which revision would best improve nia’s conclusion to reinforce her essay’s focus?

b. summarize that pollutants damage health, water, and climate, reinforcing the main points.
c. suggest readers reduce car idling and support clean - energy policies.
d. add a personal anecdote about seeing smog in her neighborhood.

Explanation:

The essay's body paragraphs discuss how pollutants harm health (lung function, asthma), water (waterways, drinking water quality), and climate (greenhouse gases, heat waves). The conclusion should reinforce these main points. Option B summarizes the pollutants' impacts on health, water, and climate, which aligns with the essay's focus. Option A introduces wildlife (not covered in body), C suggests actions (conclusion currently asks for steps but the revision should reinforce main points, not add new actions), D adds a personal anecdote (not reinforcing main points). So B is best.

Answer:

B. Summarize that pollutants damage health, water, and climate, reinforcing the main points.
