From this passage what can we infer

D) The Greeks feared the power of their gods.

Explanation:

From the passage we can infer that the Greeks feared the power of their gods because it mentions that they believed that the powers of the gods explained the natural events like thunderstorms and that these events occurred when a god was angry or upset for something and to avoid these situations, they performed rituals in their honor or gratitude, which indicates that they feared the powers the gods had.

basic principle: a pronoun usually refers to something earlier in the text (its antecedent) and must agree in number — singular/plural — with the thing to which it refers. the indefinite pronouns anyone, anybody, everyone, everybody, someone, somebody, no one, and nobody are always singular.
