Please list the three types of rumours in Chapter 7 of "Animal Farm."

1. The rumours spread by the humans: They spread the rumour that the animals were dying of famine and disease and that "the animals were continually fighting among themselves and had  resorted to cannibalism and infanticide."

2. The rumours spread by Napoleon to counteract the rumours spread by the humans: During Mr. Whymper's weekly visits some of the animals, especially the sheep, were instructed by Napoleon to remark casually and spread the rumour that their rations had been increased. Mr. Whymper was deceived and he "continued to report to the outside world that there was no food shortage on Animal Farm."

3. The rumours concerning Snowball: It was rumoured that "he was hiding in one of the neighbouring farms, either Foxwood or Pinchfield" and that he was the cause for anything untoward that hapened on Animal Farm: "whenever anything went wrong it became usual to attribute it to Sowball."
