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

Introduction / Context:
This verbal ability question tests your understanding of how to arrange jumbled sentences to form a coherent paragraph. The four labelled sentences P, Q, R and S all talk about relationships, emotions and how changing inner interpretations can influence emotional quality both at work and in personal life. To arrive at the correct sequence, you must identify the introductory idea, the logical flow of cause and effect, and where generalising statements such as references to work and personal life naturally fit in the argument.

Given Data / Assumptions:

• Sentence Q says that relationships are easy until there is emotional turmoil.
• Sentence P states that this dynamic is the same whether at work or in personal life.
• Sentence R explains that changing the interpretation in the mind can change emotions and shift the emotional quality of relationships.
• Sentence S claims that changing the emotions in relationships opens entirely new possibilities in life.
• The task is to arrange these four sentences into the most logical paragraph.

Concept / Approach:
In sentence ordering questions, we look for the sentence that works best as an opening idea, usually one that introduces the main topic without referring back with pronouns like this or that. Next, we place supporting or explanatory ideas, and finally we position generalisations or concluding remarks. We must also ensure that pronouns and phrases such as this refer naturally to something that has already appeared in the sequence. The paragraph as a whole should show a clear progression from problem statement, through method of change, to broader consequences in life and relationships.

Step-by-Step Solution:
Step 1: Identify the best opening sentence. Sentence Q introduces relationships in general and the idea that they are easy until emotional turmoil appears. It does not depend on any previous reference, so it works well as the starting point. Step 2: After Q, sentence P naturally follows because it extends the idea by saying that this situation is the same whether at work or in personal life. The word this in P clearly refers to the situation described in Q. Step 3: Sentence R then explains how one can change relationships by changing interpretations in the mind, which leads to a shift in emotions and the emotional quality of relationships. This logically follows from the problem described in Q and P. Step 4: Finally, sentence S concludes the paragraph by describing the outcome: when emotions in relationships change, entirely new possibilities in life open up. This is a natural concluding statement after R. Step 5: Therefore, the best sequence is Q P R S, which corresponds to option QPRS.

Verification / Alternative check:
If you quickly read QPRS as one paragraph, it flows smoothly from the general nature of relationships, to their similarity across work and personal life, to an internal method of changing emotions, and finally to the positive consequences of such change. Other orders either create unclear references or break the natural cause and effect pattern. The sequence QPRS builds from basic description to specific psychological process and ends with a forward looking conclusion about life possibilities, which is the hallmark of a coherent paragraph.

Why Other Options Are Wrong:
Option QRPS places P after R, which makes the pronoun this in P refer ambiguously to changing interpretations instead of the earlier idea about relationships being easy until turmoil. Option PSRQ starts with P, but this uses the pronoun this before the idea in Q has been introduced, so the reference is unclear. Option RQPS begins with R, which immediately talks about changing interpretations in your mind without giving any context about relationships, making the opening abrupt and confusing. Therefore these sequences do not produce the most logical and coherent paragraph.

Common Pitfalls:
A common mistake is to focus only on local links between two sentences and ignore the need for a clear introduction. Another pitfall is failing to track pronoun references such as this, which must always have a clear and natural antecedent. Many test takers also get distracted by sentences that sound philosophical or impactful and place them at the end without checking whether they properly conclude the line of reasoning. To avoid such issues, always identify the topic sentence, follow the cause and effect pattern, and check that each pronoun clearly refers back to earlier content.

Final Answer:
The correct sequence of sentences is QPRS, so the correct answer is option QPRS.
