Summarize Argument
The author concludes that changes to library classification systems are a scheme used by publishers to increase sales. The author supports this statement by stating that the new books that fit into the new classification system are expensive, and the only way to get someone to buy them is to convince them they need the latest classification system.
Identify and Describe Flaw
This argument fails to link convincing buyers they need the new books with the conclusion that the new systems are simply money-making ploys. The author never said in the premises that the new systems provide no benefit to the buyer; each new generation of the system could be more useful to libraries than the last. If this were the case, then selling these new books to libraries would not be a ploy for more sales, because they would actually benefit the libraries.

The author does not provide support for this claim; however, that is not where he went wrong. Authors do not have to provide support for facts they state in premises—we just have to take their word for it.

The author never ruled out other motivations for the sellers of the systems, such as the possibility that they are sharing massive improvements in each new generation of the system. Instead, he concludes that the sellers are only in it to make more money.

The author never addresses alternate buyers of the systems, but this is not relevant to the argument. Our author is concerned with libraries and the motives of the system sellers toward libraries, not with any other potential customers.

This answer choice is descriptively inaccurate. The author’s conclusion is that the booksellers are trying to get money out of the libraries, and he never even mentions a need or lack thereof for a new system.

The author is not concerned with whether libraries can afford these books or not. He is instead concerned with the motives of the company that sells the new systems.
