119. For a television program about astrology, investigators went into the street and found twenty volunteers born under the sign of Gemini who were willing to be interviewed on the program and to take a personality test. The test confirmed the investigators’ personal impressions that each of the volunteers was more sociable and extroverted than people are on average. This modest investigation thus supports the claim that one’s astrological birth sign influences one’s personality.
Which one of the following, if true, indicates the most serious flaw in the method used by the investigators?
(A) The personality test was not administered or scored personally by the investigators.
(B) People born under astrological signs other than Gemini have been judged by astrologers to be much less sociable than those born under Gemini.
(C) The personal impressions the investigators first formed of other people have tended to be confirmed by the investigators’ late experience of those people.
(D) There is not likely to be a greater proportion of people born under the sign of Gemini on the street than in the population as a whole.
(E) People who are not sociable and extroverted are not likely to agree to participate ininvestigation.
It is the personality test that confirmed the investigators’ personal impressions, not their willing to take the test. Choice E points out that these twenty volunteers can not represent the people born under the sign of Gemini. Millions of people born under the sigh of Gemini hate to take investigation , so they are unsociable.作者: YINDAPENG 时间: 2010-6-5 07:57
这道题，调查者found twenty volunteers born under the sign of Gemini who were willing to be interviewed on the program and to take a personality test，是调查者找的这些人，有可能100个volunteers，20个双子，80个金牛，有可能金牛比双子还外向，但调查只要了20个双子，所以得出的结论是不可信的。
