Logical Reasoning [Analysis]

Example Verbal Logic Question

“If all beaches were publicly owned, we would have to rely on government funds to maintain them. It is true that more people would have access to the ocean and beaches, but at what cost? If the beaches are not cared for adequately, soon there will be nothing left worth having access to. We should consider carefully before nationalizing more coastal property.”

Which of the following, if true, would most weaken the argument above?

A – The public does not want additional access to beaches.
B – The government is currently responsible for the maintenance of all public and private beaches.
C – The public already has some access to many beaches.
D – Other property has been nationalized in the past, with no complaints from the original owners of the property.
E – Some privately owned beaches are not well maintained.

The correct answer is B. Here’s why:

  • The evidence is that, while nationalizing will allow more people more access to beaches, it could also lead to worse beaches.
  • The author points out that access to beaches is only good if the beaches themselves are cared for adequately and are therefore desirable.
  • The author’s conclusion is the last sentence: We should consider carefully before nationalizing more coastal property. So, the author believes we have reason to be concerned that the beaches won’t be taken care of as well as when they were privately owned.
  • Note that nowhere is this claim supported; it is assumed.
  • So the answer choice must deny the central assumption and imply that the government would do a good job taking care of beaches.
  • Choice two agrees with what we want, by saying that private beaches are cared for by the government.
  • So, if the government were to nationalize those beaches, nothing changes: It should take on no new maintenance obligations, and we have little additional cause for concern about dirty beaches.
