Question

Parents should give teenagers chances to make their own decisions. For example, the ________ should be allowed to get their ears pierced.

A.sixteen-year-old B.sixteen-year-olds C.sixteen-years-old

Answer

B

【解析】

句意：父母应该给青少年自己做决定的机会。例如，应该允许16岁的青少年穿耳洞。

考查名词复数及年龄段表达。 sixteen-year-old 16岁的，是形容词，应该修饰名词；也可以作名词，代指16岁的青少年，是单数形式；sixteen-year-olds是复数形式，指16岁的青少年们；sixteen-years-old形式错误，在合成形容词中，year应用单数形式。根据句意可知，这里应用复数形式，故选B。
