Read the excerpt from the code book.

by this stage, sending a pgp encrypted message is becoming quite complicated. the idea cipher is being used to encrypt the message, rsa is being used to encrypt the idea key, and another stage of encryption has to be incorporated if a digital signature is required. however, zimmermann developed his product in such a way that it would do everything automatically, so that alice and bob would not have to worry about the mathematics. to send a message to bob, alice would simply write her e-mail and select the pgp option from a menu on her computer screen. next she would type in bob's name, then pgp would find bob's public key and automatically perform all the encryption. at the same time pgp would do the necessary jiggery-pokery required to digitally sign the message. upon receiving the encrypted message, bob would select the pgp option, and pgp would decrypt the message and verify the author. nothing in pgp was original—diffie and hellman had already thought of digital signatures and other cryptographers had used a combination of symmetric and asymmetric ciphers to speed up encryption—but zimmermann was the first to put everything together in one easy-to-use encryption product, which was efficient enough to run on a moderately sized personal computer.

which sentence is most relevant to the argument that zimmermann’s pgp was easy to use?

The sentence that is most relevant to the argument that Zimmermann's PGP was easy to use is "To send a message to Bob, Alice would simply write her e-mail and select the PGP option from a menu on her computer screen".

The element that most clearly indicates that this sentence supports the argument that Zimmermann's PGP was easy to use is the word  "simply", which is used to refer to something that can be done in an easy way since it does not require to follow many steps. PGP stands for Pretty Good Privacy, an encryption program mainly used for encrypting or decrypting different types of files. PGP was created by Zimmerman in 1991.

the first proposition is to question economic materialism and victorian christianity. the lines are:

“it moves us not.—great god! i'd rather be

a pagan suckled in a creed outworn; ”

wordsworth is stating that nature no longer interests mankind, that the latter is not “moved” by it and explains that ancient western paganism had a more positive attitude concerning nature since it lacked the perv erted judaeo-christian interpretation of having received the world and all its animals and elements from god to use as we , instead of humans actually being not only part of nature but its wardens, meant to appreciate it and protect it.

the next lines are:

“so might i, standing on this pleasant lea,

have glimpses that would make me less forlorn;

have sight of proteus coming from the sea;

or hear old triton blow his wreathed horn.”

wordsworth here make it very clear that by actually looking and contemplating nature, human beings would reconnect with happiness, serenity and purpose. the use of mythological figures is quite evocative as well, proteus is a greek mythological god of the changing sea. he personifies the sea that changes, which symbolizes the way nature changes and inevitably can change to be destructive not only due to natural causes but to human pollution. furthermore, the sea is even more symbolic since all life originated in the sea so it is not only our past but our future since no life form in our planet can survive without water and if all water is destroyed in earth all life will be gone as well.

he then uses triton which is symbolic of the synthesis of both nature and mankind. triton is a mythological greek god that has the upper body of a man and the lower body of a fish (a merman). this human fish duality evokes the fact that humans are not only human but also part of nature, the fish tail representing nature. the main attribute of this god was that he used a conch shell as a horn to calm the roaring seas. in other words, triton uses nature through science for the benefit of human sailors who risk death during tempests. with the use of such metaphor, wordworth is conveying the message that human technology   is supposed to use nature to preserve nature and thereby humanity as well.

b. vast setting

explanation:

an epic is a poem of heroic proportions; it can't be short or focus on simple daily life event. it cannot be written with a casual tone as it narrates some heroic deeds of legendary figures.
