Final answer:
The explanation of how milk is used in Animal Farm creates tension for the reader by exposing the unequal distribution of resources among the animals, particularly the pigs who claim the milk for themselves.
Step-by-step explanation:
In George Orwell's Animal Farm, the explanation of how milk is used serves to create tension for the reader by highlighting the unequal distribution of resources and power among the animals.
The pigs, who represent the leaders of the farm, take the milk for themselves, claiming it is necessary for their superior intelligence and leadership.
This creates tension as it demonstrates the pigs' hypocrisy in claiming to work for the benefit of all animals while they themselves enjoy special privileges.
