Question

as california scrambles for ways to cope with its crippling drought and the mandatory water restrictions imposed last month by gov. jerry brown, an array of ideas that were long dismissed as too controversial, expensive or unpleasant are getting a second look. one is to conserve more water; another is to turn nearby and abundant sources of water, like the pacific ocean, into drinking water through desalination. yet another is to recycle the water californians have already used. and therein lies a marketing challenge that can be even greater than the technological one –\water flowing from toilet to tap may be hard to swallow,\ john schwartz which statement best summarizes the claim the author makes in the excerpt? people actually love drinking recycled wastewater. wastewater is not easy to purify, but it is necessary for survival. california is facing a drought that has greatly affected the water supply. convincing people to drink recycled water is a more difficult task than producing it.

Explanation:

• Option A: The excerpt says there's a marketing challenge to convince people, so they don't "love" drinking recycled wastewater. Eliminate A.
• Option B: The excerpt focuses on the challenge of convincing people, not the difficulty of purification. Eliminate B.
• Option C: While California's drought is mentioned, the main claim is about the challenge of recycled water acceptance, not just the drought's effect on supply. Eliminate C.
• Option D: The excerpt states "therein lies a marketing challenge that can be even greater than the technological one" regarding recycled water, meaning convincing people is harder than producing it. This matches.

Answer:

D. Convincing people to drink recycled water is a more difficult task than producing it.
