In the following question the first and the last parts of an explanatory passage are numbered 1 and 6. The remaining parts P, Q, R and S are jumbled. The passage discusses the essay as a literary form and mentions Bacon. Read the passage and choose the option that gives the correct logical order of P, Q, R and S.

Introduction / Context:
This rearrangement passage talks about the fame of Bacon as a creative writer and explains the nature and origin of the term “essay”. The first sentence states that Bacon's fame rests mainly on his essays, and the last sentence tells us something about essay style. The middle sentences must introduce the idea of writing about essays, give the origin of the word, explain its meaning, and describe the range of the form.

Given Data / Assumptions:

• Sentence 1 states that Bacon's fame as a creative writer rests mainly on his essays.
• Part Q says that it may be desirable to write something on the essay.
• Part P notes that the term is derived from the French word “essai”.
• Part R explains that “essai” means experiment or attempt.
• Part S observes that the essay covers an enormous range of composition.
• Sentence 6 concludes that in style the essay is often self revelatory and illustrative.

Concept / Approach:
The logical structure starts with the importance of essays, then the suggestion to discuss them, followed by the origin of the word, its meaning, and finally a description of the scope of essays before moving to style. So we expect Q to follow the opening sentence, then P and R as an etymological pair, and S before the final stylistic comment.

Step-by-Step Solution:
Step 1: After sentence 1 introduces Bacon's essays, the author signals intent to discuss the form. Part Q does this by saying it may be desirable to write something on the essay, which clearly continues the thought. Step 2: Once the topic is introduced, the next natural step is to define the term. Part P states that the word is derived from “essai”. Step 3: Part R immediately elaborates by explaining that “essai” means experiment or attempt, which completes the etymological explanation. Step 4: With the origin and meaning established, part S comments that the essay covers an enormous range of composition. This prepares for sentence 6, which discusses essay style.

Verification / Alternative check:
Reading the sequence 1 Q P R S 6 shows a clear argument: Bacon's essays are important, so it is desirable to say something about essays, the term comes from “essai”, that means experiment, and the essay covers a large range, while in style it is often self revealing. Each sentence follows naturally, giving both origin and function of the essay form.

Why Other Options Are Wrong:
In PQRS, the derivation of the term appears before the decision to discuss the essay, which feels abrupt because there is no announced intention. In RPSQ, the meaning appears before telling us that the word is derived from “essai”, reversing the natural explanatory order. In SPRQ, the comment on range appears too early, before the basic meaning of the term is clarified.

Common Pitfalls:
A typical mistake is to focus only on vocabulary and ignore the rhetorical function of sentences. Sentences like Q that announce an intention usually appear near the start of a paragraph, not in the middle. Also, etymological pairs like P and R usually appear together in a fixed order: origin first, then meaning.

Final Answer:
The correct order of the parts is Q P R S, so the correct option is QPRS.
