1 - D (They are called indefinite because there is no clearly defined antecedent).
2 - E (While they look exactly like reflexive pronouns, intensive pronouns do not affect the meaning and are only used for emphasis).
3 - G (Interrogative sentences or phrases are, simply put, questions).
4 - B (Adjectives, i.e., noun-modifiers that can also be used as pronouns, e.g. "this" is an adjective in "take this bag" and a pronoun in "take this").
5 - A (<em>Each other</em> and <em>one another</em> are the only reciprocal pronouns in English and you use them when an action is mutual).
6 - C (Identifying relative pronouns is essential to understand relative clauses).
7 - F (You make a compound pronoun by adding -self to the object pronoun when the subject of an action and the object are the same).
