15. which sentence uses comparison correctly? a. which feels badder to you, biting your tongue or stubbing your toe? b. which feels worse to you, biting your tongue or stubbing your toe? c. which feels more worse to you, biting your tongue or stubbing your toe? d.which feels worst to you, biting your tongue or stubbing your toe? i know a isn't the answer but .

If you mean which is more grammatically correct, then it is B) Which feels WORSE to you,  biting your tongue or stubbing your toe. This is correct because in A, they use 'badder' and you don't use that word, you use worse. C is incorrect because worse basically defines 'more bad' in a way, which means we don't need to use 'more' it's just worse. It isn't D because which feels WORST isn't gramatically correct.

i say essential becuase Essential and Nonessential Adjective Clauses. Remember that an adjective clause is a dependent clause that acts like an adjective in the sentence. This means that it gives more information about a noun or pronoun in the sentence. Sometimes the information given by the adjective clause is essential.
