Answer:
it's the last one because I looked it up
Answer: It repeats the word "ask" in sentences with similar structures.
Explanation: The second and fourth options are completely unrelated with the concept of parallelism. The first and third options, on the other hand, are both related to parallelism, but the third option must be discarded because the contrast between "ask" and "ask not" is not repeated in each of the paragraphs; only the verb <em>ask</em> in its imperative form is repeated in each sentence.
Truth be told, it could be two. A would make sense in that the way the sentence is worded, the turtle herself seems weak. while C is also true to the word dragging as that would make it's movements awkward and difficult. I'd say your best bet would be C as turtles heavy backs and it's slowly speed would make the term "Dragging" make more sense.
At the beginning of the novel Animal Farm, the animals wanted freedom. They no longer wanted to be slaves to mankind.
By the end of the novel, the animals are no longer slaves to mankind -- now, they are slaves to the pigs. The animals have substituted one master for another and will not get the freedom they once desired.
The pigs went from wanted freedom for all to just wanting freedom for themselves. They are no better than men.
In this way, they have gone against the ideals they professed to hold at the beginning of the novel.
