Two different scientists were studying the carbon levels of the air above a large city. They both found that the levels had increased by an average of 8% in the past decade. Scientist 1 concluded that the increase was a result of the increasing population of the city. Scientist 2 concluded that the increase was a result of an active volcano several miles from the city.

Which scientist's conclusion is valid?

a.Only Scientist 1's conclusion is valid because an increase in population is proof.

b.Neither scientists' conclusions are valid because carbon levels change so much.
