Question

he comes here at four.make it complex
​

Answer 1

He comes here when it is four.

Answer 2

Complex Sentence :

He comes here when it is four.

Explanation:

A complex sentence communicates more than one idea, so it is like a compound sentence in a way. However, the ideas are not equal. This is because one part is like a simple sentence, so it can stand on its own. The other part can't - it needs something else to support it. Thus, you may say that a complex sentence contains an independent clause and one or more dependent clauses.

Here, the independent clause is 'He comes here..' and the dependent clause is '...when it is four', thereby, together forming a complex sentence.
