78. A group of children of various ages was read stories in which people caused harm, some of those people doing so intentionally, and some accidentally. When asked about appropriate punishments for those who had caused harm, the younger children, unlike the older ones, assigned punishments that did not vary according to whether the harm was done intentionally or accidentally. Younger children, then, do not regard people’s intentions as relevant to punishment.
Which of the following, if true, would most seriously weaken the conclusion above? (B) In these stories, the severity of the harm produced was clearly stated.
(E) The younger children assigned punishments that varied according to the severity of the harm done by the agents in the stories. OG解释:Choice B and E support the conclusion by suggesting that another factor-severity of harm-either possibly (choice B) or actually (choice E) motivated variations in the punishments assigned by younger children. 101. Biological functions of many plants and animals vary in cycles that are repeated every 24 hours. It istempting to suppose that alteration in the intensity of incident light is the stimulus that controls these daily biological rhythms. But there is much evidence to contradict this hypothesis. Which of the following, if known, is evidence that contradicts the hypothesis stated in lines 2-5 above? D) Certain single-cell plants display daily biological rhythms even when the part of the cell containing thenucleus is removed. OG解释:choice D provides evidence against a different hypothesis, namely, that it is the cell nucleus of single-cell plants that controls their biological cycles. 105. Treatment for hypertension forestalls certain medical expenses by preventing strokes and heart disease.Yet any money so saved amounts to only one-fourth of the expenditures required to treat the hypertensive population. Therefore, there is no economic justification for preventive treatment for hypertension. Which of the following, if true, is most damaging to the conclusion above?
(C) In matters of health care, economic considerations should ideally not be dominant. OG解释:Choice C undermines a different conclusion-that society should not support treatment for hypertension-but does not damage the conclusion actually drawn. 我的问题: 78的D,E支持原结论, 那么101的D和105的C是对原结论的支持?
