Explanation:
In <em>The Raven</em>, the speaker is dealing with a recent death of Lenore, a woman he loved. One night, he is visited by an unusual guest, the raven that can speak. The raven, however, only utters one word - <em>"Nevemore".</em>
In this excerpt, the speaker is deeply distraught and orders the raven to leave. He wants the bird to return to the storm and leave its perch on the bust of Pallas above his door. The speaker, moreover, wants to be alone and to deal with his loss all by himself. He does not need companion at this point, especially not this supernatural creature that responds to every question with the same, not so promising word.
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.
According to the Scientific Method, in order to make a controlled experiment you NEED to have an hypothesis.
A controlled experiment consists of a test done by a scientist in which only one or a few variables are changed while the others remain constant in order to prove or disprove a hypothesis. This hypothesis is key to said experiment because it provides the starting point from which the professional can begin the procedure, as it helps focus on the subject that one is trying to get results from. Without a clear hypothesis, the outcome of the experimentation will not be valid nor specific.
