Answer: Problem/solution/solution/recommendation
Explanation:
This outline uses the problem/solution/solution/recommendation approach.
This pattern separates data into three main sections: the description of the problem, possible solutions, and a recommended solution out of the options provided.
In this example, the problem is explained first, in a Problem Statement about choosing permanent catwalks or temporary scaffolding.
Then, there´s a set of possible solutions for that problem.
And finally, one of the solutions is chosen as the best option available.
