In “The Pit and the Pendulum,” how does the narrator escape the pendulum?
topjm [15]
In "The Pit and the Pendulum," the narrator finds himself tied down flat, with a sharp pendulum slowly swinging downwards towards him.

He finds that he is unable to untie himself.

Earlier, he was given food, containing meat, and that food is within his reach, though he is tied down. 

He finds rats are in the cell with him, so he devises a plan.

He takes the meat from his dish and rubs it all over the ropes tying him down. The rats then jump up onto him and begin gnawing on the ropes. Eventually, he is able to split the chewed ropes and free himself.

Read the passage from Animal Farm.
Troyanec [42]

Answer:

Explanation:

These are the two that I would pick

<em>“If she herself had had any picture of the future, it had been of a society of animals set free from hunger and the whip."</em>

<em />

She didn't have any vision at all. She could not conceive of any kind of alternative. She did not have the brains. She only had the comparison of what it was like under Jones, which was so horrible.

Her tears however told her an entirely different story. She dreamed of cooperation, but what she got was something that made her cry. She is filled with anguish and torment knowing that Napoleon and the others were cruel dictators.

“This was not what they had aimed at when they had set themselves years ago to work for the overthrow of the human race.”

This is why she cries. <em>“This was not what they had aimed at when they had set themselves years ago to work for the overthrow of the human race.”</em>

<em> </em>

And while the major was speaking, she was protecting a bunch of ducklings. This shows that her maternal instincts were alive even when listening to the major talk about revolution. That was what she wanted: equality. What she got was THIS horrible result --  A result that had no end.
