请教两个问题！

问题1：Never before in the history of music have musical superstars been able to command (so extraordinary fees as they are today).
a.so extraordinary fees as they are today
b.such extraordinary fees as they do taday
a错在哪里呢？不是有so adj n. 的用法么？而且，are后面省略了able to cammand应该也没有问题啊？是不是so...as的用法不对？只能有so....that?

问题2：Bob Wilber became S's student and protege when he was 19 and , for a few years in the 1940's, came as close to being a carbon copy of the jazz virtuoso in performance (as anyone has ever come)
a.as anyone has ever come
b.as anyone ever had been
c.as anyone ever had done
b,c错在哪里呢？为什么这里要用现在而不是过去完成时？come为什么不用done替换呢？
been后面省略close to...有问题么？

2。ever的位置不对，ever应该在has或者had后面
