问题     Long-suffering couples take heart. There is a good reason for those endless arguments in the front of the car: men and women use different parts of the brain when they try to find their way a-round, suggesting that the strategies they use might also be completely different.
    Matthias Riepe and his colleagues at the University of Ulm in Germany asked 24 healthy volunteers—half of them men, half women—to find their way out of three virtual-reality mazes displayed on video goggles. Meanwhile, the researchers monitored the volunteers’ brain activity using a functional magnetic resonance imaging(fMRI)scanner. This showed that men and women called on strikingly different brain areas to complete the task. "I didn’ t expect it to be so dramatic," says Riepe.
    Previous studies have been shown that women rely mainly on landmarks to find their way. Men use these cues too, but they also use geometric cues, such as the angle and shape of a wall or a corner. Such studies also suggest that men navigate their way out of unfamiliar spaces more quickly, as Riepe found in his study, too.
    Riepe discovered that both men and women used parts of the parietal cortex towards the top of the brain, the right side of the hippocampus and a few other well-established areas to find their way out. Neuroscientists think that the parietal regions help translate what the eyes see into information about where the body is in space, while the hippocampal region helps process how objects are arranged.
    But other regions seemed to be exclusively male or female. The men engaged the left side of their hippocampus, which the researchers say could help with assessing geometry or remembering whether they have already visited a location. The women, by contrast, recruited their right frontal cortex. Riepe says this may indicate that they were using their "working memory" , trying to keep in mind the landmarks they had passed.
    "It fits very well with the animal studies," says Riepe. He points out that there seem to be similar differences in rats. For example, damage to the frontal lobe will impair a female’ s sense of direction, but not a male’ s.
The reason for the differences in the sexes, according to Riepe, could be______.
选项 A、the environmental factor
B、the psychological factor
C、the innate factor
D、all of the above
答案C
解析 文中讲到Riepe发现在判断方向时男性和女性使用的大脑区域不一致，而且有些区域是男性或女性专有的，由此可知男性和女性之所以会不同是因为先天的因素，即先天产生的大脑区域不同。
