The axis of Earth’s daily rotation is tilted with respect to the plane of its orbit at an angle of roughly 23 degrees. That angle can be kept fairly stable only by the gravitational influence of Earth’s large, nearby Moon. Without such a stable and moderate axis tilt, a planet’s climate is too extreme and unstable to support life. Mars, for example, has only very small moons, tilts at wildly fluctuating angles, and cannot support life. If the statements above are true, which one of the following must also be true on the basis of them? (A) If Mars had a sufficiently large nearby moon, Mars would be able to support life. (B) If Earth’s Moon were to leave Earth’s orbit, Earth’s climate would be unable to support life. (C) Any planet with a stable, moderate axis tilt can support life. (D) Gravitational influences other than moons have little or no effect on the magnitude of the tilt angle of either Earth’s or Mars’s axis. (E) No planet that has more than one moon can support life.
OG96. Although parapsychology is often considered a pseudoscience, it is in fact a genuine scientific enterprise, for it uses scientific methods such as controlled experiments and statistical tests of clearly stated hypotheses to examine the questions it raises. 答案D: Any field of study that employs scientific methods is a genuine scientific enterprise. 我不懂的是为什么这两道题目感觉很类似，选项上96只能选择D，而feifei 16的C就是错误呢？而且，16题中A不对的理由是什么呢？难道是因为conlusion是关于earth, Mars只是被作为例子吗？不知道这样的思路是否是对的，请各位帮忙引导下。 多谢！！！ 作者: mindyfish 时间: 2013-3-3 02:21
提供自己的思路供参考下， 狒狒16 说的是 没有一个稳定适中的轴的倾斜，这个星球的气候就会很极端不适合support生命。 但是这并不代表，有了稳定适中的轴倾斜，就一定可以support生命了。相当于支持生命需要很多条件同时达到，合适的气候只是其中一个，没有了它就没有生命，但是有了它不一定有生命。 而og16就是说的 genuine scientific enterprise 是因为他用了科学理论。正面肯定。所以两道题的逻辑是不一样的。 知道了狒狒16中的c为什么错，就知道a为什么错了，mars有了这样的气候，不一定能够有生命~
