This is Kawaijuku's "Mark-Shiki Kiso Mondai-Shu: Kobun, 6th Edition." It's a very easy-to-use book for getting used to the Common Test format questions. As you can see in the third photo, there is one place where a yellow highlighter has been used, but all other writing has been erased! If you have any questions or would like to negotiate the price, please feel free to comment! Thank you for looking.
