Concept:Sentence jumble requires identifying the opening sentence and linking words to form a coherent sequence.
Explanation:Step 1: Sentence P stands alone as it introduces the subject—two people arguing about Venus's warmth.
Step 2: The adjective "warmer" in P naturally leads to the comparison with "than the Earth" in S, making S follow P.
Step 3: S mentions "Venus is closer" which directly links to the phrase "to the Sun" in Q, so Q comes after S.
Step 4: Finally, R provides the second argument about a thick atmosphere, concluding the sentence.
Thus the correct sequence is P, S, Q, R.
Answer:Option A: P S Q R
