Rearrange the parts of the sentence in the correct order to form a meaningful statement: Some modern anthropologists hold that P: but also human behaviour Q: biological evolution has shaped R: not only human morphology.

Introduction / Context:
This question tests your ability to rearrange jumbled sentence parts into a coherent, grammatically correct and logically ordered statement. The topic is biological evolution and its influence on humans. Recognising standard patterns like “not only … but also …” is crucial to solving such rearrangement questions efficiently.

Given Data / Assumptions:

• Starter: “Some modern anthropologists hold that …”
• Fragment P: “but also human behaviour”
• Fragment Q: “biological evolution has shaped”
• Fragment R: “not only human morphology”
• We must place Q, R and P after the starter to form a meaningful sentence.
• We know that “not only … but also …” is a fixed correlative conjunction pair that must be kept together logically.

Concept / Approach:
A natural, grammatically correct sentence describing the idea here would be: “Some modern anthropologists hold that biological evolution has shaped not only human morphology but also human behaviour.” This structure begins with the verb phrase “biological evolution has shaped” and then uses the correlative pair “not only … but also …” to coordinate two objects: human morphology and human behaviour. Therefore, the correct order of fragments after the starter is Q R P.

Step-by-Step Solution:
Start with the given beginning: “Some modern anthropologists hold that …”Ask what they hold or claim: this should be followed by a clause beginning with the verb phrase “biological evolution has shaped”, which is fragment Q.Attach Q: “Some modern anthropologists hold that biological evolution has shaped …”Now we expect the pattern “not only … but also …” to introduce two parallel objects that evolution has shaped.Fragment R starts with “not only human morphology”, which must come immediately before “but also human behaviour”.Fragment P is “but also human behaviour”, completing the correlative pair.Thus the correct order is Q R P, corresponding to option QRP.

Verification / Alternative check:
Write the full reconstructed sentence: “Some modern anthropologists hold that biological evolution has shaped not only human morphology but also human behaviour.” This sentence is grammatically sound and expresses a clear scientific claim. If you try other combinations, for example RQP or PQR, the correlative pair “not only … but also …” gets broken or appears in the wrong order, producing either ungrammatical or awkward sentences such as “not only human morphology biological evolution has shaped but also human behaviour”, which is not acceptable.

Why Other Options Are Wrong:
Option RQP would produce: “… not only human morphology biological evolution has shaped but also human behaviour,” which disrupts normal English word order by splitting the verb from its subject phrase. Option PQR starts immediately with “but also human behaviour”, which cannot appear without “not only …” appearing earlier. Option PRQ similarly misplaces “but also” and leaves “not only” hanging. Only QRP respects both the basic clause order (subject + verb + object) and the correct positioning of “not only … but also …”.

Common Pitfalls:
Students sometimes over focus on the “not only … but also …” pair and begin with R or P immediately after the starter, forgetting that a full clause must have a verb. Always ensure that you first locate the main verb phrase of the clause, here “biological evolution has shaped”, and place it right after “hold that”. After the verb phrase, you can then insert the correlative pair and its two parallel objects. This method makes sentence rearrangement questions much easier and more systematic.

Final Answer:
The correct order of the parts is QRP, giving: “Some modern anthropologists hold that biological evolution has shaped not only human morphology but also human behaviour.”
