For this question, choose the option opposite in meaning to the word or phrase in italics. The gear is immanent in a car.

Immanent means existing or operating within; inherent or indwelling. When something is immanent in a system, it is an intrinsic, internal part of that system. The sentence states that the gear exists within a car as an inherent component.

The word opposite in meaning is transcendent, which means existing beyond or above; surpassing or exceeding normal limits. In philosophy, immanent and transcendent are a classic pair of opposites: immanent describes what is contained within, while transcendent describes what lies beyond or outside.

The other options are not antonyms:

• available means accessible or obtainable. Something can be both available and immanent, so this does not oppose the meaning.
• necessary means required or essential. While a gear may be necessary in a car, this describes its importance, not its relationship of being internal versus external.
• functional means working or operative. This describes whether something works, not whether it is inherent or beyond.
