Thank you.

Yes, your answer is correct.

To identify the antecedent in a sentence, you need to look for the noun or noun phrase that the pronoun in the sentence is referring to. In sentence 10a, the pronoun "their" is referring back to the noun "students." Therefore, "students" is the antecedent in that sentence.

In sentence 10b, the pronoun "their" is referring back to the noun "online classes," not "class." Therefore, "online classes" is the antecedent in that sentence.
