Which of the following could result in the termination of a limited partnership?

• Mental illness of a partner
• Illegal purpose of the partnership
• All of the above
• Bankruptcy

This is a passage from my text:

Terminating a Partnership

Both general and limited partnerships may be terminated by agreement, judicial decree (e.g., bankruptcy), by death or incompetence of a partner, by destruction of the object of the partnership, or by impracticability of the project. In the event that a limited partnership is terminated, the limited partners receive back any capital contribution or profit in priority to the general partner.

So bankruptcy is definite, but what about the other two?
