Which of the following correctly identifies both an advantage and a disadvantage of using nuclear fission as a method of generating electricity?
  1. Advantage: produces only nonhazardous waste products Disadvantage: leads to thermal pollution of rivers.
  2. Advantage: uses an unlimited inexpensive fuel source Disadvantage: accelerates the rate of ozone depletion.
  3. Advantage: produces minimal greenhouse gases Disadvantage: requires long-term storage of radioactive waste.
  4. Advantage: inhibits the formation of acid rain Disadvantage: presents problems in safely containing plasma.
Explanation
Correct Response: C. Nuclear fission results in radioactive waste products that need to be stored long-term. Nuclear power plants are extremely expensive to build and represent a variety of safety hazards. However, greenhouse gases such as carbon dioxide are not produced as a result of using nuclear fission. A is incorrect because the waste produced is significantly hazardous. B is incorrect because neither is nuclear fission inexpensive nor does it accelerate the rate of ozone depletion. D is incorrect because nuclear fission does not inhibit the formation of acid rain, nor does it involve the containment of plasma.
