Environmentalist: Efforts to attain an overall reduction in carbon use by convincing people to focus on their personal use of fossil fuels cannot achieve that goal. Even if most people changed their behavior, changes in personal use of fossil fuels cannot produce the needed reductions in carbon use. Only government policies can produce change on the required scale.

The environmentalist's argument requires assuming which one of the following?


(A) Convincing most people to focus on their personal use of fossil fuels would not lead to their successfully pressuring the government into implementing policies that reduce carbon use.

(B) The calculations needed to determine how best to minimize one's personal use of fossil fuels are too difficult for individuals to carry out on their own.

(C) Efforts to convince people to focus on reducing their personal use of fossil fuels have been made only by those who are not currently involved in framing government policy.

(D) It is easier to convince the government to change its policies on carbon use than to convince people to reduce their personal use of fossil fuels.

(E) People who are concerned about environmental issues are more likely to support political candidates who support environmental issues.
