The answer would be False, because theories change all the time.
I think the correct answer would be the last option. On a cloudless day, most of the visible light that is headed towards the Earth would reach the surface wherein some is being reflected and some is being absorbed. During this time, there are no hindrances for the light so it directly reaches the surface of the Earth and is absorbed or reflected by the objects it hits.
Thermal equilibrium is attained and the both rods are now at the same temperature.
<h3>What is thermal equilibrium?</h3>
Two bodies are said to have attained thermal equilibrium when the two bodies at the same temperature. It should be known that when two rods are firmly attached to each other heat flows from one rod to another.
As such, after some time, thermal equilibrium is attained and the both rods are now at the same temperature.

Answer:
<< how fast is it going when it was caught? >>
Working formula is
Vf^2 - Vo^2 = 2gH
where
Vf = velocity of stone when it was caught
Vo = initial velocity = 20 m/sec.
g = acceleration due to gravity = 9.8 m/sec^2 (constant)
H = height at which stone was caught = 5 meters (given)
Substituting values,
Vf^2 - 20^2 = 2(9.8)(-5)
Vf^2 = 400 - 98
Vf^2 = 302
Vf = 17.38 m/sec.
<< how long did the trip take? >>
Formula is
H = Vo(T) + (1/2)gT^2
-5 = -20T + (1/2)(9.8)T^2
4.9T^2 - 20T + 5 = 0
Using the quadratic formula,
T = 3.81 seconds
Hope this helps.
