Which is correct? What rules that we follow? Thanks.
Since the tasks is hard, Peter has to burn the midnight oil to get it complete / completing / completed on time.
Hi, bear_bear: In the "since"-clause, you need "are" (plural), not "is" (singular), because the subject of the "since"-clause ("tasks") is plural. The word you need after "get it" is the past participle, "completed." Compare:
- Peter will get it done.
(NOT: Peter will get it do; Peter will get it did; Peter will get it doing.)
