Critical Reasoning An author writing a book about birth order advertised in his local paper for people who were first born. Fifty people consented to be interviewed and assessed for certain personality traits. As the writer suspected, the interview results and personality assessments showed that first-borns were more goal oriented and serious-minded than random samples of the general public. These findings support the conclusion that people are affected by their birth order. Which one of the following selections, if true, points out the most critical weakness in the method used by the author to investigate birth order characteristics? (A) Last born children are typically more laidback and calm than their older siblings. (B) The interviews and assessments were per formed by an outside firm, not by the author. (C) People who saw the newspaper ad were not more likely to be first born than the number of first-born people in the population in general. (D) The author's subsequent contact with people who were middle children or last born tended to reinforce his initial impression of the char acter traits of people who were not first born. (E) People who are not goaloriented and serious minded were not as likely to respond to the author's newspaper ad nor were they as likely to agree to participate in the study. |

So,folks here are the correct answers Critical Reasoning The correct answer is E. The argument generalizes from a small sample to the population as a whole. If the sample is shown not to be representative of the general population, then the author's conclusion is weakened. If goal-oriented and serious minded people were more likely to respond to the author's newspaper ad and agree to be studied, then this shows that the sample was not representative of the general population. Selection (E) points out this weakness and is the correct answer. If first-born people who were not serious-minded and goal-oriented simply didn't respond to the newspaper ad, then the sample studied by the author was not representative of first-borns in the general population. Rather, his sample consisted heavily of firstborns who had those two personality traits, and thus his conclusion would be seriously flawed. Selection C is tempting. Although it goes to the core of the question, that is, how representative is the study sample of the general public, it actually strengthens the writer's argument. Selection C suggests that the newspaper ad was exposed to the general public as opposed to a more limited audience.The answer is (E) |

Problem Solving The correct answer is D. Given that he purchases 11 articles for $10. Hence, he purchases 110 articles for $100. Given that he sells 10 articles for $11. Hence, he sells 110 articles for $121. Thus, by selling 110 articles he gains $21. So, in order to gain $84 he must sell 440 articles Click here for the next week's Punch |
