For a computer to be intelligent, it must possess at least one of three qualities: creativity, self-awareness, or the ability to learn from its mistakes. Because the AR3000 is not creative or self-aware, it must have the ability to learn from its mistakes if it is intelligent.

Which one of the following arguments is most similar in its reasoning to the argument above?

A. Every vaccine is either an attenuated-virus vaccine, a dead-virus vaccine, or a pure DNA vaccine. Vaccine X cannot fall into the last two categories, because it contains living viral cells. Therefore, vaccine X must be an attenuated-virus vaccine.

B. Every commonly used vaccine is either a dead-virus vaccine, an attenuated-virus vaccine, or a pure DNA vaccine. Vaccine X is not a dead- or attenuated-virus vaccine. Therefore, if it is a commonly used vaccine, it must be a pure DNA vaccine.

C. Every vaccine is either a dead-virus vaccine, an attenuated-virus vaccine, or a pure DNA vaccine. Thus, if vaccine X is not a dead- or attenuated-virus vaccine, it must be a pure DNA vaccine.

D. Every commonly used vaccine is either a dead- virus vaccine, an attenuated-virus vaccine, or a pure DNA vaccine. Vaccine X stimulates the production of killer T cells in the immune system, unlike any pure DNA vaccine. Therefore, if it is not a dead-virus vaccine, then it must be an attenuated-virus vaccine.

E. Every commonly used vaccine is either a dead- virus vaccine, an attenuated-virus vaccine, or a pure DNA vaccine. Because vaccine X is not an attenuated-virus vaccine,it must be a pure DNA vaccine if it is not a dead-virus vaccine.

Break It Down -
Computer --->Intelligent --> at least one of 3 qualities: creativity, self-awareness, or the ability to learn from its mistakes.
AR3000 --> not creative or self-aware --> ability to learn from its mistakes - If intelligent.

This structure is matched only by answer choice B.

B. Every commonly used vaccine is either a dead-virus vaccine, an attenuated-virus vaccine, or a pure DNA vaccine. Vaccine X is not a dead- or attenuated-virus vaccine. Therefore, if it is a commonly used vaccine, it must be a pure DNA vaccine.

This is a good argument. Here’s the structure:

[AR3000] is a type of [computer]
For [computers], there are three ways to be [intelligent]: [creativity, self-awareness, learn from mistakes]
The [individual computer] is not [two of the three types of intelligent] So if the [individual computer] is [intelligent], then it is [the third type]
The bracket terms are the key points. The right answer exactly matches this structure. The wrong answers fail in one or more points.

In practice, I skimmed the answers looking for differences. The most common difference was that almost all the wrong answers said “vaccine X is one of the three types of vaccine”. That’s as if the stimulus said “the AR3000 is one of the three types of computer intelligence”.

That’s totally wrong. The stimulus wasn’t saying the AR3000 was intelligent. It was saying that if the AR3000 was intelligent, then it had a certain one of the three necessary conditions. The analogue in the right answer is saying “if vaccine X is a commonly used vaccine.”

Honestly, that’s all there is to explain about the wrong answers. Beyond that major error, the answers just combine the same terms in different ways. But they’re all wrong because they don’t say “If vaccine X is a commonly used vaccine, then….”

___________

This says that vaccine X is a vaccine. The stimulus was about whether AR3000 was intelligent.
CORRECT. This matches. The facts below fit exactly into the structure from the analysis above.
1. [Vaccine X] is a type of [vaccine]
2. For [vaccines], there are three ways to be [commonly used vaccines]: [dead virus, attenuated virus, pure DNA]
3. The [individual vaccine] is not [two of the three types of commonly used vaccine] So if the [individual vaccine] is [commonly used], then it is [the third type]
This says that vaccine X is a vaccine. The stimulus was about whether AR3000 was intelligent.
