The following question consists of four labelled sentences P, Q, R and S about the privatisation of Air India. When these sentences are arranged in the most logical sequence, they form a coherent paragraph. Select the option that gives the best order.

Introduction / Context:
This para jumble question deals with economic and policy discussion about foreign investment and privatisation of Air India. You are given four related sentences and must arrange them into a coherent paragraph. The task involves detecting which sentence introduces the topic, which sentences give developments and reactions, and which sentence provides a concluding view about closure after years of debate. Such questions measure your ability to identify logical flow and cause effect in editorial style passages.

Given Data / Assumptions:

• Q states that by clearing the path for 49 percent foreign investment in Air India, the Centre has decided to push ahead with privatisation.
• P says that this would bring a sense of closure to an issue that has involved about two decades of wrangling.
• R notes that the parliamentary standing committee on privatisation is yet to express its views, but political consensus seems close.
• S claims there cannot be a more opportune time to push ahead with disinvestment, despite improved operational performance of the airline.
• The sentences all revolve around the policy step, its timing, and the political context.

Concept / Approach:
We first look for a sentence that clearly introduces the main development. That sentence should not rely on a previous this or that for its meaning. Then we look for supporting or evaluative statements that refer back to this policy move, using words like this or it. Sentences about parliamentary committees and political consensus are generally placed after the basic policy announcement. Finally, we place broader evaluative or concluding remarks about timing and closure towards the end of the paragraph.

Step-by-Step Solution:
Step 1: Sentence Q is the clearest introduction, because it reports the main policy move: allowing 49 percent foreign investment in Air India and deciding to move ahead with privatisation. Step 2: Sentence P naturally follows Q. The pronoun this in P refers directly to the decision described in Q. It evaluates the policy move by saying it would bring closure to about two decades of wrangling over Air India. Step 3: Sentence R then comments on the political process. After the major decision is described and its significance is noted, R observes that the parliamentary committee is yet to express its views, but political consensus appears to be near. This fits as a follow up to the policy announcement and its longer history. Step 4: Sentence S is best placed at the end, because it offers a final evaluative remark on timing. It says there cannot be a more opportune time to push ahead with disinvestment, even though operations have improved, which is a closing judgement. Step 5: The resulting sequence is Q P R S, which corresponds to option QPRS.

Verification / Alternative check:
Reading QPRS as one paragraph yields a smooth editorial style: first the announcement of policy, then a comment on closure after long disputes, next an update on political consensus, and finally an evaluation of timing. There are no unclear pronoun references, and each sentence adds a new layer of information. The paragraph flows naturally from fact to history to politics to overall assessment, which is what newspaper opinion pieces tend to do when discussing policy changes.

Why Other Options Are Wrong:
Option SPQR starts with S, which refers to disinvestment and implies a context that has not yet been introduced, so it is a weak opening. Option PSQR opens with P, but this mentions this would bring closure without stating what this refers to, making the paragraph confusing. Option PRQS begins with P and then jumps to R, delaying the actual policy announcement in Q, which should logically come first because both P and R depend on it. Therefore these other sequences do not provide as clear and coherent a structure as QPRS.

Common Pitfalls:
Examinees often overlook the importance of pronouns like this and it, which must always refer back to a clearly stated earlier idea. They also sometimes start with sentences that sound dramatic instead of those that properly introduce the topic. To avoid these traps, always identify the sentence that describes the central event or decision first, and only then place evaluative and political context sentences around it, checking that each pronoun has an obvious antecedent.

Final Answer:
The most logical and coherent sequence is QPRS, so the correct answer is option QPRS.
