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: An additional dollar of government saving and debt reduction does not automatically increase national saving and investment by a dollar because changes in saving by households and businesses will tend to offset some of the change in government saving. Choices:  1. Spending on savings and debt must reduced by 10% for their to be an increase in national saving and investment.  2. A reduction of just $1 in government saving and debt expenditures will increase national saving and investment also by $1.  3. When the government reduces saving and debt by one dollar, national saving and investment does not, in turn, increase by a dollar.
