Yoda creates a trust and makes all income payable to Obi for life. Yoda provides Zena with the power to appoint the remainder to whomever Zena desires during her life. If she fails to appoint, then the remainder goes to Hercules. Zena exercises her power by providing income to herself for life after Obi dies and providing Hercules with the remainder of the trust when she, Zena, dies. Zena dies. The value of the entire trust at her death is $$2,000,000.$ ?The value of Obi's interest is $$300,000.$

If Zena dies within $3$ ?years of the exercise of her power while Obi is still alive, Zena's gross estate inclusion is $$1,700,000.$

If Zena dies within $3$ ?years of exercising her power and Obi is dead, Zena's gross estate inclusion is $$2,000,000.$

If Zena dies within $3$ ?years of exercising this power, nothing is included in her gross estate regardless of when Obi dies.

Both the first and second choices are correct.

This is impossible to figure out.
