Read the passage below and answer the questions that follow.
Several minerals that form in long, thin fibers and that are valued for their
strength and resistance to heat are called asbestos.
Asbestos is primarily used as an insulator and as a fire retardant, and it was
used extensively in building materials. The U.S. government banned the use
of most asbestos products in the early 1970s.Exposure to asbestos in the air
is dangerous. Asbestos fibers that are inhaled can cut and scar the lungs,
which causes the disease asbestosis. Victims of the disease have more and
more difficulty breathing and may eventually die of heart failure. Schools in
the United States have taken this threat seriously. Billions of dollars have
been spent to remove asbestos from school buildings.
IDENTIFYING MAIN IDEAS
One reading skill is the ability to identify the main idea of a passage. The main
idea is the main focus or key idea. Frequently, a main idea is accompanied by
supporting information that offers detailed facts about main ideas.
In the space provided, write the letter of the term or phrase that best completes
each statement or best answers each question.
_____ 1. Long, thin fibers made of minerals that are valued for strength and heat
resistance are called
a. insulation.
c. asbestos.
b. fire retardant.
d. asbestosis.
_____ 2. Asbestos has been used mainly in
a. water treatment facilities.
c. commercial food packaging.
b. chicken farms.
d. building materials.
_____ 3. Why is asbestos used?
a. to control unpleasant smells by neutralizing enzymes
b. to insulate and to serve as a fire retardant
c. to filter air for those who have damage to their lungs
d. to repair walls in old buildings
_____ 4. Why isn’t asbestos used much in the U.S. today?
a. The government banned the use of most asbestos products.
b. Inflation has made it too expensive for most people.
c. A better form of insulation has been discovered.
d. The original manufacturer went out of business.

18. Accept any reasonable response. Sample
answer: The power plants inCountry A
give off oxides of sulfur and nitrogen that
combine with water in the air to make
acid precipitation. The wind carries the
acid precipita-tion over the border away
from Country A, and it falls into Country
B, where it acidifies the lake water. The
two countries could reach an agreement
for Country A to install scrubbers in the
power plants, or take other measures to
reduce emis-sions.
19. Accept any reasonable response. Sample
answers: Agree. It would be impossible to
maintain our society without any
pollution. Many businesses would fail,
and many people would lose their jobs if
businesses were banned from producing
any pollution. Even non-industrialized
societies produce pollution in the form of
smoke from fires. It makes more sense for
our society to work toward drastically
reducing pollution rather than completely
eliminating it.
