Question: My dad _____ moving to California, but eventually decided not to.
Correct Answer: considered
This question tests verb tense usage. "Considered" is the correct past tense form to match the context of the sentence where the action (considering) happened in the past before deciding not to move.

Incorrect Answers:
- considers - Present tense, doesn't match the past context of the sentence.
- considerate - An adjective meaning thoughtful/kind, not a verb form.
- considerably - An adverb meaning significantly, doesn't fit the verb slot.
