Rearrange the parts of the Information Technology sentence in the correct order to form a coherent paragraph about the impact of IT.

Introduction / Context:
This rearrangement question presents four sentences about the impact of Information Technology on the modern world. We must order them so that they describe the importance of IT, the shrinking of distances, the concept of a global village, and the resulting equality of opportunity.

Given Data / Assumptions:

P: The Information Technology today is rightly called the Technology of the Century as it has found its application and use in every walk society of the world.
Q: Distances no longer exist and the world appears to have shrunk into a Global Village.
R: It is really a landmark achievement that more than six billion population of the world will soon be living in a virtual village, as compact as any small Indian village of a few thousand population.
S: The wisdom of the wisest is today available to the stupidest of the person thus ushering in an era of real equality of opportunity to all.
We must identify a smooth order among these.

Concept / Approach:
The paragraph should begin with a general statement about Information Technology and its importance. That role is clearly played by P. After establishing IT as the Technology of the Century, the paragraph should describe its effect on distances and communication, which is Q. Then, R elaborates the idea of a global village by giving a picture of the entire population living in a virtual village. Finally, S concludes with a positive outcome: equality of opportunity because knowledge is widely available. The order P Q R S matches option PQRS.

Step-by-Step Solution:
Step 1: Choose the sentence that can introduce the topic. P introduces Information Technology, calls it the Technology of the Century, and is clearly a topic sentence. Step 2: After P, a natural follow up is to show a major effect of IT. Q explains that distances no longer exist and the world has become a Global Village, which follows directly from P. Step 3: R then expands on the Global Village idea by visualising more than six billion people living in a virtual village, which is logically connected to Q. Step 4: S sums up the effects by explaining that wisdom is widely spread, leading to real equality of opportunity. This belongs at the end as a concluding thought. Step 5: Therefore, the coherent order is P Q R S, corresponding to option PQRS.

Verification / Alternative check:
Reading PQRS as a full paragraph gives a clear and smooth flow: first we define IT importance, then we see its effect on distance and the global village, then a specific vision of the world population in a virtual village, and finally the benefit of equal access to wisdom. Any other order either jumps directly into the global village idea without introducing IT, or concludes with an image rather than the broader moral of equality of opportunity. PQRS is the only sequence that reads like a well structured paragraph from introduction to conclusion.

Why Other Options Are Wrong:

QPSR: Starting with Q talks about distances and the world shrinking without any reference to Information Technology, so the cause of this change is missing until later.

RSQP: Beginning with R mentions a virtual village for six billion people without introducing IT or the concept of global village, which is confusing.

QRSP: Q at the start suffers from the same issue as QPSR, and the later order does not recover a smooth introduction.

QSPR: Similarly to other Q first options, this order lacks an explicit introduction of IT as the driving force, and the final sentences feel somewhat disordered.

Common Pitfalls:
Some students are attracted to dramatic sentences like Q or R and try to place them first. However, good paragraphs often begin with a clear topic sentence naming the subject. Whenever you see a sentence that names the central concept (here, Information Technology), it is usually the safest choice for the opening position.

Final Answer:
The correct arrangement of the parts is PQRS.
