'Venus' is to 'Earth' as 'Mercury' is to ____.
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Sun
The first pair links a planet with the body it comes nearest to. Venus is the planet that comes closest to the Earth, and Mercury is the planet closest to the Sun, so Mercury is to the Sun as Venus is to the Earth.
Why the other options are incorrect
Option (2) Pluto — Incorrect. Pluto is a dwarf planet far beyond Neptune, at the other end of the solar system from Mercury.
Option (3) Mars — Incorrect. Mars is the fourth planet, beyond the Earth; Mercury’s neighbouring planet is Venus, not Mars.
Option (4) Moon — Incorrect. The Moon is the Earth’s satellite; Mercury has no moon at all.
