To determine who has greater kinetic energy, we need to consider the formula for kinetic energy:

\[ KE = \frac{1}{2}mv^2 \]

where \( m \) is mass and \( v \) is velocity.

  1. If the wildlife keeper has a greater mass, their kinetic energy could be greater, especially if they are moving quickly.
  2. If the rabbit is smaller but running at a high speed, it may also have significant kinetic energy, depending on how fast it is moving compared to the keeper.

However, the question provides limited information, but typically, a larger mass at any speed generally implies greater kinetic energy, assuming the speeds are comparable.

Based on these considerations:

The most appropriate response would be: The wildlife keeper because they have a greater mass.
