The critical reasoning question is based on a short argument, a set of statements, or a plan of action. For each question, select the best answer of the choices given. The size of particles is directly linked to their potential for causing health problems. Small particles less than 10 micrometers in diameter cause the greatest problems, as they can get deep into the lungs and some may get into the bloodstream. One being exposed to such particles can affect both the lungs and the heart of a person. But there are particles that are causing environmental effects too, few of which are given below. Which among the following below options does not talk about the effects of these particles on the environment?

A

Particles can be carried to distances by wind making lakes and streams acidic.

B

They can change the nutrient balance in coastal waters and larger river basins.

C

Causing premature death in people causing nonfatal heart attacks.

D

They can damage the sensitive forests and farm crops.

E

None of the above.
