Read the information given below carefully and answer the following question.
Theorists are divided concerning the origin of the Moon. Some hypothesize that the Moon was formed in the same way as were the planets in the inner solar system (Mercury, Venus, Mars, and Earth)—from planet-forming materials in the presolar nebula. But, unlike the cores of the inner planets, the Moon’s core contains little or no iron, while the typical planet-forming materials were quite rich in iron. Other theorists propose that the Moon was ripped out of the Earth’s rocky mantle by the Earth’s collision with another large celestial body after much of the Earth’s iron fell to its core. One problem with the collision hypothesis is the question of how a satellite formed in this way could have settled into the nearly circular orbit that the Moon has today. Fortunately, the collision hypothesis is testable. If it is true, the mantle rocks of the Moon and the Earth should be the same geochemically.
Q. According to the passage, Mars and the Earth are similar in which of the following ways?
1. Their satellites were formed by collisions with other celestial bodies.
2. Their cores contain iron.
3. They were formed from the presolar nebula.

Similarities between Mars and Earth:

Core Composition:
- Both Mars and Earth have cores that contain iron.

Formation:
- Both Mars and Earth were formed from the presolar nebula, along with other inner planets like Mercury, Venus, and Earth.
Therefore, according to the passage, Mars and Earth are similar in terms of their core composition (contain iron) and formation (both were formed from the presolar nebula). This sets them apart from the Moon, which has a core with little or no iron and has a different proposed origin.
