Step 1: Understanding the Concept:
To reconstruct a jumbled sentence, we must identify the subject-verb core, align modifying phrases, and ensure logical transitions between clauses.
Step 2: Detailed Explanation:
Let us evaluate each part of the sentence:
- Q ("economists argue that") contains a reporting subject ("economists") and verb ("argue") followed by the conjunction "that."
This clause must be followed by a noun clause acting as the direct object. This makes Q the most logical opening part of the sentence.
- S ("free trade is a magic bullet - the quickest") introduces the subject of the subordinate clause ("free trade") and describes it.
The adjective "the quickest" is a superlative that must modify a noun. This implies S must connect to a noun starting the next part.
- P ("way to fuel growth") begins with the noun "way," which fits as the noun modified by "the quickest" in S ("the quickest way to fuel growth").
This creates a seamless connection from S to P (S-P).
- R ("and alleviate poverty") uses the coordinating conjunction "and" to connect the infinitive verb "alleviate" with the infinitive "fuel" in P ("to fuel growth and [to] alleviate poverty").
This completes the sentence logically, establishing the connection from P to R (P-R).
Combining these steps, the complete, grammatically correct sentence is:
"Economists argue that free trade is a magic bullet - the quickest way to fuel growth and alleviate poverty."
This sequence corresponds to Q - S - P - R.
Step 3: Final Answer:
The correct sequence is Q - S - P - R.
