Question

The brahmaputra is the longest river in India. CHANGE IT INTO POSITIVE DEGREE

Answer 1

No other river in India is so long as the Brahmaputra.
Longest = long (Positive degree )

Answer 2

Adjectives are the part of speech which are used to qualify or modify a noun or pronoun.

There are three degrees in the adjective that are a positive degree, comparative degree, and superlative degree. Positive degree being the base form of comparison. It is not in comparison with the comparative and superlative degree.

Therefore, when the sentence 'The Brahmaputra is the longest river in India.' is changed into positive degree, it would be written as:

No other river in India is as long as the Brahmaputra.  

Longest = long (Positive degree)
