Question
A year is the amount of time it takes for a planet to orbit the Sun. If Earth is 1 astronomical unit (AU) away from the Sun, and Mercury is 0.40 astronomical units (AU) away from the Sun, how does the length of a year on Mercury compare to a year on Earth?
A year is the same amount of time for all planets.
A year on Earth is shorter than a year on Mercury because Earth is closer to the Sun.
A year on Earth is longer than a year on Mercury because Earth is larger than Mercury.
A year on Earth is longer than a year on Mercury because Earth is further from the Sun.

A year on Earth is shorter than a year on Mercury because Mercury is closer to the Sun.
The length of a planet's year is influenced by its distance from the Sun: the closer a planet is to the Sun, the faster it travels in its orbit, leading to a shorter year. Mercury, being 0.40 AU away from the Sun, orbits the Sun much quicker than Earth, which is 1 AU away. Therefore, a year on Mercury is significantly shorter than a year on Earth.
