The usual alpine response is caused by the lack of oxygen in the air at high altitudes. When the conditions of hypoxia change, the symptoms can quickly disappear. Acute cerebrovascular obstruction also has the symptoms of cerebral hypoxia, which can be life-threatening if not handled properly in time. Because the symptoms of acute cerebrovascular obstruction are similar to the general alpine response, the disease is particularly dangerous at high altitudes. Which of the following is most likely assumed by the above argument? ['The general alpine response and the medical treatment of acute cerebrovascular obstruction are different.', "Hypoxia at high altitudes may affect doctors' work and reduce their accuracy.", 'Acute cerebrovascular obstruction will not be life-threatening if timely and properly treated.', 'Lack of conditions for rescue and treatment of acute cerebrovascular obstruction in high altitude areas.']
