问题 If you want to understand what life expectancy is decreasing in America, the state of West Virginia may offer some answers.
选项 A、why
B、that
C、who
D、how
答案 A
解析 这句话意思是：如果你想知道为什么美国人的预期寿命在减少，西弗吉尼亚州可能会给出一些答案。此题考查宾语从句，understand为句子谓语，后跟宾语从句，that，who，why，how，what均可引导宾语从句，但根据后文the state of West Virginia may offer some answers可知前句问的是原因，因此选A。
