If a ring is stamped 24K, it has ______.
A.204 parts of gold
B.24 parts of gold
C.two and four-tenths parts of gold
D.10 parts of gold
参考答案:B
解析:[分析] 推断题型。 见文中第二句:If 14 parts of gold are mixed with 10 parts of base metal,the combination is called 14-Karat(14K)gold.如果将14份黄金与10份普通金属混合,它们的化合物即14K金。由此可推论24K金应为24份黄金与10份普通金属混合。所以选项B.“如果一只戒指上刻24K,它应含有24份黄金。”是答案。
