问题补充：

Professor White has written some short stories, but he is known for his plays.

A. the best

B. more

C. better

D. the most

答案：

A. the best

B. more

(答案→)C. better

D. the most

解析：此题首先不宜选B或D，因为 well known 的比较级和最高级通常是 better known和best known，有时也可以是 more well known 和 most well known，但通常不能是 more known 和 most known。至于是选A还是C，这就要看语境。由于句中涉及的只有 stories 和 plays 两个对象，故应选比较级。
