At many electronics retail stores, the consumer has the option of purchasing product warranties that extend beyond the manufacturer' s warranty. However, consumers are generally better off not buying extended warranties. Most problems with electronic goods occur within the period covered by the manufacturer' s warranty. Which one of the following, if true, most strengthens the argument? ['Most of those who buy extended warranties on electronic goods do so because special circumstances make their item more likely to break than is usually the case.', 'Retail stores sell extended warranties in part because consumers who purchase them are likely to purchase other products from the same store.', "Problems with electronic goods that occur after the manufacturer's warranty expires are generally inexpensive to fix in comparison with the cost of an extended warranty.", "Some extended warranties on electronic goods cover the product for the period covered by the manufacturer's warranty as well as subsequent years."]
