Research has shown that shoppers who purchase garments in a "luxury" material, such as cashmere or angora, are likely to purchase garments in more than one other luxury materials, as well. A recent livestock disease has significantly reduced the amount of cashmere available on the market. This, in turn, has driven up the prices of the cashmere products still available for purchase. We can ttherefore conclude that more people will be buying angora items of clothing this year than they did in previous years. Which of the following, if true, best supports the claim that more people will be buying angora clothing this year? ['The number of customers purchasing angora has increased every year for the past decade in steady increments.', 'In a recent study, shoppers who had recently purchased a garment in a luxury material cited similar reasons for buying angora as buying cashmere.', 'Most consumers cannot tell the difference between cashmere and angora, which are both expensive and similar in texture.', 'The same disease that affected the livestock producing cashmere has also affected the farms that produce angora.']
