By Michiyoshi Nakahara, published by Obunsha "Kiso Eigo Chobun Mondai Seiko" (Basic English Long Passage Problem Mastery) I received this unused book a few years ago, but I have kept it without using it. There is some slight sun-fading, but there are no markings or folds, and it is still in good condition for use. Please feel free to ask any questions!
