• A. Q-S-R-P
• B. R-P-Q-S
• C. Q-P-R-S
• D. R-S-Q-P

Answer 1

Answer: (B)

R-P-Q-S

Here, R must follow S1 as R continues the line of thought introduced in S1- it tells how green plants provide us with fossil fuels (All the fossil fuel that we use today came from green plants. It took hundreds of millions of years for those plants to change into coal, oil and gas). P follows R as it tells us more about fossil fuels- how we are burning it all up, a statement made by Dr. Calvin. Q must follow P as it expands on P. S sums it up and links the rest of the sentences to S6. So the correct sequence is RPQS. The answer is option B.
