25%
- The PNC Party lost by a majority twice as large as that by which it had won the Assembly Polls

Solution:

Step 1: Ca
... more
- Let x be the number of votes not cast for the PNC Party in the previous Assembly Polls
- In the National General Election, the number of votes not cast for the PNC Party = x + 0.25x = 1.25x

Step 2: Calculate the number of votes cast for the PNC Party in the National General Election:
- Number of votes cast for the PNC Party in the National General Election = Total number of votes - Votes not cast for the PNC Party
- Number of votes cast for the PNC Party in the National General Election = 2,60,000 - 1.25x

Step 3: Calculate the number of votes cast for the PNC Party in the previous Assembly Polls:
- Let y be the number of votes cast for the PNC Party in the previous Assembly Polls
- According to the given data, the PNC Party lost by a majority twice as large as that by which it had won the Assembly Polls
- This implies that the number of votes cast for the PNC Party in the Assembly Polls = y + 2(y - 1.25x)

Step 4: Calculate the number of votes cast for the PNC Party in the previous Assembly Polls:
- As the total number of votes in both the National General Election and the previous Assembly Polls is 2,60,000
- Therefore, y + 2(y - 1.25x) = 2,60,000
- Solving this equation will give you the number of votes cast for the PNC Party in the previous Assembly Polls.

By following these steps, you can calculate the number of votes cast for the PNC Party in the previous Assembly Polls.
