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.
This is a personal question
The rhetorical devices that President Trump uses in this excerpt are options 3 and 5.
Trump uses overstatement in sentence number 5.
Overstatement is saying something to lay emphasis or give a profound meaning, as to make the point more important than it is. As a result, Trump uses overstatement when he puts emphasis on the word America.
Moreover, he uses repetition in sentences number 6 and 7.
Repetition is a rhetorical device in which the person repeats the same word or phrases several times, to make the idea more concrete or memorable. This device appears when Trump uses the word "protect" multiple times in his speech.

An index card can be defined as a small card (usually measuring 4 inches by 6 inches or 3 inches by 5 inches) that are used for recording informations, mostly in an alphabetical order. This card was developed in 1760 by Carl Linnaeus and is essentially suitable for presentations because they can be used to store discrete data such as addresses, notes, telephone numbers, etc.
Hence, using index cards will improve a presentation because they keep the presenter from reading the speech, as he would only have to look at the jotted points or piece of information.
