some questions..
"In fact, this show has been criticized for the racial imbalance problem until this reorganization."
"In fact, before this reorganization the show had been criticized for its problem with racial imbalance."
1)As I know, the word "until" has the meaning of continuous action. Why should "until" be "before"?
2)Don't you say "noun + problem" like "the racial imbalance problem"?
3)What's the difference between "problem with" and "problem about"?
Help me please!
