B/ Read the passage. Then write True (T) or False (F) for each sentence below:
There is too much carbon dioxide in the air. When oil, gas, and coal burn, they create a large amount of carbon dioxide. We send five million tons of carbon dioxide into the atmosphere every year. This amount will double in fifty years. This carbon dioxide lets sunlight enter the Earth’s atmosphere and heat the Earth. However, it doesn’t let as much heat leave the atmosphere and enter space. It is like a blanket. The heat can pass from the sun through the blanket to warm the Earth. The heat stays there and cannot escape through the blanket again. Scientists call this the greenhouse effect.

D/Although the world’s energy resources take many millions of years to produce, we are quickly beginning to exhaust these supplies. Recently a UN committee reported that the world’s oil and gas supplies would last about 100 years if used carefully.

If the demand continued to grow, the report said that fuel supplies would last for less than forty years. According to the report, governments must
