Acid rain, which is a form of’ air pollution, currently becomes a subject of great debate because of widespread environmental damage for which it has been blamed. It forms when oxides of sulfur and nitrogen combine with atmospheric moisture to yield sulfuric and nitric acids, which may then be carried long distances from their source before they drop in the form of rain. The pollution may also take the form of snow or fog or fall down in dry forms. In fact, although the term "acid rain" has been in use .for more than a century--it is derived from atmospheric studies that were made in the region of Manchester, England--the more accurate scientific term would be’ acid deposition.’The dry form of such deposition is just as damaging to the environment as the liquid form.
The problem of acid rain originated with the Industrial Revolution, and it has been growing ever since. The severity of its effects has long been recognized i
A. acid rain has caused air pollution
B. acid rain has caused widespread environmental damage
C. acid, rain has become a much studied subject
D. acid rain travels in all directions before it rains down
[单项选择]According to the passage, rain prediction requires a quantitative description of droplet collision in turbulence for which of the following reasons

C. (C) The degree of turbulence may help forecast the formation of large-size droplets that precipitate rain.
D. (D) Such factors as warm and cold fronts and individual cloud formations could not be performed otherwise.
E. (E) The laws which govern the formation of concentration heterogeneities still need to be discerned.
