 QUESTIONS 164–165 ARE BASED ON THE FOLLOWING PASSAGE:

Global warming is the result of increasing of carbon dioxide gas in the

environment. It is causing a heating effect on the surface of the Earth. Global
warming increases the evaporation in the atmosphere. Vapour is also a
greenhouse gas, so this cause more warming. When we burn fossil fuel, it
produces carbon dioxide. Vehicles are also discharging carbon dioxide. Carbon
dioxide and other greenhouse gases are increasing day-by-day due to burning of
fossil fuels, deforestation, using of fertilizer in agriculture, population growth,
urbanization, industrialization. Now global warming has turned out in a big
problem for environment.

Q: - What does global warming refer to?

⚫ Global warming refers to the increase of temperature on the surface of the earth.
