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.

Topic: Buying Food
One day, I quickly ran to the market to grab some grub(food). I slowly grabbed the bag of chips from the isles and happily skipped to the counter. The cashier quietly awaited for the payment. I furiously looked into my pockets for my money. Quickly scattering my pockets I've come to noticed I had no money. I quickly raced outside the door, throwing the food on the floor. I sadly cried thinking how i lost my money.
Hope this helps, made it on the spot :)
