Question

how can people conserve water at home?
rinsing dishes with cool water instead of warm water
washing dishes only when the dishwasher is full
bathing pets with a hose instead of a bucket
eating fish bought from the store

Explanation:

• Rinsing dishes with cool vs warm water does not reduce water usage, only energy for heating.
• Running the dishwasher only when full minimizes the number of cycles, directly reducing total water consumed per load.
• Using a hose for pet bathing wastes more water than a bucket, which uses a fixed, smaller volume.
• Store-bought fish has no connection to home water conservation.

Answer:

B. washing dishes only when the dishwasher is full
