Question

changing your toilet can reduce water pollution because ________. a. the sewage is partially treated in the toilet before entering the sewer system b. chemicals added by new toilets neutralize the pathogens in the water c. more efficient plumbing uses more water and creates larger volumes of waste d. more efficient plumbing uses less water and creates smaller volumes of waste please select the best answer from the choices provided a b c d

Explanation:

• Option a: Toilets do not partially treat sewage. Sewage treatment occurs in wastewater treatment plants.
• Option b: New toilets do not add chemicals to neutralize pathogens. Pathogen removal is part of sewage treatment processes.
• Option c: More efficient plumbing uses less water, not more. Using more water would create larger waste volumes, which is contrary to reducing pollution.
• Option d: More efficient plumbing (like low - flow toilets) uses less water. Since less water is used, the volume of wastewater (which can carry pollutants) is reduced. This helps in reducing water pollution as there is less contaminated water to treat or that could potentially leak and pollute.

Answer:

D. more efficient plumbing uses less water and creates smaller volumes of waste
