Again, depends on the subject, if the task is on a historic event, most likely all work will be very similar... If it's the demonstration of a theorem, they will all be exactly the same. I did math tests on university, it was requested to write theorems, what you think it was written besides copy paste of the book?
If it's to solve a mathematic problem, or a programming problem, I can copy the work of someone else and slight change the passages, professor can't notice since the solution is one unique with forced steps
So not a great example
I'm sure you understood what I meant. Math is not subjective to opinions. I can't say that I think 2 + 2 can be 5.
