Explain the results of Thurstone's testing and identify if it proved or disproved Spearman's Theory.
a. Thurstone's testing results showed that there was a clear pattern of specific abilities, each measuring distinct factors such as mathematical ability, verbal comprehension, and spatial reasoning. This supported Thurstone's theory of multiple intelligences but disproved Spearman's single factor theory.

b. Thurstone's testing results showed no clear pattern of specific abilities, making it difficult to identify distinct factors or intelligences. This did not support Thurstone's theory of multiple intelligences and did not disprove Spearman's single factor theory.

c. Thurstone's testing results showed a mix of specific and general abilities, indicating that both multiple intelligences and a single general factor may contribute to intelligence. This partially supported Thurstone's theory of multiple intelligences and did not fully disprove Spearman's single factor theory.

d. Thurstone's testing results were inconclusive and did not provide clear evidence for or against either Thurstone's theory of multiple intelligences or Spearman's single factor theory.
