This question is incomplete, since it is missing the sentence we are supposed to analyze. I've found the complete question online. It is as follows:
"To the best of our knowledge, he decided that his major would be acting." Which does the sentence contain?
a) a conjunction
b) a gerund
c) an infinitive
d) a participle
Answer:
The sentence contains letter b) a gerund.
Explanation:
Gerunds are formed by adding -ing to verbs, but they function like nouns in a sentence.
In "To the best of our knowledge, he decided that his major would be acting," we have the verb "be" functioning as a linking verb, connecting the subject "major" to a word or words that provide information about that it. That word providing information on the subject is the gerund "acting", which therefore functions as a subject complement in this sentence.
