Definition: In this task, you're given a statement and three sentences as choices. Your job is to determine which sentence can be inferred from the statement. Incorrect choices change the meaning in important ways or have details that are not mentioned in the statement. Indicate your answer as 1,2, or 3 corresponding to the choice number of the selected sentence.
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. We're assuming, for the second issue, that the relationship between age and willingness-to-pay for fatal risk reductions can be approximated. 2. The adjustment factor derived from Jones-Lee, used here for approximation, isn't very accurate. 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.
