Which of the following best completes the passage below? In

for questions like this, watch for the words overestimated or underestimated in the question, such as "..the poll may have overestimated..". Once you get this, the answer is pretty easy usually.

the poll may have overestimated the proportion of voters who would vote for such a candidate, because some voters who would not vote for a candidate who uses a wheelchair might have claimed to the pollster that they would.

A- Claims they would vote. But did no. This will definitely lead to a inflated figure.
B- Vague. How does the statement overestimates? No it Can't
C- Same as C. VAgue. Cannot Overestimate
D- No mention of registered voters.
E- shared their beliefs. How does this overestimates? No

A

I would go with A, but C is tempting

After POE i was stuck with A and B. and I went ahead with B
Can somebody explain with an example why B is incorrect?

Let the number of voters be 100. 80 said they would vote for X. The argument says that this figure is an over-estimation (the estimate is over or greater than the actual), that is, that the actual number of voters voting for X may be less than 80, and asks for a reason why this may be so.

A says that some of the 80 people who said that they would vote for X might not actually vote for X. This suggests that the actual number of voters voting for X may be less than 80. This suggestion bolsters the argument's claim by providing a plausible reason.

B says the opposite. If some voters who would vote for X say, inaccurately, that they would not, then the actual number of voters voting for X may be greater than 80. In this case, the poll has underestimated (estimate < actual), not overestimated, the proportion of voters who would vote for X.



--Prasad

+A straightaway. Clearly there is an overestimation in the number of voters who vote for a gubernatorial candidate highlighted in choice A.

The key word is " overestimate" , so we need something that says less than 4/5 of voters would actually vote for such candidate. A is the answer. If B is correct, then the poll may have underestimated the proportion of voters who would vote for such a candidate. Same for other choices.

Here we have to prove that the no 4/5 has been overestimated, Option A does that clearly.B,C,D,E fails to acknowledge the fact the proportion has been overestimated.

In an exit poll of voters who had recently voted for governor, four-fifths said they would vote for a gubernatorial candidate who uses a wheelchair. However, the poll may have overestimated the proportion of voters who would vote for such a candidate, because ______________.

Some voters who would not vote for a candidate who uses a wheelchair might have claimed to the pollster that they would.

Some voters who would vote for a candidate who uses a wheelchair may not have accurately answered the pollster’s questions.

Some voters who said they would not vote for a candidate who uses a wheelchair also would not vote for candidates who express certain types of beliefs.

Some people who are not registered voters also would probably not vote for a candidate who uses a wheelchair.

Some voters who claim they would not vote for a candidate who uses a wheelchair might vote for a candidate who uses a wheelchair if that candidate shared their beliefs.

OE:

The argument may be summarized as follows:

Exit poll: 4/5ths said they would vote for candidate who uses wheelchair
Conclusion: poll may overestimate those who would vote for a candidate who uses a wheelchair

It is helpful before proceeding to the answer choices to attempt to anticipate the missing portion of the argument: an unstated premise that would support our conclusion. Why would the poll have overestimated those who would vote for a candidate who uses a wheelchair? Perhaps because voters, wanting to look good for the pollster, were not truthful in answering the pollster’s questions.

A: This explains why the poll would have overestimated the proportion of voters who would vote for a candidate who uses wheelchair. Correct.

B: This choice implies that people who would vote for a candidate who uses wheelchair told the pollster they wouldn’t, which would cause the poll to undercount, not overcount, the proportion of voters who would vote for a candidate who uses wheelchair. Incorrect.

C: Providing additional information about people who reported that they would not vote for a candidate who uses wheelchair does not support the conclusion that the proportion of people who said they would vote for a candidate who uses a wheelchair was overestimated. Incorrect.

D: The conclusion is about registered voters; this statement is irrelevant. Incorrect.

E: The idea that voters who claimed that they would not vote for a candidate who uses wheelchair might change their minds under some circumstances supports the idea that the proportion of voters who would vote for a candidate who uses wheelchair has been undercounted, not overcounted. Incorrect.
