单选题
The Social Security Act did not include health insurance because the commission considered that its inclusion would
jeopardize
the passage of the act.
【正确答案】
B
【答案解析】解析：本题中，jeopardize的意思是“危害”。B项的endanger“危害”符合题意，如：The polluted air in the city is badly endangering the health ofthe residents．(城里被污染的空气正严重地危及居民的健康。)其他三项evade“逃避”，exclude“排除”，enhance“提高”都不正确。
