Explanation:

1. Kinetic energy is energy of motion and potential energy is related to height (in a simple mechanical - energy context like a pendulum or an object in a gravitational field). At the lowest - point of an object's motion, it has maximum speed (and thus maximum KE) and minimum height (and thus minimum or zero PE).
2. When an object is falling (losing height), its potential energy decreases and its kinetic energy increases due to the conservation of mechanical energy.

Answer:

1. Without seeing the actual positions, assume the lowest - position among the given ones. If we assume a typical scenario like a pendulum or an object in free - fall, the answer would be the position with the lowest height. But since no diagram is provided, we can't give a definite number.
2. Similarly, the position where the object is descending (losing height) is the one where KE is increasing and PE is decreasing. Without the diagram, we can't give a definite number.
