Choice A is ambiguous: it can be taken to mean either (1) that NONE of the proceedings were carried live or (2) that NOT ALL of them were. Given the second part of the sentence (Soviet audiences saw a lot of the conference), (1) is absurd, but that doesn't stop choice A from potentially carrying both meanings. Remember that, even if 'common sense' or 'process of elimination' can get rid of ambiguity, it's still ambiguity, and it's still a problem.
Here's a simpler analogy:
'All of my friends weren't at the prom.'
could mean (1) all of my friends were absent from the prom
could mean (2) at least one of my friends stayed home
We can't tell.
Choice E resolves the ambiguity.
