Read the following passage carefully before choosing the best answer.
Passage
The barometer at Station Seven did not merely record the pressure; it seemed to dictate the rhythm of Arthur’s breath. At eleven thousand feet, the air was a thin, jealous substance that had to be dragged into the lungs by force. Outside, the ice-storm did not fall so much as it paced, a restless, scratching beast circling the corrugated iron walls of the observatory. Inside, the dry heat of the oil stove kept the air at a parched eighty degrees, creating a climate of static electricity that made every touch spark. The world had shrunk to this metallic drum, vibrating in the teeth of the gale. Arthur found himself moving with a deliberate, agonizing slowness, not merely to conserve his meager oxygen, but out of a growing, irrational fear that any sudden gesture might crack the fragile seal between this artificial pocket of warmth and the devouring vacuum of the mountain night.

- By restricting the protagonist's physical actions while heightening his sense of vulnerability and psychological confinement.Answer
- DBy conveying the author's thematic warning regarding the dangers of scientific isolation in extreme climates.
- EBy verifying that the physical structure of the observatory is failing and will imminently collapse.
