Found: a notebook in the Friday lab
Black hardback notebook, left on the bench by the fume cupboard on Friday afternoon. I have not read it beyond the first page, which is a title and no name. The title is enough to tell me it belongs to somebody on this course and that it is most of a term's work, which is why I am posting rather than handing it to lost property, where it would sit in a box until June. If it is yours, tell me what is written on the inside of the back cover. I am not being difficult; three people have already claimed it and two of them clearly had not seen it. I am in the Wednesday lab from two and can bring it then, or I can leave it with the technician if that is easier. Tell me which.
25. What does the writer imply about the three earlier claims?
