The number of new homes constructed in the United States last year is down almost 15 percent from the number of new homes constructed during the previous year. We can conclude that housing construction is on a downward trend and the number of homes built will continue to decline.

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

A. The housing figures are computed using a representative sample of home builders across the United States and not by calculating the exact number of homes constructed.
B. Last year much of the United States saw unseasonably poor weather throughout the entire summer, which is the prime housing construction season.
C. Home builders tend to leave the industry if the number of homes constructed declines more than 15 percent over the previous year's total, leading to a further drop in houses constructed.
D. The 15 percent drop is the largest such decline in five years.
E. State government incentives are known to have an effect on the number of houses that are constructed in any given year.

[quote="mayursurya"]The number of new homes constructed in the United States last year is down almost 15 percent from the number of new homes constructed during the previous year. We can conclude that housing construction is on a downward trend and the number of homes built will continue to decline.

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

A. The housing figures are computed using a representative sample of home builders across the United States and not by calculating the exact number of homes constructed.(contender)
B. Last year much of the United States saw unseasonably poor weather throughout the entire summer, which is the prime housing construction season.(it provides the reason for the decline but doesn't weaken)
C. Home builders tend to leave the industry if the number of homes constructed declines more than 15 percent over the previous year's total, leading to a further drop in houses constructed.(strengthen the argument)
D. The 15 percent drop is the largest such decline in five years.(restate the drop,not a weakner)
E. State government incentives are known to have an effect on the number of houses that are constructed in any given year.(it provides a factor responsible for construction of houses)

Choice A says that housing figures are determined by home builders rather than by construction of homes.so on the basis of 15% decline in construction of home we can't conclude that no of new homes will continue to decline.

Choice A

Please correct if I am wrong.
Thanks

Last year much of the United States saw unseasonably poor weather throughout the entire summer, which is the prime housing construction season.
Option B tells us it was not expected that in the prime housing construction season USA would get to see unseasonably poor weather throughout the entire summer. So in prime housing construction season construction of homes couldn't happen as it happened earlier.
In Option A, you see that statement gives a general information. As if it happens every time, but here the question specifically asked to give the reasons with reference to last two years data. Moreover, we have to choose the answer which is more potent for the contender.

The number of new homes constructed in the United States last year is down almost 15 percent from the number of new homes constructed during the previous year. We can conclude that housing construction is on a downward trend and the number of homes built will continue to decline.

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

A. The housing figures are computed using a representative sample of home builders across the United States and not by calculating the exact number of homes constructed.
Explanation: What if the exact number of houses constructed have declined too? In that case, the downward trend and the number of houses built would probably continue. Hence INCORRECT

B. Last year much of the United States saw unseasonably poor weather throughout the entire summer, which is the prime housing construction season.
Explanation: Poor weather was the reason behind the decline in construction last year and the same resulted in the decline of new construction. Therefore many new homes would be constructed this year if the weather conditions are favourable.- CORRECT

C. Home builders tend to leave the industry if the number of homes constructed declines more than 15 percent over the previous year's total, leading to a further drop in houses constructed.
Explanation: IRRELEVANT

D. The 15 percent drop is the largest such decline in five years.
Explanation: IRRELEVANT

E. State government incentives are known to have an effect on the number of houses that are constructed in any given year.
Explanation: IRRELEVANT

How can we assume , construction can not go on during poor weather? A directly attacks the way data is collected.



I think i got the answer. A says "representative data"..a representative data always shows the right picture of the population.
