问题补充：

It remains whether Jim’ll be fit enough to play in the finals.

A. seen

B. to be seen

C. seeing

D. to see

答案：

A. seen

(答案→)B. to be seen

C. seeing

D. to see

解析：动词remain后接动词时通常用不定式。另外，句首的it为形式主语，whether引导的是主语从句，由于主语从句与动词see之间为被动关系，故see用被动式。类例：Much yet remains to be done. 还有许多事需要做。That remains to be proved. 那有待证实。
