Explanation
Correct answer: D.
Choice D is the best answer. Text 1 states that the moon was formed from the debris “over the course of thousands of years,” while Text 2 states that the moon’s formation happened “immediately after impact, taking just a few hours.” This shows a clear difference in how the authors view the evidence for the speed of the moon’s formation.
Why the other choices are wrong
Choice A
Choice A is incorrect. While Text 2 suggests that the moon formed over “just a few hours” and Text 1 says it took “thousands of years,” neither one mentions when that formation occurred.
Choice B
Choice B is incorrect. While Theia isn’t mentioned in Text 2, neither text describes or disputes evidence of Theia’s existence.
Choice C
Choice C is incorrect. Neither text makes any claims about the similarity or difference between the moon’s surface and Earth’s surface.
