The following is from Environmental Compliance in U.S. Agricultural Policy: Past Performance and Future Potential, by Roger Claassen, Vince Breneman, Shawn Bucholtz, Andrea Cattaneo, Robert Johansson, and Mitch Morehart, AER-832, USDA/ERS, June 2004.Since its inception in the 1930s, U.S. agricultural policy has been designed to support farmers' incomes while promoting soil conservation practices. By the 1970s, however, policymakers recognized that existing farm price and income support programs were not always consistent with soil conservation efforts. An unintended effect of these programs was to encourage producers to maintain or expand production of relatively erosive crops, such as row crops (corn, cotton, soybeans), sometimes on highly erosion-prone soils. At the same time, the

Government was helping farmers reduce soil erosion and related damages through conservation cost-sharing programs. Policymakers further recognized-aside from concerns about consistency-that farm program payments could be used as incentives to encourage better conservation behavior.What hypothesis is discussed in this passage?

A. Incentive programs were having no effect on soil conservation.
B. Incentive programs were encouraging soil conservation as intended.
C. Incentive programs were not encouraging soil conservation as intended.

How thick is the deposit at the end (the “toe”) of the deposit? (Take the 6800 contour to be the top of the deposit).

The following questions are based on Map T-26a, a section of the USGS “Spring Hill, Idaho,” quadrangle (scale 1:24,000; contour interval 20 feet). You are going to calculate the approximate volume of the mass wasting deposit shown at the foot of the Pahsimeroi Mountains. What will be an ideal response?
