Sequence the following sentences in a coherent passage.
P: This fortuitous geological event generated a colossal amount of energy and heat that resulted in the rocks rising to an average height of 4 km across the contact zone.
Q: Thus, the geophysicists tend to think of the Himalayas as an active geological event rather than as a static geological feature.
R: The natural process of the cooling of this massive edifice absorbed large quantities of atmospheric carbon dioxide, altering the earth's atmosphere and making it better suited for life.
S: Many millennia ago, a breakaway chunk of bedrock from the Antarctic Plate collided with the massive Eurasian Plate.

Answer: C
The coherent order is SPRQ.
S opens the story with the event itself, the collision of a piece of the Antarctic Plate with the Eurasian Plate. P follows, because 'this fortuitous geological event' refers back to that collision and describes the uplift of the rocks. R continues with 'this massive edifice', the mountains just raised, and their effect on the atmosphere. Q, beginning 'Thus', draws the conclusion that the Himalayas are an active event, so it comes last.
Orders beginning with Q put the conclusion before anything it could follow from. SRPQ places R's 'this massive edifice' before P has described any rising rocks.
