Sentence arrangement: choose the most logical order of the labelled sentences P, Q, R and S to form a coherent paragraph about reading as an essential basic skill and why modern society is ignoring it.

Introduction / Context:
This para jumble question asks you to arrange sentences about the importance of reading and its role in language development. The task is to create a coherent paragraph that first defines reading, then explains its benefits, and finally comments on how modern life is neglecting this important activity. Understanding logical progression from definition to elaboration and then to social commentary is the key skill examined here.

Given Data / Assumptions:
R states that reading is an essential basic skills building activity.
S lists benefits such as vocabulary enrichment, idea collection, familiarity with writing formats and fluency in speaking, all of which depend on reading.
P says that one’s language fluency is determined by the quality of reading.
Q points out that although all cultures stress reading, in modern times this activity is being ignored.
We assume that all four sentences are meant to form one persuasive paragraph about reading habits.

Concept / Approach:
A well written paragraph usually starts with a broad definition or main claim, moves on to add supporting details, then narrows to a specific effect or application and finally comments on a contrasting modern trend. In sentence arrangement questions we therefore look for the general statement, supporting explanations, and concluding evaluation. We also check that pronouns and phrases like this activity have a clear reference in earlier sentences.

Step-by-Step Solution:
Step 1: Identify the general opening. R introduces reading as an essential basic skills building activity, which is a natural starting point. Step 2: After the definition we look for a sentence that adds broad benefits. S explains several outcomes of reading, such as vocabulary enrichment and speaking fluency, so it logically follows R. Step 3: P then focuses on one specific result, namely that language fluency depends on the quality of reading. This continues the idea of benefits at a more focused level and thus fits after S. Step 4: Finally Q contrasts the traditional stress on reading with the modern tendency to ignore it. The phrase this activity refers back to reading described in R, S and P, making Q an effective concluding remark. Step 5: Putting the sentences together in this order gives R S P Q, which corresponds to option RSPQ.

Verification / Alternative check:
Reading the sequence RSPQ as a single paragraph, the logic is smooth. First the writer states that reading is essential. Then the paragraph describes how reading enriches vocabulary, provides ideas and improves formats and speaking. Next it states that language fluency in particular is determined by the quality of reading, which narrows the focus to one key skill. Finally, the author laments that despite this importance, present day society is neglecting the habit of reading. No sentence feels out of place and each new idea builds on or comments on earlier ones, which confirms that RSPQ is coherent.

Why Other Options Are Wrong:
Option QRPS starts with Q, complaining that reading is ignored, before even stating why reading matters, which weakens coherence. Option PQRS begins with a rather narrow statement about language fluency and does not clearly introduce reading as an essential skill first. Option RPSQ jumps from the general statement in R to P, then to the complaint in Q, and only later lists benefits in S, which feels badly ordered. The extra option SRPQ starts abruptly with S, listing benefits without defining reading.

Common Pitfalls:
Students often misplace Q because they are attracted by the contrast in in all cultures and civilizations but in modern times. However, such contrastive comments usually work best after the core argument has been fully presented. Another pitfall is to start with P since it mentions language fluency, a familiar phrase, but this sentence is actually dependent on the broader concept of reading and therefore should not open the paragraph.

Final Answer:
The sentences form a coherent paragraph in the order RSPQ, so option RSPQ is correct.
