This question is special because requires to know the differences between "most" and a "large number". Please confirm whether my reasoning is correct.
A politician wrote the following: "I realize there are some short-comings to the questionnaire method. However, since I send a copy of the questionnaire to every home in the district, I believe the results are quite representative...I think the numbers received are so large that it is quite accurate even though the survey is not done scientifically."
The writer of the above statement makes which of the following assumptions:
(A) Most people who received the questionnaire have replied.
(B) Most people in the district live in homes.
(C) The questionnaire method of data collection is unscientific.
(D) The large number of replies means that a high proportion of those sampled have replied.
(E) A large, absolute number of replies is synonymous with accuracy.
OA is E.
Yes, the OA is easy. But please confirm whether my process of elimination for the other choices was correct:
(A) Most people who received the questionnaire have replied.- The conclusion says that the author received a large number, but "large" doesn't necesarily mean "most". 1 million of answers is a large number but it could represent only 1% of the population. Therefore, "most" is not a required assumption. - WRONG
(B) Most people in the district live in homes.- Same as in A.
(C) The questionnaire method of data collection is unscientific. - If we use the negation technique: "IT IS NOT TRUE THAT the questionnaire method of data collection is unscientific". This new assumption doesn't weaken the conclusion. WRONG
(D) The large number of replies means that a high proportion of those sampled have replied. - Same as in A.
(E) A large, absolute number of replies is synonymous with accuracy. - BINGO
