People that are well-informed know that Bordeaux is a French region whose most famous export is the wine [highlight]which[/highlight] bears its name.
Well-informed people know that Bordeaux is a French region whose most famous export is the wine [highlight]that[/highlight] bears its name.
I do get the corrections in the first part of the sentence, the only part I have problems with is the "...which bears its name". Can anybody explain to me why I can't use which here?
Thanks in advance,
which must used for non essential modifier and that must be used for essential modifiers if we see which in the sentence then there must be a comma before it to make it correct and if we see a which without a comma then in gmat it's always wrong and we must check that in the given sentence we should use essential modifier or non essential modifier so if we remove a non essential modifier then it should not change the meaning of the sentence if we remove the essential modifier then the meaning is changed so in the sentence above

we can avoid which for two reasons 1. we can't see a comma before which so we should not use which here and 2.if we remove which then we feel something must exist between wine and bears so if we feels like that we must insert that, which makes it correct.
