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.
Answer:
In my opinion is They are just as curious about the fishermen as the fishermen are about them.
Explanation:
The texts says they're rescued then captivated but the sailors haven't done anything to them other than rescuing them from the island.
There is nothing relevant about suspicious creatures in the text.
Nowhere in the provided text there is said that the sailors are gonna do smth bad to the rescued ones. Nor there is a dialog between the sailors about the captives.
Whilst on line 16 till end the sailors and the rescued ppl glance at each other when they think the other one is not looking. Giving the idea of curiosity from both sides. (that's all I could see from the provided text. Hope it helps)
