1. According to Sessions et al., what is the main argument by an energy plant against paying a fixed cost per dry ton of wood?
a) It is not environmentally sound..
b) It does not fully account for moisture content.
c) It is not fair to the supplier.
2. According to Sessions et al., the value of a 48-foot trailer load of biomass paid as a function of moisture content based on a target feedstock cost of $40 per MW-hr decreases approximately 16% if the moisture content increases by:
a) 100%.
b) 50%.
c) 16%.

3. According to Vegh et al., what percentage of the forest area in the study is likely to burn in the future?
a) 2.3-6.4%
b) 1.2-2.3%
c) 6.5-8.5%
4. One major difference between the Vegh et al. study and an early study by Huang and Sorensen was:
a) higher treatment costs in Vegh et al.
b) higher annual burned area in Vegh et al.
c) specific levels of mortality were set lower in Vegh et al.

5. According to Cook et al., which of the following is a concern when applying aerially- or ground-applied insecticides?
a) Difficulty in reaching cones in the lower canopy with aerial application.
b) ) Difficulty in reaching cones in the upper canopy with ground application
c) Ineffective coverage inside the cones for both aerial and ground application

6. The female Diorctria beetle in the study by Cook et al. initiates attack of cones at the:
a) base of second-year cones
b) base of first-year cones
c) tip of both first- and second-year cones.
7. According to Malone et al., why is the volume estimate less accurate for white spruce trees over 18 inches in diameter?
a) Tree samples were not collected in areas of Alaska where there are large diameter white spruce.
b) There are too many small diameter tree samples in this study which skews the regression line away from the most accurate estimate of large diameter trees.
c) The sample size is small for large diameter trees because white spruce rarely attains a diameter greater than 18 inches in northern Alaska.

8. Why was a log transformation used in Malone et al. to estimate individual tree volume instead of the classic D2H form?
a) More complex equations are better at accurately estimating individual tree volume.
b) Statistically, the log transformation models produced the most accurate estimate of tree volume with the least error.
c) The log transformation models produced a high coefficient of determination (R2) of 0.994, which is the best indicator of an accurate volume estimator.
9. Which of the following visitor-specific demographic elements significantly influenced respondents' campfire utility in Lillywhite et al.?
a) Gender
b) Age
c) Income

10. In the study by Lillywhite et al., respondents were willing to pay the most (on a per night basis) for which of the six campsite attributes studied?
a) Developed restroom facilities available
b) Campground host present
c) Campfire allowed.
