The Answer is: (It) is a book about planets
A semicolon is used to separate two complete sentences that are related in some way. Answer choices A and D both use a semicolon to separate two complete sentences, however, answer choice A combined two unrelated sentences. D is correct.
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.
