Question

Transform the following simple sentence to a compound sentence.
He must practice very hard to play so well. [Intermediate]

• A. He must practice very hard or he would not have been able to play so well.
• B. He must practice very hard that he can play so well.
• C. He must practice very hard in order to play so well.
• D. He must practice very hard on condition that he play so well.

Answer 1

The correct option is A He must practice very hard or he would not have been able to play so well.

Compound sentence joins two or more independent clauses with a coordinator such as for, an, or, but or a semi-colon. Options B, C, and D are incorrect as no coordinator is used to join two independent clauses.

The given sentence can be broken into two predicates. Thus, option A is the correct answer.
