Dated Ages of Lunar Samples from Select Missions

The Apollo program missions were spaceflights to the moon led by the United States during the 1960s and 1970s during which astronauts collected some samples of the moon’s surface. More recently, China launched the Chang’e 5 mission, which returned additional lunar surface samples. Researchers have analyzed and dated each of the samples, concluding that the lunar samples collected during the Chang’e 5 mission are significant because blank

Which choice most effectively uses data from the table to complete the claim?

Back question 178 of 245 Next

Explanation

Choice A is the best answer because it effectively uses data from the table to complete the claim about the significance of the Chang’e 5 lunar samples. The table shows the approximate ages of lunar samples from four different missions: three Apollo missions and the Chang’e 5 mission. The Chang’e 5 samples are said to be approximately 2 billion years old, while the Apollo samples are each said to be more than 3 billion years old. In other words, based on the data in the table, the Chang’e 5 samples are much younger than those from the Apollo missions.

Choice B is incorrect because the table shows that the Chang’e 5 samples were taken from a landing site at Oceanus Procellarum, which none of the Apollo missions are shown to have visited. Choice C is incorrect because the table shows the Apollo 17 samples as approximately 3.8 billion years old, the Apollo 15 samples as approximately 3.3 billion years old, and the Chang’e 5 samples as approximately 2 billion years old, and therefore, the Chang’e samples are closer in age to the Apollo 15 samples than they are to the Apollo 17 samples. Choice D is incorrect because nothing in the text or table suggests that the Chang’e 5 samples were used to confirm the ages of the Apollo samples.
