Suddenly, later that morning, the solution became clear. It was risky, but life in the Third Reich had always been risky.
A、After careful thinking suddenly I thought of way to improve the solution.
B、Though it was risky, I knew more clearly what could do that morning.
C、That morning I finally got a suitable answer to the problem.
D、I thought up a way to solve the problem.
【正确答案】：D
【题目解析】：原句意思：那天早上晚些的时候，解决方案渐渐明确。虽然有风险，可是第三帝国的生活一直都是有风险的。A项中after careful thinking意为经过仔细的思考，和原句中的suddenly（突然地）语义矛盾；B项意为虽然有风险，但是我更清楚地知道那天早上我可以做什么，与原文的语义不合；同C项相比，D项更加简洁，是对原句内容的提炼。答案为D。
