A. as long as一般作 “只要”的意思,在这里是正解
as long as everything goes well, you should get them.
只要一切都没问题,你就能得到.
B. as far as一般有如下意思：
(1) as far as 远至, 到...程度, 尽可能
例: I will help you as far as I can
我会尽可能的帮助你.
(2) as far as ...be concerned 就...而言 (和 be concerned 搭配有此意)
例：As far as oil energy is concerned, we cannot be too frugal.
就石油能源而言,我们愈节省愈好.
所以as far as在这里即使灵活运用也不能令句子通顺.
