Media consultant: Electronic media are bound to bring an end to the institution of the traditional school in our culture. This is because the emergence of the traditional school, characterized by a group of students gathered with a teacher in a classroom, was facilitated by the availability of relatively inexpensive printed books. Currently, however, the function of books in communicating information is gradually being taken over by electronic media. So, it is inevitable that the traditional school will not survive in our culture.

Summarize Argument

The media consultant concludes that electronic media will bring an end to traditional schools. He supports this by saying that the availability and affordability of printed books helped to bring about traditional schools, and that electronic media is now fulfilling the purpose of books in communicating information.

Identify and Describe Flaw

The media consultant assumes that, because having books helped to start traditional schools, not having books (because they’re being replaced by electronic media) will end traditional schools. The problem is that he never actually showed that books are necessary to traditional schools. Just because books helped these schools emerge doesn’t mean that they’re necessary for the schools to continue to exist in the future.

A
presupposes as a premise what it is trying to establish

This is the cookie-cutter flaw of “circular reasoning,” where the premise is simply a restatement of the conclusion. The media consultant doesn’t make this mistake. His premises are distinct from his conclusion, even though they don’t support it well.

B
relies inappropriately on expert testimony

The media consultant doesn’t mention any experts at all, so he can’t inappropriately rely on their testimony.

C
presupposes that just because something can happen it will happen

The media consultant concludes that traditional schools will be eliminated, but he doesn’t do so on the basis that they can be eliminated. In fact, he never actually proves that they can be eliminated. So, (C) can’t describe the flaw in his argument.

D
mistakes something that enables an institution to arise for something necessary to the institution

The media consultant assumes that just because books enabled traditional schools to arise, they must be necessary to traditional schools. But maybe these schools can carry on just fine, even though electronic media are fulfilling the role of books in communicating information.

E
confuses the value of an institution with the medium by which it operates

The media consultant never makes any claims about the value of traditional schools.

Psychologist: The obligation to express gratitude cannot be fulfilled anonymously. However much society may have changed over the centuries, human psychology is still driven primarily by personal interaction. Thus, the important social function of positively reinforcing those behaviors that have beneficial consequences for others can be served only if the benefactor knows the source of the gratitude.

Summarize Argument
You can't fulfill the obligation to express gratitude anonymously. Human psychology is still primarily influenced by personal interaction, so to positively reinforce generous behavior, the person being thanked needs to know who is expressing the thanks.

Identify Argument Part
The stimulus text refers to the main conclusion of the argument: the obligation to express gratitude can’t be fulfilled anonymously because a person’s generous behavior will only be positively reinforced if the person knows who is expressing the thanks.

A
It is an illustration of a premise that is used to support the argument’s conclusion.
The claim is the overall conclusion. It does not support any other statement in the stimulus, so it cannot be an illustration of a premise in the argument.
B
It is used to counter a consideration that might be taken to undermine the argument’s conclusion.
The claim is the overall conclusion. This answer describes a premise, which would support the conclusion by anticipating and refuting an attack on it. Since the stimulus text is the conclusion, it cannot be a premise of the argument.
C
It is used to support indirectly a claim that the argument in turn uses to support directly the conclusion.
The stimulus text is the overall conclusion. It does not support any other statement in the stimulus, so it cannot be either direct or indirect support for another claim.
D
It is used to identify the social benefit with which the argument is concerned.
The stimulus text is the overall conclusion. The argument focuses on reinforcing generous behavior, which benefits society. However, this benefit is mentioned in a premise as a reason why the obligation to express gratitude cannot be fulfilled anonymously.
E
It is the conclusion that the argument is intended to support.
This describes the role of the first sentence in the overall argument. The psychologist begins with her conclusion and spends the rest of the stimulus explaining how she reached that conclusion.
