A living will is primarily designed to provide specific instructions regarding a person's healthcare preferences in situations where they are unable to communicate their wishes, particularly in cases involving terminal illness or condition. This is why the choice stating that a living will applies only in situations where the person is terminal is the correct answer.

In contrast to a living will, a durable power of attorney for healthcare grants authority to another individual to make medical decisions on behalf of the person. This can include a wider range of situations beyond just terminal conditions, making the scope of a durable power of attorney broader.

The other options do not accurately reflect the differences between the two documents. For instance, while a living will can be revoked, it is not inherently irrevocable. Additionally, a living will does not usually provide instructions specifically for ambulance personnel; rather, it is used for making end-of-life care preferences known to healthcare providers. Finally, although the living will may cover chronic conditions, it is typically most focused on acute situations like terminal illness rather than a comprehensive range of conditions.
