Make the sentence negative. Use the full form of the auxiliary verb. Susan likes apples.

The task is to make the sentence "Susan likes apples" negative using the full form of the auxiliary verb.

The auxiliary verb for the present simple tense is "do" or "does". Since the subject is "Susan" (third person singular), we use "does".

To make the sentence negative, we add "not" after "does". The full form of "does not" is "does not". The main verb changes to the base form "like".

Therefore, the negative sentence is:

Susan does not like apples.
