Input: Consider Input: The Secretary of the Treasury pays a taxable pension to the president. Former presidents receive a pension equal to the pay that the head of an executive department (Executive Level I) would be paid, as of 2017 $207,800 per year. The pension begins immediately after a president's departure from office. A former president's spouse may also be paid a lifetime annual pension of $20,000 if they relinquish any other statutory pension.

Output: pension of the president of the united states


Input: Consider Input: The hemisphere of the Earth experiencing daytime at any given instant changes continuously as the planet rotates on its own axis. The axis of the Earth's rotation is not perpendicular to the plane of its orbit around the Sun (which is parallel with the direction of sunlight), and so the length of the daytime period varies from one point on the planet to another. Additionally, since the axis of rotation is relatively fixed in comparison to the stars, it moves with respect to the Sun as the planet orbits the star. This creates seasonal variations in the length of the daytime period at most points on the planet's surface.

Output: why only half of the earth can receive sunlight at any given time
