Final answer:
Old Major could provide specific evidence for his counterclaim that man's argument is all lies by pointing out the injustices and mistreatment suffered by the animals at the hands of humans.
Step-by-step explanation:
In Animal Farm, Old Major could provide specific evidence for his counterclaim that man's argument is all lies by pointing out the injustices and mistreatment suffered by the animals at the hands of humans. He could cite examples such as how the farmer exploited the animals for their labor without giving them proper food, the cruelty inflicted upon them, and the unequal distribution of resources.
Old Major could also highlight how the humans manipulated and deceived the animals for their own benefit, using false promises and propaganda to maintain control over them. By presenting these examples, Old Major would demonstrate that the humans' argument is built on lies and hypocrisy, ultimately strengthening his claim.
