Answer:
Playing with his friends is his favorite activity.
Jane does not like running during the night.
Who is your best friend?
I don't want to be friends with a person who does not care about other people.
Explanation:
1) Write a sentence using a gerund phrase with a pronoun subject:
Playing with his friends is his favorite activity.
*In this case, the gerund phrase <em>'playing with his friends'</em> is the subject of the sentence.
2) Write a sentence using a gerund phrase with a pronoun object.
Jane does not like running during the night.
*The gerund phrase <em>'running during the night' </em>is the object of the sentence. It receives the action of the verb 'to like', as this is an activity that Jane does not like.
3) Write a question using a who-form interrogative pronoun.
Who is your best friend?
*Interrogative pronoun <em>'who'</em> is used when we want to make questions about people, together with 'whose' and 'whom'. Other pronouns (which, what, etc.) are used to make questions about things.
4) Write a complete sentence using the correct who form to introduce a relative (adjective) clause.
I don't want to be friends with a person who does not care about other people.
*Relative clauses, as their name suggests, start with a relative pronoun (who, that, which, whose, etc.) Their purpose is to identify/provide more information about the noun that precedes them (the noun 'person', in this case).
