Circle probably not right
Answer: A. Russell's sister takes after their mother, but he does not.
In the story, there is no implication of Russell not being obedient. He is so obedient he performs the job he hates everyday because his mother tells him to do so. There is also no sign of Russell's sister wanting to become a writer.
The author mentions that he has learned all of his mother's maxims as well, so that is not a difference between them. The difference is that his sister feels compelled to say them, and means them, because they align with what she thinks. This is because the sister is more similar to their mother than Russell.
I think the answer would be A.
The correct answer choice is answer B) Cell phones have lots of games on them that can entertain students during "downtimes."
Each other argument would be very helpful to both students and adults, so they would be relevant to the argument. Hope this helps!
