看英语解释 An edition is a particular version of a book, magazine, or newspaper that is printed at one time.
e.g.
A paperback edition is now available at bookshops.
平装本现在在书店可以买到。
A publication is a book or magazine that has been published.
e.g. They have started legal proceedings against two publications which spoke of an affair.
他们开始对两本提及一桩婚外情的出版物提起法律诉讼。
从英英字典的解释不难看出，publication指的是字典，而edition指的是版本。我们通常说字典里有什么内容，而不会说版本里有什么内容，这道题应该选D。
