In 2006, after being declared missing for three weeks, a Japanese man was discovered asleep in the snow in a state similar to hibernation. In animals, hibernation is characterized by slower breathing, lower body temperature, and a slower metabolism. Although humans do not normally hibernate, the doctors who treated the man hypothesized that he had entered a state of hibernation.

Which of the following, if it could be carried out, would be most useful in an evaluation of the above hypothesis?


A. Verifying all details in the man's ID card

B. Checking the man's breathing, body temperature, and metabolism before he wakes up

C. Finding out whether the man is part of an experiment

D. Doing a practical test with another subject to assess the possibility of human hibernation

E. Researching the man's background to check the possibility that he was raised by animals

- If we can get these details, we can confirm that the body had went into the state of hibernation!
A. Verifying all details in the man's ID card
This doesn't help us understand if the body went into the state of hibernation!

B. Checking the man's breathing, body temperature, and metabolism before he wakes up
Yes, this is exactly what we were looking for. Since, these are the parameters that confirm if a body is in state of hibernation or not. Knowing this piece of information is critical!

C. Finding out whether the man is part of an experiment
Irrelevant!

D. Doing a practical test with another subject to assess the possibility of human hibernation
We are not concerned about any other body but the person's body in concern!

E. Researching the man's background to check the possibility that he was raised by animals
This will help us understand if humans hibernate or not but not if the body went into hibernation or not!
IMO B­

A. Verifying all details in the man's ID card Incorrect

not related with hibernation process

B. Checking the man's breathing, body temperature, and metabolism before he wakes up Correct

after checking these requirements , can say whether the man was in hibernation or not

C. Finding out whether the man is part of an experiment Irrelevant

that is not a fact

D. Doing a practical test with another subject to assess the possibility of human hibernation Incorrect

this choice talks about possibility of hibernation, but doctor already hypothesized the man was in hibernation state

E. Researching the man's background to check the possibility that he was raised by animals Irrelevant

Just being similar does not mean it is so.
According to definition of hibernation, temperature bla bla bla, the correct answer is B

The first sentence of the stem would make a good SC question; it sounds like they declared for three weeks that the person was missing, but they mean to say that they declared that the person had gone missing three weeks earlier.

There's no way to answer this question without knowing what the stem is saying, and I have no idea what they mean when they say the man was "discovered in a state similar to hibernation". The only thing we know about hibernation, from the stem, is that it is characterized by slower breathing, lower body temperature, and a slower metabolism. When the person was found in a "state similar to hibernation", what does that mean? I can only conclude that his breathing was slower than normal, his body temperature was lower than normal, and his metabolism was slower than normal. There's nothing else "the man was discovered... in a state similar to hibernation" could mean, from the information in the stem. And if that's true, answer B is useless to us, because we must already know about his temperature, breathing and metabolism if we know he was in a hibernation-like state. Answer B essentially just restates a premise, so it wouldn't give us new information that would help us establish the conclusion.

The only answer I find justifiable here is D. It's also unclear to me what the stem means when it says "humans don't normally hibernate". If by that they mean "it is unknown if humans are capable of hibernating" (or if they mean what is actually true in reality, that there is no evidence that humans can hibernate), then answer D becomes a good answer. We have two competing hypotheses upon discovering this person in the snow. Maybe he was genuinely hibernating for a few weeks, or maybe he was just asleep. If we learned by experimenting on other people that humans were incapable of hibernating, then that would make it very unlikely this person was, because hibernating is one of those things that a whole species either does or doesn't do. But if we learned by experimenting that people can indeed hibernate, then that would mean that the hypothesis that this person was at least has a chance of being true.

The writing in the stem isn't clear enough for any one answer to be clearly correct, in any case. I found the original source of the question online, and the source claims the answer is B, but the logic of the "official explanation" is wrong (it ignores one of the central premises of the stem), so I don't think the question makes sense.

Since the doctor hypothesized that the man is indeed hibernating, isn't he supposedly have checked for those symptoms of breathing, temperature, etc. ? I still don't understand 'B' as the answer.
