Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Statement: Next to the MGM Grand you will find M and M World, four stories of merchandise and memorabilia dedicated to the candy that doesn't melt in your hand. Choices: 1. The candy has many fans who love its attractions. 2. There's four stories of memorabilia dedicated to a candy. 3. That particular candy melts and becomes difficult to eat.
Solution: 3
Reason: It is said in the statement that the candy doesn't melt in your hand, but the sentence in choice 3 disagrees with it.

Now, solve this instance: Statement: legal authority allowing GAO to undertake work on its own initiative that is intended to support the Congress (research and development work). Choices: 1. GAO's ability to take work on its own initiative doesn't require legal authority at all. 2. Many members of Congress feel that this legal authority is too broad. 3. GAO's ability to take on work on its initiative requires legal authorization.
