问题 Research of Vitamin A has been conducted on human bodies since 1912.

It was not until McCollum and Davis undertook a series of experiments on rats from 1912 to 1914 that vitamin A was described for the first time.

选项 A、True
B、False

答案 B

解析事实细节的找寻与判断。原文中“experiments on rats”表明维生素A是在老鼠实验中得到首次描述的，并且实验时间段为1912到1914年。题干中所述，即自1912年起维生素A就已经在人体中进行研究，与原文对照，此陈述不合理。因此，该题的说法是错误的。
