我做了三遍了，还是错，我就不明白题目问的 The passage suggests that Jarvis's work has called into question which of the followin explanatory variables for naked mole rat behavior?是什么意思？
选项有四个， A. Size B. Age C. Reproductive status D. Rate of growth E. Previously exhibited behavior
lines 33-35: Jarvis posits that growth rate may affect how long any individual rat performs a task, regardless of its age. Thus, it can be inferred that the variable that Jarvis's work calls into question is age.
B: Jarvis's work tends to discount age as a determining factor in rat behavior.
D: Rate of growth is the factor that determines what tasks the rats do and for how long.
