Select the pronoun. Dad will tell us a riddle.

"Dad"

Explanation:

Pronoun: a word that can function by itself as a noun phrase and that refers either to the participants in the discourse (e.g., I, you ) or to someone or something mentioned elsewhere in the discourse (e.g., she, it, this ).

i think the answer would mist likely be an adjective clause, because unhappy is an adjective.
