Take the following as truth: But now the teen-age out-of-wedlock birth rate seems to be leveling off--reflecting, Chatterbox supposes, some hard-won equilibrium between teen-agers' greater use of contraceptives, on the one hand, and their greater disinclination to marry their high school sweethearts, on the other.
Then the following statement: "The lower pregnancy rates are mainly due to the higher contraceptive use." is true, false, or inconclusive?
Answer: Inconclusive
