一題輔導班給的答案 不解

2008gmat770

South America countries have amassed $1,000 billion in debts; at stakes, should a significant number of these debts be repuidiated, is the solvency of many American and Japanese banks

A. should a significant number of these debts be repuidiated, is

B. should a significant number of these debts be repuidiated, are

輔導班給的答案是A, 但是a number of 不是代表"多數"?...後面應該用 are嗎?

我试着答一下啊　不对的地方望各位ＮＮ指正～

should 此处表示一种可能性不大的语气　本应像ＬＳ说的那样　a significant number of these debts should be...　而且这个should可以提到前面来

这个句子的正确语序应该是 should a significant number of these debts be repuidiated, the solvency of many American and Japanese banks is at stakes. 所以　此处用单数的is  因为主语是solvency(清偿能力）
