问题     The "Karat" marking on jewelry tells you what proportion of gold is mixed with other metals. If 14 parts of gold are mixed with 10 parts of base metal, the combination is called 14 Karat (14K) gold. The higher the Karat rating, the higher the proportion of gold in the object. The lowest Karat gold that can be marketed in the United States is 10-Karat gold. Jewelry does not have to be marked with its Karat quality, but most of it is. If there is a Karat quality mark, next to it must be the U.S. registered trademark of the person or company that will stand behind the mark, as required by the National Gold and Silver Stamping Act. [br] This paragraph serves the consumer as ______.
选项 A、important buying information
B、a challenge to buy more gold
C、a debate over gold prices
D、advice about buying silver
答案 A
解析 本段的主要内容是介绍了K/开的含义，及黄金饰品上应有的标识，因此可推断出它为消费者提供了重要的购买信息。本题也可用排除法做，选项B．“本段为消费者提供了购买更多黄金的挑战。”C．“本段为消费者提供了有关黄金价格的思考。”D．“本段为消费者提供了购买银器的建议。”均不符文中之意。
