Answer 2

Answer:

Rainbow is in south direction.

Explanation:

In grammar, predicate is used to define the subject with verb.  

Predicates come next to the subject to complete the sentence without any changes in the sense of the sentence. It is the main bit of the sentence which contains the verb.

In the above answer, the word "south direction" which is a predicate defines the subject "Rainbow".

In linguistics, it is used as adjective for the noun.

Example: The carrot looked orange.  

In the above sentence, the word “orange” which is a predicate defines the subject which is “carrot”.
