Television Announcement:

(A) The unemployment rate in this state is higher today than it was when Mormont was appointed CEO.
out of scope as unemployment rate is not discussed

(B) The average pay for power plant jobs in the state was at a five-year low when Mormont was appointed.
it strengthens the argument

(C) In each year that Mormont has been CEO, the average pay for the power plant jobs that were eliminated has been higher than the average pay for jobs statewide.

(D) Most of the power plant jobs eliminated while Mormont has been CEO were in sectors of the industry that were more efficiently run by technology.
this doesn't helps to disprove that the average paycheck for power plant workers statewide has been getting steadily bigger each year that Mormont has been CEO
(E) The average pay for power plant jobs in this state is currently lower than it is for jobs in less populated states.
pay of jobs outside states is not the issue here

hence only left is C
OA: C

(C) In each year that Mormont has been CEO, the average pay for the power plant jobs that were eliminated has been higher than the average pay for jobs statewide. [ voila! it righfully weakens the very same link we had established. if the higher paid employees were the ones who were eliminated then it does not make sense to think that salaries are growing bigger each year. Correct!]
