Explanation:
Scout takes Boo—“Mr. Arthur”—down to the porch, and they sit in shadow listening to Atticus and Heck Tate argue. Heck insists on calling the death an accident, but Atticus, thinking that Jem killed Bob Ewell, doesn't want his son protected from the law
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.
I'm not sure if there were specific answer choices but using complex words actually makes your statement rather unclear, especially assuming they are words the average person wouldn't know or understand.
