标题: 一题逻辑，感觉很无语

Calorie restriction, a diet high in nutrients but low in calories, is known to prolong the life of rats and mice by preventing heart disease, cancer, diabetes, and other diseases. A six-month study of 48 moderately overweight people, who each reduced their calorie intake by at least 25 percent, demonstrated decreases in insulin levels and body temperature, with the greatest decrease observed in individuals with the greatest percentage change in their calorie intake. Low insulin level and body temperature are both considered signs of longevity, partly because an earlier study by other researchers found both traits in long-lived people.

If the above statements are true, they support which of the following inferences?

		Calorie restriction produces similar results in humans as it does in rats and mice.
		Humans who reduce their calorie intake by at least 25 percent on a long-term basis will live longer than they would have had they not done so.
		Calorie intake is directly correlated with insulin level in moderately overweight individuals.
		Individuals with low insulin levels are healthier than individuals with high insulin levels.
		Some individuals in the study reduced their calorie intake by more than 25 percent.

为何无语呢？

是觉得这题做的容易，无聊？
这种题Veritas Prep介绍就是选一定正确的选项。E是可以完全保证的。
each reduced their calorie intake by at least 25 percent, demonstrated decreases in insulin levels and body temperature, with the greatest decrease observed in individuals with the greatest percentage change in their calorie intake.
至少25%。然后有不同，所以一部分超过25%。

其它都无法担保。这种题，就像你踩着石头过河，只能一步一步走。其它答案都有思维跳跃，加入额外假设。考题训练是我们分析问题时不能加入额外假设，如果加入，自己也是知道，这样可以对额外假设来收集数据分析等加以论证。

感觉这个像是在复数题目的条件，都不能算推理了

也没有啊 each reduced their calorie intake by at least 25 percent。那包括都是25%这种情况。
with the greatest decrease observed in individuals with the greatest percentage change in their calorie intake.
说明他们有不同change in their calorie intake，所以一部分超过25%
这里还是有个细微的推导过程。

感觉最危险的就是这种题了……在题库里肯定是easy级别，选错了基本告别700了
