1............... it prove to be true, I shall resign from my job.

Use "Should" before the subject for a formal unlikely condition meaning "if".
2............... it possible, I would buy that apartment.
Wrong!
Use "Were" before the subject in a formal second conditional.
3If you exercised regularly, you ............... become strong and healthy.
Wrong!
The second conditional uses "would" in the main clause.
4The more he studies, ............... .
Wrong!
The comparative pattern needs "the less he understands" after "The more he studies".

The adverb "enough" comes after the adjective, so the correct phrase is "old enough".

Wrong!
Use "since" with the starting point of an action or state.
8............... having many faults, he was actually a nice guy.

Use "Despite" before a gerund phrase such as "having many faults".
9............... she was not perfect, I couldn't help admiring her.
Wrong!
Use "Although" before a subject and verb clause.

The expression "felt like" is followed by the gerund "laughing".
