"What is most affected by the sun's distance?" The given answer was "surface temperature", but Venus has a higher temperature than Mercury (confirmed in a later question,) even though Mercury is closer to the sun, so that has to be an incorrect answer. However, the orbits of each planet increase proportionately as their mean distance from the sun increases, so I would suggest that 'Orbit' should be the correct answer.
Mercury has virtually no atmosphere. Venus has a very dense atmosphere, holding the warmth of the sun close to the surface (runaway greenhouse effect). Venus is definitely correct, dude.
The atmosphere is what contributes to Venus's hot temperature. If the atmosphere of all the planets were the same, then it's easy to see that surface temperature is the answer.
I missed 2. I'm surprised they didn't put a pin-ball machine in there I used to play them for hours. The bed warmer I had no clue what that was & in fact still don't know how that contraption was used. Some of these were from way back but tape made its transformation from cassette to 8 track through VHS and finally to floppy disk (but first from 8" then to 5.25" and finally to 3.5" before finally going to CD/RW, CDR, and now to USB sticks & microSD).
To use a bed warmer you have to put some hot pieces of coal from the fireplace into the pan and put the lid on. You put the device between the sheets and let the dying ambers warm your bed. You have to be sure the lid stay over the pan or it would become a fire hazard.
But mostly the tilt of Earth’s axis. If the Earth was straight up & down, all parts of the planet would receive the same degree of sunlight 365.25 days a year.
