Exercise 13. Read the passage, and choose the correct answer A, B, C or D for each

 Saving the Environment: One Home at a Time
Pollution can be seen not only throughout the world, but also in our own homes. It comes 
from household chemicals, the amount of water people use and the waste people produce 
and throw away. What can be done to stop this pollution? Surprisingly, a person can help 
save the environment by doing simple things.
First, we need to recycle, which allows products to be used over and over again. Recycling 
can also reduce the number of trees cut down to produce paper products. It takes very little 
effort. It is not hard to place plastic and glass bottles, aluminum cans and paper in a bin. 
Anyone can do it.
Second, we need to watch the amount of water used in the home. It can be conserved by 
taking short shower instead of baths, repairing leaky faucets, using the dishwasher or 
washing machine only when fully loaded, or simply turning the faucet off while brushing 
your teeth.
Third, we need to reduce waste. We need to recycle whenever possible, but should also try 
to use this waste effectively. For example, grass clippings and food scraps can be made into 
compost for plants. The average person produces 4.3 pounds of waste every day, but we can 
reduce that amount by recycling and reusing.
If we do our part in our own homes, we can help keep the planet from becoming more 
polluted.
1. Pollution can be caused from the following sources except _____________.
A. house chemicals B. water from household
C. wastes D. water in rivers
2. Recycling can help us _____________.
A. never cut down trees B. use products again and again
C. place garbage bins easily D. produce more paper product
