Extremeness of an attitude indicates ________.

how positive or negative an attitude is

The correct answer is Option (2) → how positive or negative an attitude is

The extremeness of an attitude indicates how positive or negative an attitude is. It indicates the intensity of the attitude along the positive-negative continuum.

Other options:

• "Whether an attitude is positive or negative" refers to the valence of the attitude, not extremeness.

• "How many attitudes there are within a broader attitude" refers to complexity or multiplexity of attitudes.

• "The role of an attitude in the attitude system" refers to the centrality of the attitude.
