单项选择题
Homeostasis refers to any process, such as negative feedback, that living things employ to maintain stable conditions indispensable for survival, and which arises from balances between forces and factors mutually influencing each other. Disturbance, or departure from equilibrium is of more consequence than negative feedback: systems cannot correct themselves without straying. A car and its driver, for instance, can be regarded as a homeostatic system seeking to keep the car moving on track. Thus, if the car skids, the driver automatically responds by quickly steering the wheel in the opposite direction, but such abrupt negative feedback usually overcorrects. Likewise, if the magnitude of correction is commensurate with the disturbance that triggered it, the correction may become an impressed change in the direction opposite to that of the original disturbance. Each feedback is of lesser magnitude than the last, so that as the oscillations of the system dampen, negative feedback achieves its goal in both artificial and natural systems.
It may be inferred that to attain greater positive feedback, in the case of the skidding car, the driver should do which of the following（） A．Keep turning the wheel in the original direction.
B．Turn the wheel in the opposite direction.
C．Turn the wheel in the opposite direction, then turn it back to the original direction.
D．Keep turning the wheel in the original direction, then back to the opposite direction.
E．Allow the wheel to turn freely.
