The correct answer is D) In a recent study, shoppers who had recently purchased a garment in a luxury material cited similar reasons for buying angora as buying cashmere. This option best supports the claim that more people will be buying angora clothing.
Explanation
The Argument's Core: The argument states that a reduction in cashmere supply has driven up its price. The conclusion is that more people will buy angora. This relies on the unstated premise that angora is a suitable substitute for cashmere, and that the rising price of cashmere will directly lead consumers to switch to angora.
Why D is the Best Support: Option D strengthens this link by showing a direct consumer preference connection. If consumers have similar reasons for buying both angora and cashmere, it suggests they see the two materials as interchangeable for meeting their needs or desires for luxury. Therefore, a sharp price increase in one would logically lead them to switch to the other, which is the main premise of the argument. It provides a direct reason for the consumer behavior shift predicted by the conclusion.
Why the Other Options are Incorrect:
A) Any disease that affects a bovid such as the cashmere goat is unlikely to cross the biological order line and affect lagomorphs such as the angora rabbit. This is an irrelevant fact. It confirms the supply of angora won't be affected by the disease, which is already a given assumption, but it doesn't explain *why* consumers would switch from cashmere to angora.
B) Most consumers cannot tell the difference between cashmere and angora, which are both expensive and similar in texture. While this might seem plausible, it's not as strong as D. The fact that consumers can't tell the difference doesn't necessarily mean they'll switch. They might simply choose a non-luxury item, or just buy less. Option D directly addresses the *reason* for the purchase, which is what the conclusion is built on.
C) When the price of one luxury item sharply rises, many other luxury items see a slight increase in price. This weakens the argument. If the price of angora also increases, it makes it less likely that consumers will switch to it as a cheaper alternative.
E) The sales of luxury items are far less sensitive to price fluctuations than are most inexpensive staple items. This also weakens the argument. If luxury item sales are not very sensitive to price changes, then the sharp rise in cashmere prices might not significantly reduce its sales. Consequently, there would be less reason for consumers to seek out a substitute like angora.
