Answer and Explanation:
1. The point of obligation of a person passes from the country to another individual when there is greater responsibility than that other individual requires. As shown in the question above, Desdemona had a strong obligation to care for and support her husband, as she lived in a time when women were "properties" of their husbands and were to devote themselves completely to them.
2. It is possible to have an obligation to parents and to another individual, as long as the person who has this obligation is able to organize well and get help, because having obligations to someone is a very big burden and the more people who have this obligation, the greater the burden.
3. The problems that can be generated from this is the overload of people who have obligations to many other people. In this case, to avoid these problems it is necessary to define priorities and delegate the obligations to those involved.
