Question

read the excerpt from \water flowing from toilet to tap may be hard to swallow.\
as california scrambles for ways to cope with its crippling drought and 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.
which statement best summarizes the writer’s claim?
\bigcirc californians should not have to drink recycled wastewater, even in a drought.
\bigcirc governor jerry brown was right to impose water restrictions on californians.
\bigcirc california may have a hard time convincing residents to drink recycled wastewater.
\bigcirc there are various technologies that can supply californians with water during a drought.

Explanation:

The excerpt talks about California's water crisis and recycling wastewater as a solution, but also mentions a marketing challenge (convincing residents) which is greater than the technological one. Option A is incorrect as the text doesn't say they shouldn't drink recycled water. Option B is wrong as the focus isn't on whether the restriction was right. Option D is incorrect as the main claim isn't about various technologies but about the challenge of getting residents to drink recycled water. Option C matches as it says California may struggle to convince residents to drink recycled wastewater, which aligns with the marketing challenge mentioned.

Answer:

C. California may have a hard time convincing residents to drink recycled wastewater.
