Question

Which one of the following statements is true with respect to comparative and superlative suffixes? 

Answer 1

Hello.

The answer is D. The positive form of the word faster is fast.

because the positive form of the word faster truly is 'fast'. It goes - positive: fast, comparative - faster, superlative - fastest. But I'd say that B is also correct, because you do want the 'best' man to win. So, it is either D or B, or both. 
Have a nice day

Answer 2

Answer:

D. The positive form of the word faster is fast.

Explanation:

The positive form of an adjective is used with as... as to indicate that there is no contrast between the two people or things being compared. In that respect, both elements have the same characteristic described by the adjective. For example: Mike runs as fast as Tim.

The rest of the options are incorrect because in statement A it is not clear whether the comparison is between two (comparative) or three or more people (superlative); in alternative B the comparative of sad is sadder; and in option C the comparative form compares two things.
