Based on Climate Data from Mount Hua in China, Scientists

Based on climate data from Mount Hua in China, scientists have established the following link between air pollution and precipitation patterns:

A) High visibility-that is, low levels of air pollution - is linked with substantially more precipitation.
B) Low visibility - that is, higher levels of air pollution - is linked with substantially more precipitation.
C) The type of air pollution determines the amount of precipitation.
D) A combination of the type of air pollution and surface temperatures determines the amount of precipitation.
