MTEL Chemistry Practice Exam

Category - General Chemistry

Research into the production of ethanol from corn has been promoted by society's need to:
  1. Decrease the price of corn-based food products.
  2. Stimulate job growth in automobile manufacturing.
  3. Decrease dependence on fossil fuels.
  4. Increase the number of small family-owned farms.
Explanation
Correct Response: C. Ethanol, which can be derived from corn and other plants, has the potential to become a widespread replacement for gasoline in automobile combustion engines. A is incorrect because the price of corn-based food products would possibly increase if corn is being used for ethanol production instead of as food. B is incorrect since the production of ethanol does not affect the number of automobiles produced; rather, the type of fuel used for automobiles would change. D is incorrect because the production of ethanol would be widespread and would likely be done on large-scale corporate farms.
