—How do you deal with the disagreement between the company and the customers?
—The key _______ the problem is to meet the demand _______ by the customers.
A、to solving, making
B、to solving, made
C、to solve, making
D、to solve, made
【正确答案】：B
【题目解析】：试题分析：考查非谓语动词用法。The key to sth/doing sth指做某事的关键To是介词后面接动名词或者名词。第二空needs与make构成被动关系，使用过去分词短语做定语修饰the needs.句意：解决问题的关键是满足顾客提出的需要。故B正确。
