The students discussed a problem of the woman. Her problem is that she wants to drink coffee while they finalize a presentation.
They suggested two possible solutions.
One solution is that they meet at the library because it is quiet place, but the woman can’t drink coffee.
Another solution is that they meet at the student union because the woman can drink coffee, although it may too noisy with crowds for book fair and long lines in cafeteria
If I were the woman, I would definitely choose the first solution: meet at the library because it is a nice and quiet place where I will work my presentation precisely and immediately. Furthermore I don't like drink coffee while working.
