Sentence rearrangement (PQRS) — Build a historically framed sentence about Eskimos and Red Indians catching an aquatic animal: select the correct order of Q, P, R, S after the given opener 'Since the beginning of history'.

Given data

• Given opener: 'Since the beginning of history'
• Q: the Eskimos and Red Indians
• P: have managed to catch
• R: by a very difficulty method
• S: a few specimens of this aquatic animal

Concept/Approach
After the temporal opener, place the subject (Q), then the present perfect predicate (P), optionally insert an adverbial of manner (R), and end with the object (S).

Step-by-step reconstruction
1) Subject: Q → 'the Eskimos and Red Indians'.2) Verb phrase: P → 'have managed to catch' (matches long-standing action implied by 'Since...').3) Manner: R → 'by a very difficult(y) method' (acknowledging the minor spelling flaw as part of the source).4) Object: S → 'a few specimens of this aquatic animal'.Sequence: QPSR.

Verification/Alternative
Full sentence: 'Since the beginning of history the Eskimos and Red Indians have managed to catch by a very difficult method a few specimens of this aquatic animal.'

Common pitfalls
Placing S before P creates an object without a verb; starting with P omits a clear subject after the temporal clause.

Final Answer
Correct order: QPSR.
