Critical Reasoning

Politician: Fewer people are entering the labor market
now than previously. If the economy grows, the
demand for motivated and educated people will far
outstrip the supply. Some companies have already
started to respond to this labor-market situation by
finding better ways to keep their current employees.
Their concern is a sure indicator that the economy is

Which of the following is the best criticism of the
politician's reasoning?
(A) The fact that companies are making prudent
preparations for a possible future development
does not mean that this development is already

(B) The fact that some companies now try harder to
keep their employees does not mean that they
used to be indifferent to employee morale.
(C) The fact that demand will outstrip supply does
not mean that there will be no supply at all.
(D) The fact that the number of new entrants into the
labor market is declining does not mean that the
number of new entrants is lower than it has ever
been.
(E) The fact that current employees have become
more valuable to some companies does not mean
that those employees will do their jobs better than
they used to.
