To complete the sentence "The Earth ------------ around the Sun," we need to choose a verb that accurately describes the Earth's motion.
Step 1: Understand the context
The Earth’s movement around the Sun is a well-known astronomical phenomenon.
This is a circular or elliptical motion governed by gravitational forces.
Step 2: Analyze each option
- Option A (passes): This implies moving past something, not motion in an orbit. Hence, it is inappropriate.
- Option B (runs): This is more casual and used for people/animals; not suitable in a scientific context.
- Option C (revolves): This correctly describes orbital motion — the Earth "revolves" around the Sun once a year.
- Option D (stays): This implies no movement, which contradicts the actual fact.
Therefore, the only scientifically and grammatically correct word to fill the blank is "revolves."
