complete the sentence using relative clause.

Answer 1

The parcel which my brother sent reached me this morning.

(Relative clause - which my brother sent. It is an adjective clause.)

Answer 2

Explanation:

We use relative clause when we want to combine two sentences that are related:

The parcel which my brother sent reached me this morning. it is a simple sentence

when we break this into two sentences it will be like as follows:

1. The parcel reached me this morning.

2.  My brother sent it.

relative clauses are made by using which, whose, where and when to show the degree and extent of relation.
