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:
Explanation:
1. A declarative sentence:
- <u>I wake up early in the morning every day. </u>
It is just stating an idea or fact.
2. An imperative sentence.
- <u>Hand me the some bread.</u>
The sentence is making a request.
3. An interrogative sentence.
- <u>Can you leave me at the bus station, because I am late?</u>
This sentence is asking a question, thus it ends in a question mark. See that the verbs "can" and "am" are both in present tense, then they are consistent.
4. An exclamatory sentence.
- <u>Watch out for the car that stopped abruptly!</u>
You are conveying a strong feeling of urgency. The exclamatory sentences end with the exclamation mark: !
A further explanation:
Verb tense consistency refers to not changing the tense throughout a clause. Switching from one tense to another is a syntax error, that makes the clauses weird or even unintelligible.
The answer to the question is D .
