Review the passage:
Jonathon often tries to shock his composition instructor
with weird paper topics. Such as eating tarantulas or wearing women's
underwear. Professor Mauzy remains nonplussed, scandalized only by the number
of fragments in Jonathon's essays.
You chose the first part, Jonathon often tries to shock his composition instructor .... This part has a main clause: Jonathon is the subject; tries is the verb. A fragment will not have a main clause.
