Question

This bootleg wallet, on casual inspection, looks just like my friend Bob’s authentic Ridge wallet. They feel alike too; they’re about the same weight and the surface of the leather is equally smooth. Bob could sell his wallet for $200 dollars on Craig’s List so I could probably sell the bootleg wallet for about the same amount. The stitching clasps, zippers, and other details are slightly sloppier on the knock-off, but Bob's wallet has minor imperfections too.

Which of the following is the best challenge to the strength (or reliability) of the argument above

a. It would be immoral to sell a known knockoff as if it were an authentic item. (By the way, this is true whether or not it is the correct answer.)

b. There are important, numerous dissimilarities between the knockoff and the authentic wallet; a close inspection, which the buyer of a $200 wallet might require, would reveal the dissimilarities in detail and craftsmanship.

c. It is possible for the argument to have all true premises and a false conclusion.

d. Bob could not sell his used wallet for $200, even if it is authentic.  

e. The sample is too small. One wallet is not a large enough sample to justify the conclusion about all bootleg wallets.

Answer 1

The answer is b.

There are important, numerous dissimilarities between the knockoff and the authentic wallet; a close inspection, which the buyer of a $200 wallet might require, would reveal the dissimilarities in detail and craftsmanship because he carefully measure the product quality.
