Critical Reasoning
试题详情
题目：
Macrophages are cells that play a role in the response of the immune system of mice and other mammals to invasive organisms such as bacteria. Unlike other mice, mice that are genetically incapable of making these particular cells do not show elevated levels of nitrates when infected with bacteria.
The statements above, if true, provide the most support for which of the following conclusions?
选项:
A、Mice that are unable either to make macrophages or to make them in sufficient numbers will protect themselves from bacterial infections in some other way.
B、Mice that show elevated levels of nitrates can easily fight off most types of bacterial infections.
C、In mice, macrophages play a role in the production of nitrates or inhibit a process by which nitrates are broken down or otherwise eliminated.
D、When a healthy mouse becomes infected with an invasive organism, the number of macrophages in the mouse's body decreases.
E、Injections of nitrates into mice that lack macrophages will not enhance the ability of these animals' immune systems to fight off infection.
答案:
C
提问：
题干逻辑-M是细胞，在免疫系统中很重要，抵御细菌；某些老鼠无法产生M细胞，且感染细菌时Nitrate也不高，没说明他们的产生原理，但可以肯定M和N是正相关。问题是推出下列哪个结论-我觉得任意推出M产生了N，N可以杀菌这种言论都不严谨，毕竟文中的意思是not M, 并同时not N,没有任何其他过程或者更多解释，文中就只说了一个现象，现象已经是MN都产生了的情况，只能判定正相关；然后就选不出来了，如果C对的话，则说明了M可以产生N，但inhibit a process by which n are broken down..这个怎么可以推得？并且如果可以M产生N，也可以推N杀菌，选择了B。

提问：
这个问题不是很清楚，之前是在BC之间纠结，虽然B的most type觉得也是错的，但是先在觉得E也是加强，注入N才有E，那没E肯定也是没N啊，不明白为什么了。

提问：
GMAC买的模拟题的一道题。
Like the Drefus affair at the turn of the century and the Sacco-Vanzetti trial in 1921, the Hiss case became the political cause of an era, the more so because it was the first time a congressional hearing was shown on television.
A the more so because
B more for its being
C more for the reason that it was
D the more so for the reason because it was
E the reason of it being more so is that it was
我错选了C。排除的理由是：A:So后面要加一个结果，但是又来个because,矛盾。杀。B:its being不好，杀。 D：reason 和 because连用不好。杀。E:it being 不好。杀。
