Advertisement: At most jewelry stores, the person assessing the diamond is the person
selling it so you can see why an assessor might say that a diamond is of higher quality than it
really is. But because all diamonds sold at Gem World are certified in writing, you’re
assured of a fair price when purchasing a diamond from Gem World. The reasoning in the
advertisement would be most strengthened if which one of the following were true?
a) Many jewelry stores other than Gem World also provide written certification of the quality
of their diamonds.
b) The certifications of diamonds at Gem World are written by people with years of experience
in appraising gems.
c) The diamonds sold at Gem World are generally of higher quality than those sold at other
jewelry stores.
d) The diamond market is so volatile that prices of the most expensive diamonds can change by
hundreds of dollars from one day to the next.
e) The written certifications of diamonds at Gem World are provided by an independent
company of gem specialists.

a) Many jewelry stores other than Gem World also provide written certification of the quality of their diamonds. - If other stores also provide written certification, then it can be assumed that they too provide a fair price - Weakens the arguement - Incorrect
b) The certifications of diamonds at Gem World are written by people with years of experience in appraising gems. - Still the assesser and seller would be the same person and there is no proof that they are offering a fair price - Weakens the arguement - Incorrect
c) The diamonds sold at Gem World are generally of higher quality than those sold at other jewelry stores. - Neither weakens not strengthens the arguement - Incorrect
d) The diamond market is so volatile that prices of the most expensive diamonds can change by hundreds of dollars from one day to the next. - Irrelevant info - Incorrect
e) The written certifications of diamonds at Gem World are provided by an independent company of gem specialists. - Since the assesser and seller are different people, the price offered would be based on the quality of the diamond - Correct
