The SC GUIDE mentions the following idiom as SUSPECT :
We adopted new policies, THE AIM OF WHICH was TO REDUCE theft.
here, what does WHICH refer to ?
Is it the 'adoption of new policies'. I recall reading in the PRONOUNS chapter that WHICH cannot be used to refer ideas in an earlier clause.
or
Is it the policies ? In that case WERE should be used instead of WAS.
Please clarify.
