Question

In "water flowing from toilet to tap may be hard to swallow" what reason does Schwartz give to support his claim

Answer 1

Even though recycled water is accepted for uses like irrigation, recycling toilet water to tap water may make people feel reluctant and disgusted about the idea of drinking it.

Besides, the phrase "toilet to tap" may reduce the strength of the advantages of recycling water. The reason is people may make prejudices based on their feelings about the dangers of drinking recycled toilet water.
