We can learn from the text that
High concentration of vitamin A may lead to fracture because
选项
A、elderly people are slow in digesting vitamin A.
B、the absorption of excessive vitamin A makes people near-sighted.
C、it helps produce cells that weaken the bones of human beings,
D、vitamin A stays in human body for a long timid.
答案
C
解析
细节题。文章第七段最后一句话提到"动物研究表明,过量的维生素A可以促进溶骨细胞的形成",这就解释了过量维生素A引起骨折的原因。因此,"它有助于形成削弱骨骼的细胞"符合文意。"老年人消化维生素A的速度慢","吸收过量维生素A使人近视"和"维生素A在人体内存留时间长"均与原文不符。
