Answer to Question 1

C An increase in consumption has nothing to do with changing labor productivity.

Answer to Question 2

There is much disagreement over what constitutes a fair tax system. One theory contends that people should bear tax burdens in proportion to the benefits that they receive from government expenditures. This is the benefits-received principle. Another theory contends that people should bear tax burdens in line with their ability to pay. This ability-to-pay principle has dominated U.S. tax policy.
