Problem/solution.
Explanation:
A problem/solution text structure is when a passage is organized in such a way that the dilemma is provided or expressed, followed by what can be done to remedy that. In other words, it is a text structure where a problem is given, followed by a possible solution for that problem.

Thus, the text structure is a problem/solution structure.
