QUESTION TYPE: Necessary Assumption
CONCLUSION: Cerebral edema is especially dangerous at high altitudes.
REASONING: Cerebral edema has symptoms that resemble those of ordinary mountain sickness. Cerebral edema can be fatal unless correctly treated from the start.
ANALYSIS: The argument is that it is hard to tell mountain sickness apart from cerebral edemas. So if cerebral enema occurs on a mountain we might misdiagnose it as mountain sickness. The patient could receive the wrong treatment and die.
The argument is assuming that the treatments are different. Otherwise a patient might receive the correct treatment even if people thought they had mountain sickness.
- CORRECT. If the treatments are the same then there is no problem if an edema is misdiagnosed as mountain sickness. The patient will get the right treatment anyway.
- Even if a patient doesn’t slip into a coma they might still die, if they aren’t treated correctly from the onset.
- This shows that mountain sickness is less dangerous than a cerebral edema. But it doesn’t change the fact that the outward symptoms of both diseases are similar.
- Even if this weren’t true it would still be easy to confuse the two diseases.
- Even if people with mountain sickness are always given treatment it could still be the wrong treatment for edema.
