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)
Explanation
Find the sentence that needs nothing before it, then follow the words that point back.
- S opens: it introduces the event, a chunk of the Antarctic Plate colliding with the Eurasian Plate.
- P follows: “This fortuitous geological event” is that collision, which pushed the rocks up.
- R comes next: “this massive edifice” is the raised rock mass from P, now cooling.
- Q closes: “Thus” draws the conclusion that the Himalayas are an ongoing event.
A and B begin with “Thus”, which cannot open a passage, and D places R before P, before the edifice has been formed.
Answer: C
