To solve this question, let us deploy
IMS's four-step technique.
STEP #1 ->
IDENTIFY THE QUESTION TYPELet us read the question stem to identify the question type.

The stem indicates a
method of reasoning question.
STEP #2 ->
X-RAY THE ARGUMENTLet us now read and understand the argument.
Quote:
People were asked in a survey how old they felt. They replied, almost unanimously despite a great diversity of ages, with a number that was 75 percent of their real age. There is, however, a problem in understanding this sort of response. For example, suppose it meant that a 48-year-old man was claiming to feel as he felt at 36. But at age 36 he would have said he felt like a man of 27, and at 27 he would have said he felt just over 20, and so on into childhood. And surely, that 48-year-old man did not mean to suggest that he felt like a child!
THE STATED FACT: People, who were asked in a survey how old they felt, replied, almost unanimously despite a great diversity of ages, with a number that was 75 percent of their real age.
THE AUTHOR'S POSITION: There is, however, a problem in understanding this sort of response.
SUPPORT FOR THE POSITION: For example, suppose it meant that a 48-year-old man was claiming to feel as he felt at 36. But at age 36 he would have said he felt like a man of 27, and at 27 he would have said he felt just over 20, and so on into childhood. And surely, that 48-year-old man did not mean to suggest that he felt like a child!
STEP #3 ->
FRAME A SHADOW ANSWERIn order to frame a shadow answer, we must know what the correct answer should do. The author claims there is a problem in understanding the response of people, who, despite a great diversity of ages, replied with a number that was 75 percent of their real age. He then explains his position with a hypothetical example.
-> Let us say you are this 48-year-old man who feels like you are 36, which is 75% of your actual age.
-> But wait, if you actually feel you are 36, you should have felt like you were 27 (75% of 36).
-> But then again, if you actually feel you are 27, you should have felt like you were 20.25 (75% of 27).
The continuation of this recursive pattern indicates that the perceived age keeps getting younger at each stage, eventually leading to an age in childhood. However, the author says that the 48-year-old man did not mean to suggest that he felt like a child although the recursive logic leads there. By doing so, he supports his argument that there is a problem in understanding the response of those who took part in the survey.
SHADOW ANSWER: An option that indicates the author supporting his position by using a hypothetical example.
STEP #4 ->
ELIMINATE INCORRECT ANSWERSAnswer options that do not match the shadow answer can be eliminated.
(A) projecting from responses collected at one time from many individuals of widely different ages to hypothetical earlier responses of a single individual at some of those ages -
MATCHES THE SHADOW ANSWER -
Let us analyse this answer option by asking ourselves some questions. Are there responses (in the argument) collected at one time from many individuals of widely different ages? Yes, for the responses were collected in 'a survey' and there was 'a great diversity of ages' among individuals. And has the author projected from these responses the hypothetical earlier responses of a single individual at some of those ages? Yes, he has! Do we have a reason to eliminate this answer option? No! -
KEEP(B) reinterpreting what certain people actually said in the light of what would, in the circumstances, have been the most reasonable thing for them to say -
NOT A MATCH -
Has the author reinterpreted what certain people actually said? No! Do we have a reason to read this option further? No! -
ELIMINATE(C) qualifying an overly sweeping generalization in light of a single well chosen counterexample -
NOT A MATCH -
Is there an OVERLY SWEEPING generalization? No! Well, while this gives us a reason to eliminate, let us read this option further. Is the author qualifying a (well, non-existent) overly sweeping generalization in light of a single well chosen counterexample? No! The author has given an example, not a counterexample. A counterexample is one that refutes the hypothesis, and the author's aim does not seem to be to refute anyone's viewpoint but to prove his point that there is a problem in understanding the sort of response obtained. -
ELIMINATE(D) deriving a contradiction from a pair of statements in order to prove that at least one of those statements is false -
NOT A MATCH -
Is there a contradiction from a pair of statements? And has the author derived such a contradiction? No, and no! -
ELIMINATE(E) analyzing an unexpected unanimity among respondents as evidence, not of a great uniformity of opinion among those respondents, but of their successful manipulation by their questioners -
NOT A MATCH -
Has the author analyzed an unexpected unananimity among respondents? No! For the argument, first and foremost, does not indicate the unanimity was unexpected, and second, the author has not analysed the unanimity. -
ELIMINATEHence, (A) becomes the correct answer.
