The frozen, well-preserved body of a man was recently discovered in a glacier as the glacier melted. Artifacts found on the body reveal that the man lived at least 4,000 years ago. The nature of the glacier indicates that the man died on virtually the same spot where his body was discovered. If the body had not been sealed in the glacier shortly after the man died, or if the body had thawed in the intervening millennia, it would not still be preserved.
Which one of the following is most strongly supported if all of the statements above are true?The body is preserved only because it was sealed in the glacier shortly after death and did not thaw afterward. Since the man lived at least 4,000 years ago and died where the body was found, the glacier must have been present there at least since shortly after his death.
So the glacier must be at least 4,000 years old, or very close to that.
(A) None of the artifacts found on the body were more than 4,000 years old.
Wrong. The artifacts show the man lived at least 4,000 years ago, but they could be older than that.
(B) The man whose body was discovered in the glacier did not freeze to death.
Wrong. The passage does not tell us the cause of death.
(C) The glacier that melted to reveal the ancient body is at least 4,000 years old.
Correct. The man lived at least 4,000 years ago, died where the body was found, and the body had to be sealed in the glacier shortly after death. So the glacier must have existed there for about
at least 4,000 years.
(D) The artifacts found on the frozen body would not have been preserved if they had not also been frozen.
Wrong. The passage says this about the body, not necessarily about the artifacts.
(E) The global climate is, on average, warmer now than it was 4,000 years ago.
Wrong. The melting of one glacier does not prove a global climate comparison.
Answer: (C)
