Para-jumble (sentence arrangement): Arrange P–Q–R–S to complete the mystery paragraph about the Hound of the Baskervilles. S1 = "The Hound of Baskervilles was feared by the people of the area." P = "Some people spoke of seeing a huge, shadowy form — a hound — at midnight on the moor." Q = "But they spoke of it in tones of horror." R = "Nobody had actually seen the hound." S = "This shadowy form did not reveal any details about the animal." S6 = "The Hound of Baskervilles remains an unsolved mystery." Between S1 and S6, place P–Q–R–S in a cohesive order that preserves suspense and logic. Choose the correct sequence of P–Q–R–S that completes the paragraph.

Given data

• P: reports of a shadowy form at midnight.
• S: the form reveals no details—sightings are vague.
• R: in truth, nobody has actually seen the hound clearly.
• Q: despite this, people speak in tones of horror.

Concept/Approach
Place the report (P) before the pronoun reference in S ("This shadowy form"). Escalate from rumor → vagueness → lack of real sighting → fearful reaction.

Step-by-step reasoning
Start with P to introduce the shadowy reports. Follow with S to stress the indistinct nature of the sightings. Then use R to clarify that no one has truly seen the creature. Close with Q to underline the lingering fear.

Verification
This order sets up S6 (mystery remains) naturally: vague reports + no real sighting ⇒ unsolved.

Common pitfalls
Placing Q too early weakens the suspense arc and breaks the pronoun link in S.
