For each subtask:

    For each package:
        Write down some non-obvious thoughts about the challenges you might face for the task and give multiple approaches on how you handle them.
        For example, there might be some packages you must not use because they do not obay the rules:

        Discuss the pros and cons for all of these packages.
Create a list of package subsets that you could use to solve the task.
The list is sorted in a way that the most promising subset of packages is at the top.
The maximum length of the list is 5.
