As the question suggests, is it ethical for me to check if my supervisor is reading my whole report/paper? If yes, then can I add a line somewhere in the middle of the report to test whether or not he reads it? For example,
Please highlight this line if you read it.
I know that this may irritate him, but I want to verify that he's reading my work.
I tried to add a deliberate error, a very specific and big error just to check if he would catch it or not and the response I got was: "Seems fine just fix the typos and you are not good at explaining this specific thing..." The major errors were never found, which bothers me, as it proves he hasn't read the entire thing.
What would be a good approach to make sure he goes through all the report?
[UPDATE]
Thanks for all the comments, however most of the answers and comments are actually suggestions for me to write proper English, and does not answer the question originally asked that How should a student make his supervisor go through the whole documents?
Also my scientific writing possess all the quality writing, flow, punctuation and style that a good report should have. I have published in good journals, so i do not think that my report writing skill is bad.
