47. D。推断题。根据第1段最后一句Although he didn’t even know how to make coffee when he signed, he was quite confident.(He thought the experience would make a nice book.)可知虽然他甚至不会做起码的家务，但很自信，认为照顾家庭是很容易的并认为这是他写出一本好书所需要的体验。因此答案为D。
48. D。推断题。根据最后一段Now that Bob has publicly admitted he was wrong, he is routinely(日常地) sharing the child-raising and household tasks with Pat可知Bob已经公开承认错误并和Pat分担照顾孩子和做家务活。由此可推出他们签合同时达成的协议是：如果Bob不能遵循合同，就公开承认错误。故答案为D。
