Question

A. They were all shocked at his failure in the competition.
B. He is too important for tolerating any delay.
C. There are not many men who are so famous that they are frequently referred to by their short names only.
D. The small child does whatever his father does.
___

Answer 1

Sentence B should not contain the continuous form of the verb 'tolerating'. It should read 'He is too important to tolerate any delay'. In sentence C, the phrase 'short names' is inappropriate. It should be 'initials' instead. Famous men are frequently referred by their initials.

Sentences A and D are correct.
