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: The unconstrained distributed lag model coefficient estimate is 0.0012818 and the single-lag model coefficient estimate is 0.0006479. Choices:  1. The single-lag model coefficient estimate is 0.0006479. 2. A double-lag model coefficient exists, but was not taken for this model. 3. The unconstrained distributed lag model coefficient is estimated to be about 0.3431543
