Some parts of a sentence have been jumbled up, and labelled P, Q, R and S. Select the option that gives the correct sequence in which these parts can be rearranged to form a meaningful and grammatically correct sentence.
The dualism characteristic of medieval serfdom,
P may be traced all through
Q its formation out of debased
R freedom and rising servitude,
S the history of the middle ages.

Correct option is A

Option (a) QRPS is the correct order of the sentence parts.
Explanation of correct sentence order:
· The sentence begins with: “The dualism characteristic of medieval serfdom,” which introduces a contrast or complexity in the nature of medieval serfdom — the coexistence of opposing elements.
· Q – its formation out of debased: This logically follows because it explains how this dualism originated. The phrase “formation out of debased” introduces the starting point — something degraded or reduced from original freedom.
· R – freedom and rising servitude: This follows Q smoothly and completely explains what was "debased" — freedom, and what arose in its place — servitude. It continues the thought and provides the necessary historical context of contrast (freedom vs. servitude).
· P – may be traced all through: After presenting the basis of dualism (Q + R), this clause returns to the main point, saying that this duality can be seen throughout the period.
· S – the history of the middle ages: This completes the sentence logically by specifying where the dualism can be traced — through the history of the Middle Ages.
Final Rearranged Sentence:
“The dualism characteristic of medieval serfdom, its formation out of debased freedom and rising servitude, may be traced all through the history of the middle ages.”
How to Identify the Sequence:
· Start with conceptual origin or cause → “formation” Q).
· Then describe elements involved → freedom and servitude R).
· Move to observation or continuation → “may be traced...” P).
· End with timeframe/location – where this applies → “history of the middle ages” S).
This sentence builds from origin → contrast → spread → scope, which is a logical and grammatical structure in complex historical exposition.
