Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 26 to 32.
An air pollutant is defined as a compound added directly or indirectly by humans to the atmosphere in such quantities as to affect humans, animals, vegetation, or materials adversely. Air pollution requires a very flexible definition that permits continuous change. When the first air pollution laws were established in England in the fourteenth century, air pollutants were limited to compounds that could be seen or smelt - a far cry from the extensive list of harmful substances known today. As technology has developed and knowledge of the health aspects of various chemicals has increased, the list of air pollutants has lengthened. In the future, even water vapour might be considered an air pollutant under certain conditions.
Many of the more important air pollutants, such as sulfur oxides, carbon monoxide, and nitrogen oxides, are found in nature. As the Earth developed, the concentration of these pollutants was altered by various chemical reactions; they became components in biogeochemical cycles. These serve as an air purification scheme by allowing the compounds to move from the air to the water or soil. On a global basis, nature's output of these compounds dwarfs that resulting from human activities. However, human production usually occurs in a localized area, such as a city. In such a region, human output may be dominant and may temporarily overload the natural purification scheme of the cycles. The result is an increased concentration of noxious chemicals in the air.
The concentrations at which the adverse effects appear will be greater than the concentrations that the pollutants would have in the absence of human activities. The actual concentration need not be large for a substance to be a pollutant; in fact, the numerical value tells us little until we know how much of an increase this represents over the concentration that would occur naturally in the area. For example, sulfur dioxide has detectable health effects at 0.08 parts per million (ppm), which is about 400 times its natural level. Carbon monoxide, however, has a natural level of 0.1 ppm and is not usually a pollutant until its level reaches about 15 ppm.
According to the passage, human-generated air pollution in localized regions……
A.will damage areas outside of the localized regions
B.can overwhelm the natural system that removes pollutants
C.will react harmfully with natural pollutants
D.can be dwarfed by nature's output of pollutants

Choose the word or phrase (A, B, C, or D) that best fits each space in the following passage.
         WHY DO ANIMALS GO EXTINCT?
         Different kinds of animals have appeared and disappeared throughout Earth's history. Some animals go extinct because the climate (31)                 they live changes. The climate may become wetter or drier. It may become warmer or cooler. If the animals cannot change, or adapt, to the new climate, they die.
         Some animals go extinct bacause they cannot (32)              with other animals for food. Some animals go extinct because they are killed by enemies. New kinds of animals are always evolving. Evolving means that the animals are changing (33)               from generation to generation. Small differences between parents, children, and grandchildren slowly add up over many, many generations. Eventually, a new kind of animal evolves.
         Sometimes many of the animals on Earth go extinct at the (34)                 time. Scientists call this a mass extiction. Scientists think there (35)                  at least five mass extinctions in Earth's history. The last mass extinction happened about 65 million years ago. This mass extinction killed off the dinosaurs.

A.have been  
B.will be   
C.are
