Plant Y thrives in environments of great sunlight and very little moisture. Desert X is an environment with constant, powerful sunlight, and next-to-no mois­ture. Although Plant Y thrives in the areas surrounding Desert X, it does not exist naturally in the desert, nor does it survive long when introduced there.

18. Which of the following would be most useful in explaining the apparent discrepancy above?

A. Desert X's climate is far too harsh for the animals that normally feed on Plant Y.

B. For one week in the fall, Desert X gets consistent rainfall.

C. The environment around Desert X is ideally suited to the needs of Plant Y.

D. Due to the lack of sufficient moisture, Desert X can support almost no plant life.

E. Plant Y cannot survive in temperatures as high as those normally found in Desert X.

Although air pollution was previously thought to exist almost exclusively in our nation's cities, the recent increase in the number of persons suffering from illnesses attributed to excessive air pollution leaves us no choice but to conclude that ether, non-urban areas are now affected.

A. The nation's cities have seen a marked decrease in their levels of air pollution.

B. The nation has experienced a sharp decrease in the number of people moving out of its cities.

C. Illnesses due to air pollution are among the least common causes of death to urban dwellers.
