问题 How many diseases are known to attack wheat?
What is the main idea of the second paragraph?

选项 A、 Some plants have relative immunity to a great many diseases, while others have a susceptibility to them.
B、The tolerance of a particular plant changes as the growing conditions change.
C、A blight killed virtually every chestnut tree in North America.
D、A blight may be a national infection.

答案A

解析根据段落构成的基本规律，段落开始是主题句，内容表达是顺着这一主题逐步展开。方式由一般到具体。选项C和D不可能是正确答案。剩下的A和B都是一般的论述，但从 tolerance(“忍耐力”)跟immunity(“免疫力”)意义上的相近性可以看出，B是对A的补充说明。因此正确的选项是A。
