Colorless diamonds can command high prices as gemstones. a type of less valuable diamonds can be treated to remove all color. only sophisticated tests can distinguish such treated diamonds from naturally colorless ones. however, only 2 percent of diamonds mined are of the colored type that can be successfully treated, and many of those are of insufficient quality to make the treatment worthwhile. surely, therefore, the vast majority of colorless diamonds sold by jewelers are naturally colorless.
a serious flaw in the reasoning of the argument is that
(a) comparisons between the price diamonds command as gemstones and their value for other uses are omitted
(b) information about the rarity of treated diamonds is not combined with information about the rarity of naturally colorless, gemstone diamonds
(c) the possibility that colored diamonds might be used as gemstones, even without having been treated, is ignored
(d) the currently available method for making colorless diamonds from colored ones is treated as though it were the only possible method for doing so
(e) the difficulty that a customer of a jeweler would have in distinguishing a naturally colorless diamond from treated one is not taken into account

In the 1970s, kmart used blue light specials to encourage customers to flock to a particular department having a temporary sale. a spinning blue light activated for approximately 30 seconds, and then an in-store announcement informed shoppers of the special savings in the specific department. over time, loyal kmart shoppers learned to flock to the department with the spinning blue light before any announcement of special savings occurred. if kmart was employing classical conditioning techniques, what role did the spinning blue light play?
