Question

Which text from the passage best supports the conclusion that gray water should be used primarily for landscape irrigation rather than other purposes?

a) "[Insert relevant passage text about the benefits of gray water for plants and soil.]"
b) "[Insert relevant passage text discussing the limitations of using gray water for indoor purposes.]"
c) "[Insert relevant passage text highlighting the regulatory aspects favoring gray water use in landscaping.]"
d) "[Insert relevant passage text comparing the environmental impact of using gray water for irrigation versus other applications.]"

Answer 1

The best supporting text for the conclusion that gray water is more suitable for landscape irrigation would discuss its limitations for indoor use. Option number C is correct.

Step-by-step explanation:

The question seeks textual evidence to support the conclusion that gray water should be primarily used for landscape irrigation. The best option would be "b) [Insert relevant passage text discussing the limitations of using gray water for indoor purposes.]" since it directly addresses the limitations that make other uses less suitable compared to irrigation. However, mention of the benefits of gray water for plants and soil (a), regulatory aspects favoring its use in landscaping (c), and environmental impact comparisons (d) may all serve as supplementary support for this conclusion, focusing on positive aspects and regulatory incentives for gray water use in irrigation and potential environmental benefits.

Wastewater reuse is a long-established practice, particularly beneficial in arid countries where it serves as an alternative water source. The content of treated gray water can nourish plant life and improve soil health, which can be of particular importance where water is scarce. The text also highlights the importance of water management in sustaining our way of life, including the use of water for purposes beyond basic survival.
