Answer (A): The argument states that you can't apologize sincerely without intending not to repeat the wrongful act, but it never states that you cannot do the wrongful act again. The intent to do the act and actually doing it are two different things. This answer choice mixes up the intent and act, as one can sincerely intend never to do something again and then later end up doing it by mistake.
Answer (E): The argument states in sentence 2 that a sincere apology means you acknowledge that you acted wrongfully. In sentence four, it says that to sincerely accept an apology is to acknowledge a wrong. This answer choice simply connects these two ideas into one sentence, meaning it is fully supported by the premises provided.
