12. GWD26-Q12
The most vexing problem faced by researchers exploring wind-powered generation of electricity is achieving a constant flow of power from an unpredictable natural source that meets demand, but so the flow does not overload electrical grids with sudden voltage increases

A. achieving a constant flow of power from an unpredictable natural source that meets demand, but so the flow does not overload
B. achieving a constant flow of power from an
unpredictable natural source, which meets demand but without overloading
C. how to achieve a constant flow of power
from an unpredictable natural source, a flow that meets demand but does not overload
D. how to achieve a constant flow of power
from an unpredictable natural source, but
a flow that meets demand without overloading
E. how a constant flow of power from an unpredictable natural source can be achieved, which
meets demand but does not overload
答案是C， A哪里错了？

that就近修饰natural source错
but前后也不平行

The problem is how to achieve flow......., a flow.
perfectly explained the flow.
A is wrong because "but so" is not correct.

我从语义上快速直接排除了AB
因为vexing problem is achieving a constant...意思是不对的
不能说最烦人的问题是获得（了）一个稳定的...
加一个not意思才稍微顺点——最烦人的问题是不能获得一个稳定的...
当然how to是最好的——最烦人的问题是如何获得一个稳定的...
不知道我的理解对不对
