Answer:
It takes away his sense of humanity and his ability to feel.
Explanation:
The memoir of Richard Wright titled "Black Boy" revolves around his childhood and growing up as an adult as a black boy. He details his upbringing in the Southern state of Mississippi and how he had to endure racism amidst the Jim Crow laws.
In the given excerpt, Wright talks about his father and the sharecropping he does. Now, sharecropping is when a landowner allows his tenant to plant in his land in return for a share of the produce. And in that case, Wright's father has been greatly affected by his work. Being a sharecropper seemed to have taken a toll on him, away from a sense of humanity and ability to feel anything.
Thus, the correct answer is the third option.
