The correct answer would be that all of the elements mentioned were part of St. Thomas Aquinas philosophical system. He considered himself an Aristotelian (followed Aristotle's teachings which in modern day are considered the development of Plato's teachings), an Empericist (it is the theory that all knowledge comes from sensory experiences) and a Neoplatonist ( believes mind over matter and that reality is subjective; depends on the highest principle). And since he was before anything a Christian theologian, then all the elements are part of his system.
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.
The answer is D. A declarative sentence simply makes a statement. It isn't seeking information and it always ends in a period.
The state of the area of the house of the ushers is very bad stating the condition of the usher themselves and that of the area. The day has been described as dark and dull. The trees are decaying and scary to look at, not cut from a long period of time.
<u>Explanation:</u>
The main thing in the story "The fall of the house of Ushers" is the house in which the Ushers used to live. The house has been described in a very bad condition by the narrator and in fact it has cracks also in it making it show that it is gloomy and very old.
The house is gloomy and mysterious. The narrator observes that the house seems to have absorbed an evil and diseased atmosphere from the decaying trees and murky ponds around it. Along with that the area surrounding the house is also the same as the house.
