The correct answer to this open question is the following.
Churchill’s quote that accurately describes the relationship between Hitler and Chamberlain is the following: "You were given the choice between war and dishonor. You chose dishonor and you will have war."
Neville Chamberlain had been the British Prime Minister at the beginning of the war. Winston Churchill seriously opposed Chamberlain's policy of appeasement that grated Nazi leader, Adolph Hitler, many concessions to avoid another war. Chamberlain had accepted to grant Hitler some territories to appease Hitler's ambition and Winston Churchill found this intolerable and in the end, he was right. Hitler's troops invaded Poland on September 1m 1939, and this represented the beginning of World War II.

Answer:
Two stars (a and b) can have the same luminosity, but different surface area and temperature if the following condition is met:
(T_a^4)(R_a^2) = (T_b^4)(R_b^2)
Explanation:
The luminosity of a star is the total energy that produces in one second. It depends on the size of the star and its surface temperature.
L = σ(T^4)(4πR^2)
L is the luminosity f the star, T is the temperature of the surface of the star and R is its radius.
Two stars can have the same luminosity if the relation between the radius and the surface temperature is maintained.
To see this lets suposed you have 2 stars, a and b, and the luminosities of each one of them:
L_a = σ(T_a^4)(4πR_a^2)
L_b = σ(T_b^4)(4πR_b^2)
you can assume that L_a and L_b are equal:
σ(T_a^4)(4πR_a^2) = σ(T_b^4)(4πR_b^2)
Now, you can cancel the constants:
(T_a^4)(R_a^2) = (T_b^4)(R_b^2)
as long as this relation between a and b is true, then the luminosity can be the same.

Explanation:
Effects of Wind
on forecasted temperatures
At night, the earth's surface cools by radiating heat off to space. The strongest cooling takes place right near the surface while temperatures at roughly 3000 feet are actually warmer than those at the surface. On a windy night, some of the warmer air aloft is mixed down towards the surface. This occurs because the winds are faster aloft than at the surface.
To visualize this, place one hand over the other about six inches apart. The bottom hand represents the air near the surface and the top hand represents the warmer wind higher up. Move the bottom hand slowly and the upper hand faster (to indicate the faster winds aloft). The faster air above and slower air below causes the air to overturn or spin (as in the picture below). This overturning motion is how warmer air from above is transported downward on windy nights.
