Explanation:

The best revision of sentence 4 is the first one: "Just like homework and other activities, helping to take care of a dog teaches a child about responsibility".

Explanation: Sentence 4 includes contradictory information because it implies that doing homework does not help a child to develop a sense of responsability. In that way, as the author is intending to persuade readers to have dogs, the revision that is best written and aims at achieving this purpose is the first one: "Just like homework and other activities, helping to take care of a dog teaches a child about responsibility". This revision of sentence 4 recognizes that both taking care of a dog and doing homework help a child to become more responsible. In contrast, the other revisions go against the main purpose, include other contradictory information or fail to refer to the main topic.
