Read the following and then answer the questions :
Scientists believe that there is a number of reasons for climatic
changes . One reason could be the changes in the amount of heat which actually
comes from the sun at different times. Another could be volcanic dust. People
have also been adding gases such as carbon dioxide to the atmosphere. These are
called greenhouses because they hang in the atmosphere around the Earth like
the roof and walls of a greenhouse. The Earth receives heat and light from the
sun sends this back into space as infrared radiation. Much of this radiation
cannot pass through the greenhouse gases and this causes increased temperatures
near the Earth.
The amount of carbon
dioxide in the atmosphere is increasing mainly because all countries burn
fossil fuels such as oil, natural gas and coal. The destruction of the big rain
forests , which absorb carbon dioxide and give out oxygen, makes matters worse.
What can be done to prevent this situation ? Global warming is a
problem that affects every country and every person in the world. First of all,
all governments must agree to stop the destruction of the world’s rain forests
. Secondly, they must agree to reduce the amount of carbon dioxide that
transport and industries emit into the atmosphere. And we can all play a part
as individuals. We should all try to reduce the amount of carbon dioxide we
emit into the atmosphere. This can be done by driving fuel- efficient
cars. The best way people can help is to use public transport as much as
possible instead of their cars. And finally, we should plant more trees in the
cities and on farms to give us back the air we need.

answer :
5- If the amount of

absorb infrared radiation
c)
absorb carbon dioxide
d)
take in carbon dioxide and emit oxygen
