### HideShow timer Statistics

Ordinary mountain sickness, a common condition among mountain climbers, and one from which most people can recover, is caused by the characteristic shortage of oxygen in the atmosphere at high altitudes. Cerebral edema, a rarer disruption of blood circulation in the brain that quickly becomes life-threatening if not correctly treated from its onset, can also be caused by a shortage of oxygen. Since the symptoms of cerebral edema resemble those of ordinary mountain sickness, cerebral edema is especially dangerous at high altitudes.
Which one of the following is an assumption on which the argument depends?

(A) The treatment for ordinary mountain sickness differs from the treatment for cerebral edema.
(B) Cerebral edema can cause those who suffer from it to slip into a coma within a few hours.
(C) Unlike cerebral edema, ordinary mountain sickness involves no disruption of blood circulation in the brain.
(D) Shortage of oxygen at extremely high altitude is likely to affect thinking processes and cause errors of judgment.
(E) Most people who suffer from ordinary mountain sickness recover without any special treatment.

The stimulus says that most people can recover from Mountain sickness (first/second line) - but does not mention anything as to whether any element of treatment is needed or not. It will be wrong to presume that that it can be without special treatment.

The only assumption can be the treatment for MS vis-a-vis CE, may be different - as in A.

Perfect explanation venksune - the key is not to assume that people suffering from MS can recover without any special treatment or no treatment whatsoever!

A is the OA (LSAT Reference)

C. Unlike cerebral edema, ordinary mountain sickness involves no disruption of blood circulation in the brain.

A is out of scope.
