问题 US troops are deployed in West Africa to______.
  
(3)There are more than 1, 000 US troops in West Africa helping prevent the spread of Ebola. Thousands more are set to deploy. Some people in the Army are required to stay in enforced isolation when they return to their base in Italy.
    But for civilians who’ve traveled to the US from Ebola-stricken areas, that’s up for debate. The US government has revised its guidelines a couple of times now. Some criticize it for overreacting to the Ebola threat. Some call CDC’s guidelines too confusing. Some criticize it for not doing enough to protect Americans.
    But here’s the thing: the CDC doesn’t have the authority to enforce its guidelines, States do. And a few have added their own regarding who gets isolated and when. It’s not illegal, the Constitution allows states to impose stricter health regulations than the federal government. But they can’t be challenged.
选项 A、Different states could have their own health guidelines.
B、Health guidelines could not be revised by the government.
C、Troops could have the same health regulations as civilians.
D、Federal government could question states’ health regulations.
答案A
解析 本题考查对新闻内容的推断。由句(5—1)和(5—2)可知，有些州政府可以自己增加哪类人在什么时候被隔离的条例，故可推断出“不同的州可以有不同的医疗卫生指导条例”，故A为正确答案。
