which best describes why a manor in the early middle ages was self - sufficient?\no housing was plentiful for all classes of people.\no a variety of crops provided the necessary food.\no baking and maintenance work were done on the premises.\no the manor castle had walls, which could protect the residents.
Answer
Brief Explanations:
Self - sufficiency in a manor meant it could meet its own basic needs. Food is a fundamental need, and a variety of crops providing necessary food is key to self - sufficiency. Housing abundance doesn't directly relate to overall self - sufficiency. Baking and maintenance are secondary aspects. Castle walls are for defense, not self - sufficiency in terms of resources.
Answer:
A variety of crops provided the necessary food.
