【正确答案】 A

【答案解析】[理由] 比较级连接词如that(比……)或as(一如……)所引导的状语从句，其结构须与之前的主句结构相同，换言之，主句的结构若是“主语+be动词”时，as或than引导的状语从句结构也须为“主语+be动词”；主句若有助动词(can、will...等)时，as或than引导的状语从句也要有助动词；主句若有一般动词时，as或than引导的副词从句必须按照主语人称及动词时态分别使用do、does、did。
1)有be动词时：
[例] He is more diligent than you (are).
(他比你勤奋。)
He is as diligent as you (are).
(他和你一样勤奋。)
2) 有助动词时：
[例] He can sing much better than you (can).
(他唱歌比你好听。)
He can sing as well as you(can).
(他唱歌跟你一样好听。)
3) 有一般动词时：
[例] He studied harder than you (did) last year.
(他去年比你用功。)
He studied as hard as you(did) last year.
(他去年和你一样用功。)
根据上述，原句空格前有“…is not enforced…”，故知as引导的结构也要置入be动词is，使结构一致，因此(A)应为正选。
...as it is in the film industry and music industry.
=...as it is (enforced)in the film industry and music industry.
……像在电影业和音乐界般地被强制执行。
