HOPE IT HELPS YOU

Answer 2

Answer:

We are very happy here.  (Assertive Sentence)

Explanation:

The sentence that is given in the question is an exclamatory sentence. It expresses the feeling of the person who is saying the sentence. But, an assertive sentence expresses an assertion or sentence without any expression.

So, when an explanatory sentence is changed into assertive sentence, the subject is taken in the starting of sentence, and the object is pushed to back. The expression is also added in form of a very or much.
