Relative words gain their meaning from comparison.

a. True

b. False

The answer is false.

Relative words are who, whom, whose, what, which, that, where, and when.

They introduce subordinate clauses and gain their meaning by giving more information about the noun.

For example, "The book, which I read last year, was really good!" In this sentence, the word "which" is not making a comparison; rather, it is just telling us more information about the subject, the book.
