1. In 2002, Bernard Wilson executed a deed by which he conveyed Greenacre for a consideration of one dollar, receipt of which was acknowledged, "to Bernie for life, then to Carey for life, but if Carey moves to another state, to Don for the life of Carey, then to the heirs of Carey if Carey does not move to another state and to the heirs of Don if Carey does move to another state." This deed was promptly recorded. During Bernie's lifetime, Carey's interest may best be described as a
   1. contingent remainder.
   2. shifting executory interest.
   3. vested remainder subject to complete divestiture.
   4. vested remainder subject to partial divestiture.
