The following four labelled sentences P, Q, R and S, when properly sequenced, form a coherent paragraph describing forests. Select the most logical order of the sentences.

Introduction / Context:
This para-jumble question asks you to arrange four sentences about forests into a coherent paragraph. The sentences mention forests as beautiful landscapes, a treasure house of nature, places that people visit and the experiences they offer. Your goal is to find an order that moves smoothly from description to human interaction and then to a broader concluding idea.

Given Data / Assumptions:
- P: Forests make for beautiful natural landscapes and scenery.
- S: People enjoy going into the forests either on foot or on a safari.
- Q: They offer visitors and tourists the beauty of trees and plants of all kinds and a large variety of wildlife that inhabits the area.
- R: Forests are a treasure house of nature.
- We assume the paragraph should be logically connected and stylistically pleasant, starting from a general visual description, moving to people's visits, then describing what they experience, and finally giving a summarising statement.

Concept / Approach:
A natural way to build a paragraph about forests is to begin with their visual appeal, then mention how people interact with them, then explain what visitors see, and end with a broader, almost philosophical statement. P talks about forests as beautiful landscapes and scenery, which is a good introduction. S follows by mentioning people enjoying trips into forests. Q then elaborates on what tourists see during these visits. Finally, R, which calls forests a “treasure house of nature”, works as a concluding remark summarising their importance.

Step-by-Step Solution:
Step 1: Choose an opening that sets the scene. P, which highlights forests as beautiful natural landscapes, naturally introduces the topic.
Step 2: After describing the scenery, we can talk about people's interaction with it. S explains that people enjoy going into forests on foot or on safari.
Step 3: Q answers the implied question, “Why do they enjoy it?” by describing the beauty of trees, plants and wildlife that visitors encounter.
Step 4: R serves well as a concluding statement, calling forests a treasure house of nature and summarising their overall value.

Verification / Alternative check:
Read PSQR as a continuous paragraph. It begins with the scenic beauty of forests (P), then introduces people's enjoyment and visits (S), then details what is seen (Q), and ends with a general statement about forests as a treasure house of nature (R). The progression is smooth and each sentence naturally leads to the next. Other sequences, such as QPRS or QRPS, start with pronouns like “They” in Q without a clear antecedent introduced first, which is stylistically weak and confusing.

Why Other Options Are Wrong:
- QPRS and QPSR: Starting with Q makes “They” unclear because the noun “Forests” has not yet been introduced explicitly.
- QRPS and RPQS: These orders disrupt the flow by jumping between description, conclusion and visitor experience in a less organised manner, weakening coherence.

Common Pitfalls:
Students sometimes overlook pronoun references like “They” and “Them”. When a sentence begins with a pronoun, you should check whether the noun it refers to has already been introduced. If not, that sentence is unlikely to be the first one. Always use this pronoun-antecedent check as a quick test when solving para-jumbles.

Final Answer:
The most logical order of the sentences is PSQR.
