Definition: In this task, you're given a statement and three sentences as choices. Your job is to determine the neutral choice based on your inference from the statement and your commonsense knowledge. The neutral choice is a sentence that neither agrees nor disagrees with the statement. Indicate your answer as '1', '2', or '3', corresponding to the choice number of the selected sentence. If sentence X agrees with sentence Y, one's correctness follows from the other one. If sentence X disagrees with sentence Y, they can not be correct at the same time.
Input: Statement: The second issue is addressed by assuming that the relationship between age and willingness-to-pay for fatal risk reductions can be approximated using an adjustment factor derived from Jones-Lee (1989). Choices: 1. The adjustment factor derived from Jones-Lee, used here for approximation, isn't very accurate. 2. We're assuming, for the second issue, that the relationship between age and willingness-to-pay for fatal risk reductions can be approximated. 3. Our theory doesn't allow us to approximate a number yet, so we need to leave the second issue as it is for now.
