The poet Ampleforth is the character who was surprisingly thrown in the cell with Winston, the main character.
The surprise isn't really that the poet was jailed, but that he ended up in the same cell as Winston, after all, he had been slipping forbiden words into his poem's "translations" before, a very punishable offense.
I think the questions that must be ask are:
a.What does “encryption” mean?
d.What are “key distribution problems”?
All the text is based on the concept "encryption" so it is very important to know what it means in order to undestand the rest of the information. If not, you will be missing important facts. In addition, there are a lot of words used that are derived from this one, so you won't be able to undestand them.
Another important concept that gives a lot of information just by knowing it's meaning is "key distribution problems", they could be two or a thousand, it is important to know what they are and what they do.
The other question that seems important is the one of the "public key cryphtography" but this one can be inferred by the context.
