[求助]OG 1-2

OG的一篇的第二题：The passage suggests that Jarvis's work has called into question which of the following explanatory variables for naked mole rat behavior? 答案为什么是B。 

想明白了，自己解释一下：做错的原因是没有看懂题干。

题干的意思应该是：这篇文章表明J的著作对下面那种naked mole rate的行为变化提出了质疑。关键词：call into question---产生问题----质疑。

这样就定位到了regardless of its age, 所以选B
