Question ID:PT16 S3 Q13 Passage:There are just two ways a moon could have been formed from the planet around which it travels: either part of the planet’s outer shell spun off into orbit around the planet or else a large object such as a comet or meteoroid, struck the planet so violently that it dislodged a mass of material from inside the planet. Earth’s moon consists primarily of materials different from those of the Earth’s outer shell. Stem:If the statements above are true, which one of the following, if also true, would most help to justify drawing the conclusion that Earth’s moon was not formed from a piece of the Earth? Correct Answer Choice:BChoice A:The moons of some planets in Earth’s solar system were not formed primarily from the planets’ outer shells. Choice B:Earth’s moon consists primarily of elements that differ from those inside the Earth. Choice C:Earth’s gravity cannot have trapped a meteoroid and pulled it into its orbit as the Moon. Choice D:The craters on the surface of Earth’s moon show that it has been struck by many thousands of large meteoroids. Choice E:Comets and large meteoroids normally move at very high speeds.
