Newspaper columnist: What caused the current recession is a hotly debated question. It is a mistake, however, to assume that answering this question is essential to improving the economy. Corrective lenses, after all, were an effective treatment for myopia long before the cause was known to be genetic.
Which one of the following most accurately expresses the conclusion drawn in the newspaper columnist's argument?The columnist says people are debating the cause of the recession, but then argues that knowing the cause is not required in order to fix the problem.
The main conclusion is that we do not need to identify the recession’s cause in order to
improve the economy.
(A) Solving a problem never requires finding the root cause of the problem.
This is too broad. The columnist is discussing the current recession, not all problems.
(B) Knowing the cause of the current recession would not necessarily enable people to find a solution to it.
This is not the conclusion. The columnist is not saying that knowing the cause would be useless. The point is that knowing the cause is not necessary.
(C) The question of what caused the current recession is subject to considerable debate.
This is background information, not the conclusion.
(D) One need not ascertain the cause of the current recession in order to improve the economy.
This is correct. It matches the claim that it is a mistake to assume that answering the cause question is essential to improving the economy.
(E) Long before the cause of myopia was known to be genetic, corrective lenses were being used as an effective treatment for the disease.
This is support for the conclusion. It is an analogy showing that a problem can sometimes be treated before its cause is known.
Answer: (D)
