3. What does the flag of the farm look like? What does it represent? 4. How is the stolen milk justified? What does this explanation tell us about the animals as a whole?

For your first question, here is a quote from the text:

"Snowball had found in the harness-room an old green tablecloth of Mrs. Jones's and had painted on it a hoof and a horn in white. This was run up the flagstaff in the farmhouse garden every Sunday morning. The flag was green, Snowball explained, to represent the green fields of England, while the hoof and horn signified the future Republic of the Animals which would arise when the human race had been finally overthrown."

You need to submit your other questions one at a time.
