Question 1 — Analysis
(Return to Question 1) The correct response to Question 1 is (B). The argument includes the following two premises:Premise: People are accountable for their own behavior.
Premise: People are not accountable for behavior they cannot control. Here's the logical conclusion based on these two premises:Conclusion: People can control their own behavior. (A) would require that people never have control over the behavior of other people. Yet the argument does not provide this premise.
(C) would require that people should not be held accountable for the behavior of other people. Yet the argument does not provide this premise.
(D) is not a conclusion; (D) simply reiterates one of the argument's premises (the second sentence).
(E) is not inferable. The argument allows for the possibility that a person might not have control over another person's behavior which is subject to capital punishment.
Question 2 — Analysis
(Return to Question 2) The correct response to Question 2 is (E). The argument relies on the unstated assumption that prenatal care results in better health and therefore less cost to society. (E) helps affirm this assumption.
(A) is irrelevant to the argument, which makes no distinction between undocumented immigrants and other immigrants.
(B) describes benefits that might decrease the overall tax burden, but only if the prenatal care program serves to reduce the amount of infant-care benefits paid. The argument does not inform us whether this is the case. Thus it is impossible to assess the extent to which (B) would explain how the prenatal care would save the taxpayers money.
(C) actually renders the statistics more surprising, by providing evidence that prenatal care will add to society's economic burden.
(D) also renders the statistics more surprising, by providing evidence that the cost of the prenatal care program will not be offset by a particular health benefit — a benefit which would lessen the taxpayers' economic burden.
Question 3 — Analysis
(Return to Question 3) The correct response to Question 3 is (D). The original argument bases a conclusion that one phenomenon causes another on an observed correlation between the two phenomena. The argument boils down to the following:Premise: X (beautiful beach) is correlated with Y (crowd of people).
Conclusion: X (beautiful beach) causes Y (crowd of people). Answer choice (D) demonstrates the same pattern of reasoning:Premise: X (warm weather) is correlated with Y (fleas).
Conclusion: X (warm weather) causes Y (fleas). (A) demonstrates a different pattern of reasoning than the original argument:Premise: X (moose at the drinking hole) is correlated with Y (bears at the drinking hole).
Conclusion: X (moose) and Y (bear) are both caused by Z (thirst). (B) demonstrates a different pattern of reasoning than the original argument:Premise: X (scolding children) is correlated with Y (misbehavior among children).
Assumption: Either X causes Y, or Y causes X.
Conclusion: Not X (no scolding) will be correlated with not Y (no misbehavior). (C) demonstrates a different pattern of reasoning than the original argument:Premise: X (software program) causes Y (efficiency).
Assumption: Y (efficiency) causes Z (free time).
Conclusion: X (software program) causes Z (free time). (E) demonstrates a different pattern of reasoning than the original argument. In fact, (E) is not a complete argument; it contains two premises but no conclusion:Premise: X (pesticides) causes Y (anemia).
Premise: Not X (pesticide-free regions) is correlated with Y (anemia).
Question 4 — Analysis
(Return to Question 4) The correct response to Question 4 is (C). The argument boils down to the following, including the unstated assumption provided by (C):Premise: Students get enough reading practice already.
Unstated assumption (C): The reading program provides only reading practice.
Conclusion: The reading program is unnecessary. (A) is not a necessary assumption. The argument is not concerned with whether improved reading skills would help the students learn history and science. Rather, the argument involves whether the new program would help improve reading skills.
(B) is not a necessary assumption. The argument is that no additional reading practice is needed, regardless of which program provides that practice.
(D) is not a necessary assumption. The argument does not aim to compare the importance of one discipline over another.
(E) is not a necessary assumption. The argument is not concerned with whether improved reading skills would help the students learn history and science. Rather, the argument involves whether the new program would help improve reading skills.
Question 5 — Analysis
(Return to Question 5) The correct response to Question 5 is (E). Assuming the number of viable competitors has increased during the last two years, the likely result would be to draw circulation away from already viable newspapers, including the most profitable one. Given that profitability depends primarily on advertising revenues and therefore on circulation, (E) actually exacerbates the discrepancy between the two statements.
(A) and (D) help explain why the most profitable newspaper remains most profitable even though its circulation is declining: Advertisers have not yet begun to switch because the most profitable newspaper is still the most widely circulated.
(B) helps explain the discrepancy. Although the argument provides that advertisers are more likely to advertise with widely circulated newspapers than with others, it is entirely possible that other factors, such as advertising rates that a newspaper charges, also affect which newspapers advertisers choose.
(C) helps explain the discrepancy, by identifying another source of revenue and therefore another means of enhancing profitability. Simply stated, the more sources of revenue the more profitable a newspaper is likely to be. This in turn helps explain why the most profitable newspaper in the city remains the most profitable one, despite declining circulation. Admittedly, as circulation decreases so does subscriber revenue, and thus overall profitability. Yet the newspaper's profitability is still greater than it would be without revenue from its subscribers.
