Which theme is shown mostly clearly in this excerpt

When I look at the answer choices, choice A would make sense for the first sentence, but not the rest. Choice B is supported by the part of the passage that says,  "...I am weightless again, flying past the other runners". The choice C isn't supported whatsoever because the passage does not say whether or not Squeaky wins, nor does it talk about working hard to prepare for the race. The choice D is supported by the positive self-talk and the resulting physical response (running faster) that the passage describes. This is why I believe D is the best answer.

D. Success is possible if one truly believes in oneself.

animal farm, written by george orwell, is a representation of russia after the revolution that led stalin to take over power.

in this excerpt, the central idea seems to be that the animals (a representation of society), when they believe to be working for a greater good and equality, are obedient and productive. they were convinced that, after expelling the owner (jones) from the farm, they would live in harmony and be fairly treated.

as we know, the pigs become the leaders and grow more selfish and dictatorial with time. in the end, they look and act in a way so similar to humans that it is impossible to tell the difference. the ideals of equality are shattered, and the farm turns out to be worse than it was before. the animals are manipulated with false propaganda and forced to work in order to enrich the pigs.
