“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

Answer 1

B解析:

B。the key to… 意為“……的關鍵”，其中的 to 是介詞，不是不定式符號，若后接動詞要用動名詞。另一方面，名詞 demand 與 make 是被動關系(make demands 提出要求)，同時根據句中的 by the customers，可確定答案選 B
