Problem and Solution

Today I didn't go to the university because I had a fever and tired, so I didn't study for my new lesson.
Tomorrow I asked my friend about yesterday what did you learnt from Aj. Usa. In addition, Onnipha gave a sheet and taught me about the Problem and Solution, their were many discourse marker of Problems and Solutions.
Problem markers their were challenge, conflict, crisis and etc.
Solution markers their were to address, to cope with, to solve and etc.
Then I saw the exercises their were many exercises and they made me confused. However I observed the markers from the text, I got and understood but I can't wrote the main idea of the text because I confused it but I would tried it.
