Critical Reasoning 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 per sonality 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' later 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 in such an investigation. |

So,folks here are the correct answers Critical Reasoning The correct answer is E. The argument generalizes from a sample to the general population. To weaken it, we must show that the sample is not representative of the general population. Now if only sociable and extroverted people are likely to submit to an interview, then the sample would not represent the general population. The answer, therefore, is (E). Don't make the mistake of choosing (D). Although it addresses the issue of the representativeness of the sample, it actually strengthens the argument by showing that the sample is typical of the general public. |

Problem Solving The correct answer is C. We want a factor of 840 which is in the form 4x. Since 4x must divide 840, it is evident that x must divide 210. So the question is all about calculating the factors of 210. Hence the total number of factors of 120 = 2×2x2×2 = 16 Click here for the next week's Punch |
