Select the word opposite in meaning to the underlined word.

The rampant use of fossil fuels will lead to devastating consequences for the environment.

restrained

The correct answer is Option (2) → restrained

• Rampant (Adjective): (Especially of something unwelcome or unpleasant) spreading uncontrolled or unchecked.

• Restrained (Adjective): Characterized by reserve or moderation; controlled or held back.

The opposite of the uncontrolled spread implied by rampant is the moderation and control implied by restrained.

Why the Other Options Are Incorrect: 

• Unchecked is a synonym of rampant.

• Widespread and inordinate (excessive) are related to the expansive or excessive nature of something rampant, making them conceptually closer to its meaning, not its opposite.
