[A] Earth
[B] Venus
[C] Jupiter
[D] Saturn
Show Answer
Correct Answer: B [Venus]
Notes:
Through a small telescope, it is possible to see Venus undergo phases, just like the Moon. This occurs because, from our point of view on Earth, we see only the parts of Venus that are illuminated by sunlight at any given time. However, unlike the Moon, though, Venus is usually brighter to our view in its crescent phase than in its full phase.

[D] the axis of the earth is inclined more towards the sun in winter
Show Answer
Correct Answer: A [the earth is closer to the sun in summer than in winter]
Notes:
Summer is warmer than winter (in each hemisphere) because the Sun’s rays hit the Earth at a more direct angle during summer than during winter and also because the days are much longer than the nights during the summer. These effects are due to the tilt of the Earth’s axis. Also the earth is closer to the sun in summer than in winter.
