Howard gardner believes that:

a. there are 12 distinct intelligences.

b. everyone is equal in all types of intelligence.

c. iq tests are the best way to measure intelligence.

d. musical ability is a type of intelligence?

The correct answer is:

d. Musical ability is a type of intelligence

Explanation:

Howard Gardner proposed, in 1983, his Theory of Multiple Intelligences.

Gardner suggest that the traditional views of intelligence are too limited (this leaves out answer c), and that everyone have different types of intelligences (ruling out answer b).

In his theory, Gardner proposed that there are eight intelligences (not 12 like answer a says), most people possesses a range of abilities and is stronger in some of these intelligences, not all.

The eight intelligences, according to Gardner, are:

Visual-Spatial Linguistic-Verbal Logical-Mathematical Bodily-Kinesthetic Musical Interpersonal Intrapersonal Naturalistic

Everyone is equal in all types of intelligence.
