Critical Reasoning: Conclusion Strengthening Questions

A recent survey shows that the use of public libraries has dwindled to 19% of what it was 30 years ago. The digital age has led to huge amounts of information being placed at the fingertips of people while they sit in their own homes. Because libraries serve an important function, their services should not be ceased.

Which of the following, if true, most strengthens the author's conclusion?

Incorrect.

[[snippet]]

Since the conclusion deals with libraries of today, the data provided by this answer choice about libraries 30 years ago is irrelevant.

Incorrect.

[[snippet]]

This answer choice does not strengthen or weaken the conclusion since it makes a judgment that applies to both real books and digital information and therefore has no bearing on the future of libraries.

Incorrect.

[[snippet]]

This answer choice weakens the argument's conclusion by stating that the digital age can replace services that a library offers. This fact leads us to believe that libraries are less useful than they once were. However, we are looking for a statement that strengthens the author's conclusion that libraries should not be closed.

Incorrect.

This answer choice weakens the argument's conclusion by presenting a negative aspect of keeping libraries open. However, we are looking for a statement that strengthens the author's conclusion that libraries should not be closed.

Superb work!

[[snippet]]

This answer choice provides us with a reason why libraries should not be closed, and by doing so, strengthens the conclusion. If Internet prices are high in some areas, some people may not be able to pay them. Therefore, libraries should not be closed in order to cater for people that do not have Internet connections at home.

The libraries that existed 30 years ago acted as important meeting places for intellectuals and public figures.
Sources of information, whether digital or hard copy, should always be verified for accuracy.
Digital versions of many books are being created that can be bought via stores on the internet.
In some areas, due to a lack of competition between service providers, Internet prices are extremely high.
Libraries demand funding which is partly provided by taxes paid by the public.
