Teacher:You are given a passage. You need to construct a question about the information present in the passage. Construct a question in such a way that (i) it is unambiguous, (ii) its answer is the whole paragraph. Avoid creating questions that can be answered correctly without actually understanding the paragraph.
Teacher: Now, understand the problem? Solve this instance: I don't think best friends always have to do and share everything together. This is a tall order that even couples don't always fulfill.

Best friends should appreciate each other's presence, but sometimes people just have different plans/tastes/preferences so that they can't or don't always want to do things together. Best friends should be able to care for each other even though they don't do everything together. The same goes for sharing things.
Student:
Do best friends always have to do and share everything together?
