Question
A. One study showed that conversion to plastic car materials
in Europe saved 26 percent in fuel. Cars that use less fuel
produce fewer of the greenhouse gases that scientists say
lead to climate change.
B. Both oil and natural gas exist underground because of the
decomposition of living things, which are made largely
from the element carbon.
C. Still, chemists are working on alternatives because they
want the world to rely less on materials made from oil and
gas--which are in limited supply -and more on sustainable
materials, such as plant-based products.
D. The age of petrochemicals took root shortly after World
War II ended in 1945. During the war, the U.S. experienced
a shortante of rubber (natural rubber is made from plants).
Answer
A. Plastic car materials in Europe saved 26% in fuel.
B. Oil and natural gas come from decomposed living things.
C. Chemists are developing sustainable materials to reduce reliance on oil and gas.
D. The petrochemical age began after World War II due to a rubber shortage.
