Answer: The rebellion takes place when the animals got together and started a fight against the humans to finally get rid of them to start their own farm. The behaviour of the animals during the rebellion suggest human characteristics as they start doing human actions such us "Reading, Writing, Drinking, Sleeping in beds, trading animals products for their own benefits, etc.
Step-by-step explanation:
The Rebellion occurs because Mr. Jones starts drinking heavily after losing a lawsuit. Because of his drinking, he neglects the farm, sometimes spending days at a time doing nothing but sitting in a chair, reading the paper, drinking, and feeding Moses. As a result of his lack of supervision, his farm hands do little work, and the farm goes to wrack and ruin: the fields are weedy, the roofs are left unrepaired, and the animals are underfed.
Things come to a head when Mr. Jones celebrates Midsummer's Eve, gets drunk, doesn't come back until a day later, and then promptly falls asleep. His workers haven't been bothering to feed the animals. Finally, the animals get so hungry that they break into the store shed and start feeding themselves. When Mr. Jones and his men arrive and try to whip them out of the shed, the frustrated animals fight back and run the humans off the farm.
The animals had been secretly preparing for the rebellion they expected to someday take place, but they are surprised at how quickly and spontaneously it happens.
