. Pollution in the air can be harmful to human health. Pollutants can be breathed into the human body and result in loss of function and death of human cells. Air pollution can
affect many parts of the body, including the skin, blood, lungs, heart, and brain. Some
sources of air pollution that are breathed in are from natural sources (non-human related)
and some result from human activities. The list below provides some air pollution sources
related to human activities.
Two students want to compare methods that they think will reduce pollutants being
released into the air. The chart below describes two different solutions proposed by the
students to help achieve this goal.
Which student proposed a method that is MOST LIKELY to result in the greatest reduction
of air pollution AND identifies a second part that could be added to improve the method
selected?
A. Student’s Method Selected: X. Added Part: Only using motor vehicles that
require fuel combustion.
B. Student’s Method Selected: X. Added Part: Using motor vehicles that do not
require fuel combustion.
C. Student’s Method Selected: Y. Added Part: Increasing purchase of productsName Date Class
from far distances that are transported using fuel-powered vehicles.
D. Student’s Method Selected: Y. Added Part: Increasing purchase of products that
are produced using power generators.
