问题补充：

If he takes on this work, he will have no choice but an even greater challenge.

A. meets

B. meeting

C. meet

D. to meet

答案：

A. meets

B. meeting

C. meet

(答案→)D. to meet

解析：考查词组：句意：如果他接受这个工作，他只好接受一个更大的挑战。have no choice but to do别无选择只好做，用不定式，注意：如果是have nothing to do but后面接动词原形，也是“只好做”，选D。
