Research the use of genetically modifi ed corn in the United States and determine the percentage of the crops produced for the last two years that were genetically modified.
What will be an ideal response?
Genetically modified (GM) crops were introduced in 2006, principally
to increase resistance to disease and pests. Since that time, a debate has
continued about the benefits and drawbacks of GM plant usage. Studies
have not shown any findings that would limit their usage. In consequence,
the usage has grown, as Figure below shows. More information is available
from the following United States Department of Agriculture (USDA)
website: http://www.ers.usda.gov/Publications/eib11/.

A manufacturing software engineer at a major aerospace corporation has been assigned the management responsibility of a project to design, build, test, and implement AREMSS, a new-generation automated scheduling system for routine and expedited maintenance. Reports on the disposition of each service will also be entered by field personnel, then filed and archived by the system. The initial application will be on existing Air Force in-flight refueling aircraft. The system is expected to be widely used over time for other aircraft maintenance scheduling. Once fully implemented, enhancements will have to be made, but the system is expected to serve as a worldwide scheduler for up to 15,000 separate aircraft. The engineer, who must make a presentation next week of the best estimates of costs
over a 20-year life period, has decided to use the life-cycle cost approach of cost estimation. Use the following information to determine the current annual LCC at 6% per year for the AREMSS scheduling system. What will be an ideal response?
