Teacher: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.
Teacher: Now, understand the problem? Solve this instance: Statement: Dawkins' own honesty and thoroughness undermine his case in other ways as well--for example, when he brings up the origin of life. Choices: 1. Dawkins has discussed the origin of life. 2. Dawkins devotes much of his book to the subject of the origin of life. 3. Dawkins makes no reference to the origin of life.
