Take the following as truth: In 1974, after a series of heated and embarrassingly public quarrels on the topic, the APA decided to resolve the question of whether or not homosexuality should be called a mental disorder by means of a ballot mailed out to its members.
Then the following statement: "The APA didn't make any action to resolve the issue of homosexuality being a mental disorder until the late 1980's." is true, false, or inconclusive?
