Answer:
What makes the sentence a compound sentence is that it has at least two independent clauses and no dependent clause.
Explanation:
Where two or more independent clauses are contained in a sentence, it is known as a compound sentence. It also includes the use of a comma, semicolon and coordinating conjunctions like "and", "for", but, "nor', "yet", "so".
other examples of a compound sentence are, "I called Mary but she didn't answer her phone", "I winked at her and she smiled back at me", 'the light went off so I turned on the lamp".
the first one you would have to add a conjunction to. That makes it correct.
For Example:
Arturo loves to hike and he's familiar with all the local trails.
The finishing point constructed by Twain is: when the old man is about to finish the story of Jim Smiley's jumping frog, another individual interrupts him. The narrator tries to leave the place, but the old man reaches it. The story ends with the old man who starts telling the narrator about a yellow cow with only one eye of Jim Smiley.
It is a story parallel to what is happening in the Usher house.
The palace in the description represents Roderick Usher, whose hair used to be blond, as the yellow banners that wave in the air; through his eyes (the windows of the palace), a harmonious mind could be perceived, and wise words used to flow from his mouth, described as a door of pearl and ruby. However, gloom befalls on Roderick; his hair turns gray, his eyes are reddened by tears, his thoughts are discordant, and his mouth utters only the wild laughter of a madman.
