The passage is mainly about

选项 A、the harmful effect of vitamin A.
B、vitamin A and fractures.
C、vitamin A and human health.
D、vitamin A deficiency.

答案B

解析主旨题。纵观全文，文章主要围绕vitamin A和fracture的关系展开论述，这两个词也是在整篇文章中复现率最高的词。由此可知"维生素A和骨折"符合文意。"维生素A的有害作用"过于宽泛；"维生素A和人类健康"更是把主题人为地拔高，涵盖面过大；"维生素A的缺乏"是文中的一个细节，不能作为主旨。
