In the following question on sentence arrangement, four labelled sentences P, Q, R and S are given. When arranged correctly, they form a coherent paragraph about the quality of kindness. Select the option that shows the most logical order of these sentences.

Introduction / Context:
This sentence arrangement question evaluates the ability to organise four jumbled statements into a connected paragraph. The sentences describe the quality of kindness and explain how it can be shown to different beings. To answer correctly, we must determine the introductory definition, the sequence of examples, and the natural flow of ideas.

Given Data / Assumptions:
The sentences are:
Q: Kindness is a quality that human beings show in various ways.
P: We can be kind to human beings who need our help.
S: We can be kind to our family members, relatives, friends and neighbours.
R: We can also be kind to other life forms like dogs, cats and other pets and domesticated animals, and to wildlife like birds and animals.
- The options provide different possible orders, and only one results in a clearly organised paragraph.

Concept / Approach:
A coherent paragraph about a moral quality like kindness usually starts with a broad definition, then provides examples of where and to whom kindness can be shown. Sentence Q explicitly defines kindness as a quality shown in various ways, so it is the natural introductory sentence. P and S both deal with kindness towards human beings, while R extends kindness to animals and other life forms. A logical progression would first define kindness, then mention kindness to people in general, then to specific groups like family and neighbours, and finally broaden the scope to include other creatures.

Step-by-Step Solution:
Step 1: Select the introduction. Q introduces the main idea by defining kindness as a quality shown in various ways. Hence Q should come first. Step 2: After the general definition, it is logical to show kindness toward other human beings who need help. P states "We can be kind to human beings who need our help", which naturally follows Q. Step 3: S narrows this further by identifying specific human relationships: family members, relatives, friends, and neighbours. This flows smoothly from the more general idea in P. Step 4: Finally, R broadens the scope again, reminding us that kindness is not limited to humans but extends to pets, domesticated animals, birds, and wildlife. This provides a suitable closing expansion of the idea. Step 5: Therefore, the order Q → P → S → R forms a coherent paragraph and corresponds to the option QPSR.

Verification / Alternative check:
Reading the sequence QPSR as a single paragraph yields a clear logical flow: the paragraph starts with a definition, then explains how we can help other people, then specifically our close social circle, and finally all living beings including animals and birds. The connections between sentences are smooth, and the message becomes increasingly inclusive. Other sequences either start with examples before giving a definition or mix human and animal examples in a way that feels less structured and less natural.

Why Other Options Are Wrong:
- QPRS moves directly from kindness in general to pets and animals, then back to family and neighbours, which creates a distracting jump in focus.
- PQSR starts with P, so the main quality of kindness is not clearly introduced before examples of helping human beings are mentioned.
- PQRS similarly begins with P instead of Q and leaves the general definition until later, which weakens the opening of the paragraph.

Common Pitfalls:
Students often look only for pronoun references like "We" without paying attention to how the examples are structured from general to specific. Another common error is to begin with a specific group (such as family) rather than with the wider definition. To avoid such mistakes, always search for the sentence that introduces the core idea and then place examples in an order that moves from the most general to the more detailed and specific.

Final Answer:
The most logical sequence of the sentences is QPSR.
