PrepTest 77, Section 3, Question 23
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?
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.
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.
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.
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.
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.
