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 above changes would allow substantial reductions in the complexity of rates and in the complexity of the data systems, which in turn would allow improvements in the costs and volumes for the subclasses that remained. Choices:  1. Reduction of rate complexity will be achieved. 2. The above changes will not allow reductions in complexity of rates and data systems. 3. As per the changes above, substantial reductions in the complexity of rates and data systems will be possible.
