One major similarity between napoleon and snowball is _. a) they both want power over animal farm b)they both want animal farm to be run by animals, not humans c) they both are eloquent speakers d) they both are eager to build the windmill to provide the farm with electricity

The correct answer here is B.

Both Napoleon and Snowball definitely want the the farm run by animals by getting rid of Mr. Johns and they both are instrumental in spreading Animalism. But they are also different, Snowball wants animals to work together and run the farm, while Napoleon is more totalitarian and eventually usurps power.
