单选题 In practice ,what is the most important feature that makes an object an antique?

A、 It has to be 100 years old.
B、 It has to be at least 200 years old.
C、 It has to be beautiful and decorative.
D、 It has to have aesthetic or historic value.

【正确答案】 D

【答案解析】细节理解题第一段第三句指出“…an antique must also be distinguished by some degree of aesthetic or historic merit”，即古董必须有一定的美学价值和历史价值。A)、B)不对，因为虽然有法律的规定，但是很难单纯用年代来界定是否是古董；C)的观点太片面。虽然第一段提及了“An antique is usually both beautiful and decorative”，但这是通常的现象，不是判断的标准。
