Answer:
B. He believed that sexuality is a continuum and wanted to classify people more precisely
Explanation:
Kinsey quantified in his studies heterosexuality and homosexuality on a continuous scale from 0 to 6, specified in heterosexual and homosexual experience and reactivity in each story. 0 on this scale is assigned to individuals with exclusively heterosexual sexual contacts and experiences and 6 to exclusively homosexual individuals.
