the time they stopped working together, they more albums than band in history.
A. By; had sold; any other
B. At; had sold; any
C. In; have sold; all
D. For; had sold; all the other
答案：
(答案→)A. By; had sold; any other
B. At; had sold; any
C. In; have sold; all
D. For; had sold; all the other
解析：考查时态和比较级。By+过去的时间，从句用过去完成时；by+将来的时间，从句用将来完成时。根据stopped可知，是过去的时间，应该用过去完成时，排除C；by the time...意为“到......时候”。any other“任何其他的”，用于同一范围的比较。故选A。
