这道题答案不是C吗？
increased 和more then doubled重复肯定错。排除A,B.
since then明显是现在完成时的时间状语，我认为D,E不对。
E中since then把its circulation 和its advertising分开显然不好。
讨论。

我一看到这题错选了D。后来分析是对since作adv.的用法不甚了解造成的。
从m-v中摘了一段：
since adv.
1 : from a definite past time until now
2 : before the present time : AGO
3 : after a time in the past : SUBSEQUENTLY
这里c选项中since是第3种用法，since用于现在完成时态。
