问题 The passage is primarily concerned with discussing______ [br] If Bolte and his colleague are both correct, it can be inferred that the globular cluster Paloma 12 is approximately______

选项 A、5 billion years younger than any other cluster in the galaxy
B、the same age as most other clusters in the galaxy
C、7 billion years younger than another cluster in the galaxy
D、12 billion years younger than most other clusters in the galaxy
E、2 billion years younger than most other clusters in the galaxy

答案 C

解析 The best answer is C. Bolte claims that one cluster is 2 billion yeas older than most other clusters in the galaxy (lines 22-23). The colleagues claims Palomar 12 is 5 billion years younger than most other clusters (lines 24-26). If both clams are correct, Palomar 12 is 7 billion years younger than another cluster in the galaxy. The statement made in A is not implied by the two clams made by Bolte and his colleague, whereas the statements made in B, D, and E are false if the two clams are correct.
