我查過LONGMAN 也沒有看到這樣的用法
想請教大家，要如何使用 have/ has since.....

314. Founded in 1983, the magazine increased its circulation more than double since then, and its advertising.
(A) increased its circulation more than double since then,
(B) has since increased its circulation more than double,
(C) has since more than doubled its circulation
(D) since then more than doubled its circulation
(E) more than doubled its circulation since then

這裡的since應該是adv,通常也用於完成式

Macmillan字典:

She left home in 1933 and hasn't been seen since.
The accident was blamed on the pilot, who has since retired.
