答案很好理解

49. Maizecontains the vitamin niacin, but not in a form the body can absorb. Pellagra isa disease that results from niacin deficiency. When maize was introduced intosouthern Europe from the Americas in the eighteenth century, it quickly becamea dietary staple, and many Europeans who came to subsist primarily on maizedeveloped pellagra. Pellagra was virtually unknown at that time in theAmericas, however, even among people who subsisted primarily on maize.

Which of thefollowing, if true, most helps to explain the contrasting incidence of pellagradescribed above?

(A) Onceintroduced into southern Europe, maize became popular with landowners becauseof its high yields relative to other cereal crops.

(B) Maizegrown in the Americas contained more niacin than maize grown in Europe did.

(C)Traditional ways of preparing maize in the Americas convert maize’s niacin intoa nutritionally useful form.

(D) Insouthern Europe many of the people who consumed maize also ate niacin-richfoods.

(E) Before thediscovery of pellagra’s link with niacin, it was widely believed that thedisease was an infection that could be transmitted from person to person.

结论：在那会儿的美国，P这个病没听说过，即使是持续吃玉米的人也没有这个病
这题应该是类比吧
欧洲人：主要吃玉米，得病了
美国人：主要吃玉米，应该也得病
削弱
所以这题只要找到两个的不同点，或者第三方和欧洲人一样也得病的例子

问题来了：
从形式上看，应该选B，因为只有B是明确讲出两者的不同点的，虽然逻辑不对
从逻辑上看，当然选C，可是C没有明确讲出两者的区别，即欧洲有没有转换这个营养我们不知道，不好说

有人可以解答么？

题目说的就是 Europeans and Americans都该得Pellagra，然后现在Europeans得了Americans没有，让你解释下
A 无法解释 Americans
B 无法解释 Americans
C 解释了 Americans 为什么不得Pellagra
D 无法解释 Americans 同时many 这个词太弱等于没说
E 无法解释 Americans

谢谢回复。。虽然你说了跟没说一样
问：“解释为什么美国人没得病”
论证：“因为ABDE都没解释，只有C解释了美国人为什么没得病”
结论：“所以C解释了美国人没得病”

不能因为这是文中有类比就说这是类比题吧，类比题的形式应该是类比题是AB共有一个性质c,推出AB共有另一个性质d（本质上是因果推理）. 这题明显是果因推理，此外，问题也有提示，explain the contrasting incidence of pellagra described。
