　　考古 from nowwsy

　　有道题是说保险的，火灾保险和洪水保险一般赔的钱一样多，但是买火灾保险比洪水保险便宜，问为什么。第一个选项是说人们为火灾投保的物品远远超过投洪水的物品。还有说火灾的破坏性比洪水大类似这样的。选项都是这样比较类型的。不太记得选项，要麻烦大家先空想一下。

　　预测：火灾保险和钱的关系吧

　　74、超重

　　V1 from 酒精灯 750

　　People who are slightly overweight tend tobe healthier than people who are slightly underweight, since a survey show that,on average, people who are moderate overweight are healthier than people whoare moderate underweight.

　　The logic flaw of the reasoning is that___.

　　① The only premise of theconclusion presupposes the truth of the conclusion.

　　我选了：②. 估计又错了…

　　75、老鼠gwd变体

　　V1 from sunflower123

　　问的是evaluate

　　Mice that have been given morphine are very likely to develop blood poisoning because bacteria that normally reside in the intestine typically respond to morphine by migrating into the bloodstream. However, when mice are given both morphine and the new drug naltrexone, blood poisoning is much less frequent, although it does still occur. These results provide support for researchers’ prediction that naltrexone will turn out to be toxic to certain types of bacteria.

　　Which of the following, if discovered to be true, would most seriously weaken the support for the researchers’ prediction?

　　A. After being administered to mice, naltrexone does not pass from the bloodstream into the intestine.

　　B Naltrexone inhibits morphine from triggering the migration of intestinal bacteria into the bloodstream.

　　C Mice that have been given naltrexone but not morphine have no greater risk of developing blood poisoning than do mice that have not been given either substance.

　　D The increased risk of blood poisoning is not the only harmful fect on mice of being given morphine.

　　E Conditions other than the presence of intestinal bacteria in the bloodstream can cause blood poisoning in mice

　　76 恐龙灭绝

　　V1 from xh65623746 720

　　我选：这样的气候不够severe 不能引起恐龙灭绝

　　CR 这题的特点是其他选项也很有道理，但是我觉得这个逻辑最好
