Identify the degree of comparison for the underlined word.

She holds the school record for the fastest time for that competition

positive
comparative
superlative
none of the above

I think its,, positive?

Assuming you mean that "fastest" is underlined, that degree of comparison is the superlative, which is the highest degree.

AJ is right.

fast = positive
faster = comparative (comparing 2 things)
fastest = superlative (comparing 3 or more)

Fast would be the lowest degree, where it only refers to one person (ex. That person on the team is fast)

Faster is the second degree, or the comparative, where it compares two things (ex. That person on the team is faster than that other person)
Fastest is the highest degree, or the superlative, where it compares three or more things (ex. That person is the fastest of the team)

Actually, in the given sentence, "fastest" is the superlative degree of comparison. Superlative degree is used to compare more than two things or people, indicating the highest level or extreme. In this case, "fastest" indicates that she has the top record among all the competitors in the school for that particular competition. So, the correct answer is superlative.
