Direction: Choose the word that is opposite in meaning (antonym) to the…

Concept: An antonym is a word whose meaning is the direct opposite of another word. To find it, first pin down the exact core meaning of the underlined word, then pick the option that reverses that meaning — not a word that merely relates to the same theme or means nearly the same thing (a synonym).

Application: "Unanimous" describes a decision reached with total agreement — every member of a group holds the same view, with no dissent. The direct opposite of total, group-wide agreement is a state where the group’s opinions are split, with no single shared view. "Divided" names exactly that split state, making it the antonym of "unanimous".

Cross-check: Comparing each offered word against the core meaning of "unanimous" (total agreement) confirms the choice:

• "Collective" describes something done or held by a group as a whole, without specifying whether that group agrees or disagrees — it sits closer to the idea of "unanimous" than opposite to it.

• "Agreed" expresses consent or accord, which restates the same idea as "unanimous" rather than reversing it.

• "Common" describes something shared or widespread across a group, which says nothing about whether the group’s opinions agree or conflict.

Only the word describing a split, disagreeing group reverses the core meaning of "unanimous."
