Answer 1

In the Question it is mentioned that CAESAR cipher is used. But trying all possibilities of Caesar shifts (i.e 1 to 26) haven't give any meaningful plaintexts.However Considering the given ciphertext as substitution cipher I was able to decrypt the given Ciphertext to Plaintext ::

CARPENTER THEY THANKED HIM MUCH FOR THAT

A LOAF OF BREAD THE WALRUS SAID
IS WHAT WE CHIEFLY NEED PEPPER AND VINEGAR

BESIDES ARE VERY GOOD INDEED
NOW IF YOU RE READY OYSTERS DEAR WE CAN BEGIN TO RE OUT OF BREATH AND ALL OF US ARE FAT NO HURRY SAID

I have added spaces for more readability of the plaintext message.

substitution key:

ciphertext :: qgzafolbvskjywtcmhxpduerin

plaintext :: abcdefghijklmnopqrstuvwxyz

Above Substitution key imply's that each character in ciphertext line maps to the character right below in plaintext.

for eg, if q is in ciphertext then corresponding character in plaintext is a.

So, steps to produce the plaintext from ciphertext is to replace every character in ciphertext with corresponding character

Using the above given mapping(key).

If you have any doubts, I will always be happy to clarify them. Just mention in comment section.
