18. Stable interest rates on long-term bonds are the financial market's vote of confidence in the Federal Reserve keeping in control of inflation. (A) in the Federal Reserve keeping in control of inflation (B) that the Federal Reserve will keep inflation under control (C) for the Federal Reserve, that it would keep control of inflation (D) that inflation will be kept control of by the Federal Reserve (E) that inflation would be kept control of by the Federal Reserve 就是觉得confidence后面应该有个介词,所以选了A,但答案是B.认同control地用法 但我觉得两害取其轻,还是A好。想请教牛牛的意见
