Radioactive pollutants

  • A.are limited in their effect
  • B.will infect the atmosphere for thousands of years
  • C.will be on the surface of earth for a very long time
  • D.will dissipate in short span of time

Answer: C

Correct answer: will be on the surface of earth for a very long time

The passage says radioactive pollutants now on the earth surface will be found there for generations, and in the case of Carbon-14, for thousands of years. The thousands of years belong specifically to Carbon-14, which is why the option applying them to the atmosphere overstates the text.
