A. Carbon dioxide and sulfur
B. Sulfur dioxide and water
C. Nitrogen oxides and sulfur
D. Nitrogen oxides and sulfur dioxide
Question 13
13.

A. These acidic gases dissolve in water droplets in clouds.
B. These alkaline gases react with water droplets in clouds.
C. They make rain happen more easily.
D. The gases react together forming sulfonitroxidic acid in clouds.
Question 14
14.
Why are carbon monoxide and soot particles found in the exhaust gases of vehicles?
A. These substances are in the fuel used in the vehicle.
B. The fuel reacts completely with oxygen in the air.
C. The fuel does not react fully with oxygen in the air.

15.
How does a catalytic converter help to reduce pollution from burning fossil fuels?
A. It filters out soot particles from the gases formed.
B. It changes pollutant gases into less harmful gases.
C. It absorbs sulfur dioxide so that it isn’t released into the air.
D. It reacts with the pollutants to form a solid, which has to be scraped out of the converter at regular intervals.
