In the sentence:
The students are taking a break from college exams in the restaurant.
My first thought was that the students have taken some exams, and they still have some more, so they are taking a short break.
But then some people argue that the students may also have finished all the exams, and are taking a break to relax themselves, just like a summer holiday is also referred to as a break. It's not necessary that they are to have more exams.
Then I wonder, is the second interpretation also possible? Could you help confirm it?
Taking a break from something always implies that you will be going back to it.
