Question

in his article, john schwartz presents the reasoning that wastewater recycling has a public perception challenge to overcome. which piece of evidence sufficiently supports this reason?
○ purifying wastewater involves a number of steps, including reverse osmosis.
○ los angeles county uses recycled wastewater in irrigation and in boilers.
○ governor jerry brown has established water restrictions in california.
○ activists have coined the slogan \toilet to tap\ to discourage the use of wastewater.

Explanation:

To determine which evidence supports the claim that wastewater recycling has a public perception challenge, we analyze each option:

• Option 1 describes the steps of purifying wastewater, which is about the process, not public perception.
• Option 2 shows a use of recycled wastewater, indicating acceptance, not a perception challenge.
• Option 3 is about water restrictions, not related to public perception of wastewater recycling.
• Option 4: Activists using the slogan "toilet to tap" to discourage wastewater use shows negative public perception towards it, supporting the claim.

Answer:

D. Activists have coined the slogan "toilet to tap" to discourage the use of wastewater.
