答楼主：
OG 对这道题原句的解释是：
In this sentence, the there are … that …
construction contributes nothing more than
unnecessary words. The sentence needs to make
clear whether provisions or code is the subject of
the main verb stimulated.

OG解释的意思是要分清主语是哪个，而不是说让code成为主语。provision也可以是主语，只是选项里没有以provision为主语的正确句子
