Is it important to know the basic arm and hand is message procedure?why? plsss I need your good answer.

The correct answer is A. He describes what Stanley’s mother often says.

Explanation:

The author chooses details so as to describe what Stanley's mother chooses to say, but also what she chooses to neglect. From the excerpt alone, we can't know what she really feels. She is certainly aware of the first Stanley's bad luck but she makes a conscious choice not to mention it. Instead, she is trying to focus on the bright side of things for the sake of her family, in an effort to change their bleak point of view.

We don't see how she often behaves, nor how the others tend to react to her.
