This is a personal question. I will answer below according to the word that was unfamiliar to me, but feel free to add to the answer in case there were more for you.
Answer and Explanation:
The word that I found unfamiliar and whose meaning I did not know at first was "behest". I had never seen that word before. To understand its meaning, I looked for context clues. <u>The rest of the sentence in which "behest" appears functions as a clue to finding its meaning. It says that, at a person's behest, something happened: "the Exhibition dropped its superfluous rags and stripped itself. . ." As soon as I read this part, it made me think of the word "command." For instance, the sentence "At the general's command, the troops advanced" has a similar connotation to the one with "behest".</u>
To confirm my assumptions, I looked the word up online and found it indeed means "order" or "command".
B. The Emperor of Blefescu
