Read the following passage and answer questions 9-13 below

A greenhouse is a building whose sides and roof are made of glass so that the temperature inside is

magnified. And it's used to grow plants that need high temperatures. This is to illustrate an example of how

man could be causing changes to the climate. These changes result from increasing the carbon dioxide levels

in the atmosphere, thus raising the surface temperature of the Earth. And this is known as the "Greenhouse

Effect."

CO2 is a normal component of the atmosphere and until recently has not been considered an air pollutant.

But average global CO2 concentrations have been increasing since 1860, with particularly sharp increase in

1958. The main reason for this continuous increase in CO2 build-up is the burning of fossil fuels. During the

past 100 years, the CO2 content of the atmosphere has already risen by about 15% - from about 290 to about

340 parts per million. And it's still rising.

Although the CO2 content of the atmosphere is only about 0.032%, it's a major factor in determining average

global temperature. Incoming sunlight consists of many wavelengths including some very dangerous ones.

But ozone in the upper atmosphere and water vapor and CO2 in the lower atmosphere filter out or destroy

most of the harmful wavelengths, so what reaches the Earth is mostly visible light. It's absorbed by land, sea

and cloud and is reradiated in the atmosphere as longer wavelength infrared radiation, or heat, as the Earth

cools. Much of this infrared radiation is absorbed by CO2. The CO2 then radiates a portion of the absorbed

heat energy back to the Earth to warm the atmosphere. Rather like the glass in a greenhouse or a car window

on sunny day, CO2 in the atmosphere acts as a one-way filter that allows visible light to enter the Earth's

atmosphere, but prevents longer wavelength heat radiation from leaving. Assuming that energy is arriving

from the sun at a constant rate, then as the level of CO2 increases, the average surface temperature of the
