(b)does not set below the horizon at the Antarctic Circle

(d)shines vertically overhead at the Tropic of Capricorn
Attempt This Question
Not attemptedCorrect Answer: (a) does not set below the horizon at the Arctic Circle
June 21 is the Northern-Hemisphere summer solstice, when the North Pole leans maximally toward the Sun. Consequently, every location on or north of the Arctic Circle (≈ 66.5° N) has 24-hour daylight, so the Sun never sets below the horizon there. By contrast, the Antarctic Circle is in 24-hour darkness, and the Sun’s vertical rays fall over the Tropic of Cancer, not the Equator or Tropic of Capricorn.
