C) is generally limited to an area within several (6 - 15) miles from the source of emissions. D) may occur hundreds of miles from the source of emissions. E) affects the whole globe uniformly.
5) Which of the following statements is/are NOT TRUE?
A) There are already hundreds of lakes in the northeastern United States and eastern Canada which are lifeless. B) It is predicted that by the year 2005, the "production" of acid rain will have diminished. C) Forests in many regions of the eastern United States show signs of damage and reduced growth. D) More research is needed to prove acid precipitation exists. E) All of the above are true.

B) some 50 nuclear power plants.
C) cars and trucks.
D) coming from the many auto and truck plants in the region. E) none of the above
