Concept:Jumbled sentence rearrangement tests logical sequence and grammatical coherence. The correct order forms a meaningful, grammatically correct sentence.
Explanation:Start with part S: "it is widely believed that the parliamentary system differs". This introduces the main clause.
Next, part Q: "from a non-parliamentary system". This completes the comparison by stating what it differs from.
Then, part R: "in as much as the former is". This explains the reason for the difference.
Finally, part P: "more representative than the latter". This finishes the comparison with the contrasting quality.
The full sentence is: "It is widely believed that the parliamentary system differs from a non-parliamentary system in as much as the former is more representative than the latter."
Thus the correct order is S, Q, R, P.
Answer:Option A (SQRP) is correct.
