OA: E

I was confused between A and B, and came up with answer A. Can anyone explain what's wrong with A or why is B is prefered to A?

"Although" calls for contrast, and the placement of "not" is better in E than A.

So, are A and B grammatically incorrect?

In my understanding, "not" in E is to put the focus on "all the proceedings of the Communist party conference",
and "not" in A&B put their stresses on "were carried live" . Is that why E is prefered to A and B?

Correct me if I misunderstand.

"All the M&M's are not purple."

"Not all the M&M's are purple."

Which one would you pick? Personally I would prefer the second one over the first. I don't know if A is grammatically incorrect, but it just doesn't sound right.

Come to think of it, the first choice would almost mean that none of the M&M's are purple, and thus alters the meaning of the expression.

IMO the correct answer is E.
