Another influential model, Howard Gardner's theory of multiple intelligences, suggests that intelligence is not a singular entity but rather a collection of distinct types.

Given these frameworks, which of the following best describes the primary distinction between Spearman's "g" factor and Gardner's theory of multiple intelligences?
