Definition: In this task, you're given a statement, and three sentences as choices. Your job is to determine which sentence clearly disagrees with the statement. Indicate your answer as '1', '2', or '3' corresponding to the choice number of the selected sentence.
Input: Statement: 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. Choices:  1. Teenage pregnancy out of wedlock is finally leveling off. 2. The lower pregnancy rates are mainly due to the higher contraceptive use. 3. Teen pregnancy is at an all-time low this year.
