Q: What is life-cycle assessment when applied to biofuels?
- An evaluation of the energy balance in production and utilization of the biofuel
- An accounting of all greenhouse gas emissions generated in the production of the biofuel, including both agricultural and industrial processes
- An accounting of human health impacts of production and utilization of the biofuel
- All of the above
A: All of the above

Q: What are the food vs. fuel concerns with respect to bioenergy?
- Diversion of food crops for use in bioenergy
- Diversion of land that could be utilized for food crops toward cultivation of bioenergy crops
- Concern that small scale farmers in developing countries will produce and sell bioenergy commodity crops to the detriment of utilizing land, labor, and capital for the production of food crops
- Concern that policy initiatives will incentivize research and development of energy crops to the deficit of research and development initiatives that increase the productivity of food crops
- All of the above
A: All of the above

Q: True or False: Bioenergy has the potential to be carbon-neutral.
- True
- False
A: True

Q: Why consider using marginal lands for bioenergy crops?
- Cultivation of agricultural row-crops on marginal lands can lead to high rates of soil erosion; cultivation of perennial grass crops on these lands would minimize environmental degradation
- Cultivation of perennial crops on marginal lands would not compete with land for food crops
- Conversion of steep or wet land currently in food crop production to less intensive bioenergy crops has the potential to generate more ecosystem services
- All of the above
A: All of the above

Q: What is the relationship between ecosystem service trade-offs and bioenergy crops?
- Bioenergy crop production will reduce the ability of natural ecosystems to regulate natural processes
- Use of land to grow bioenergy crops will reduce the net productive output of that land and the ecosystem associated with it
- Bioenergy crop production will impede regulating and supportive functions of ecosystems
- Use of land for one function may alter the ecosystem such that it detract from other functions or services provided by that ecosystem
A: Use of land for one function may alter the ecosystem such that it detract from other functions or services provided by that ecosystem
