Rearrange the parts of the sentence in the correct order: Aggregate levels of undernutrition in India ______.

Introduction / Context:
This rearrangement question deals with a sentence about undernutrition in India. The segments describe how levels of undernutrition remain high despite improvements in stunting. The task is to place the three labelled parts in the correct order after the opening phrase Aggregate levels of under nutrition in India to form a meaningful and grammatically correct sentence.

Given Data / Assumptions:

• Opening phrase: Aggregate levels of under nutrition in India.
• Part P: remain shockingly high, despite the impressive.
• Part Q: stunting in the last decade.
• Part R: reduction in.
• Options: PRQ, QPR, RPQ, QRP.
• The sentence compares present levels of undernutrition with reductions in stunting.

Concept / Approach:
We first look for a verb to complete the sentence after the subject phrase. Part P contains the verb remain and an adverbial phrase, making it the natural immediate continuation. After that, the phrase despite the impressive introduces a concessive clause that requires a noun phrase to complete it, such as reduction in stunting in the last decade. This suggests that R and Q must follow P in that order, because reduction in needs stunting in the last decade to become complete.

Step-by-Step Solution:
Step 1: Attach P after the opening: Aggregate levels of under nutrition in India remain shockingly high, despite the impressive. Step 2: Observe that despite the impressive must be followed by a noun phrase, starting with reduction in. Step 3: Place R next: Aggregate levels of under nutrition in India remain shockingly high, despite the impressive reduction in. Step 4: Note that reduction in needs an object to specify what has reduced. Part Q, stunting in the last decade, fits perfectly here. Step 5: Add Q at the end: Aggregate levels of under nutrition in India remain shockingly high, despite the impressive reduction in stunting in the last decade. Step 6: Confirm that this order corresponds to P R Q.

Verification / Alternative check:
Reading the complete sentence confirms its clarity: Aggregate levels of under nutrition in India remain shockingly high, despite the impressive reduction in stunting in the last decade. The grammatical structure is sound, with the main clause followed by a concessive phrase introduced by despite. If we try other sequences such as QPR or RPQ, we find that they produce fragments like stunting in the last decade remain shockingly high or reduction in remain shockingly high, which are grammatically and logically incorrect. Hence, only PRQ yields a correct and meaningful sentence.

Why Other Options Are Wrong:
QPR would place stunting in the last decade immediately after the subject, making it difficult to connect logically to remain shockingly high. RPQ would yield reduction in remain shockingly high, which is ungrammatical because reduction in cannot function as a subject without its complement. QRP would start with stunting in the last decade, then reduction in, producing the fragment stunting in the last decade reduction in, which does not form a coherent phrase. None of these orders produces a smooth, correct sentence.

Common Pitfalls:
Learners may be tempted to focus only on meaning and ignore the small grammatical clues such as prepositions that require specific complements. For example, reduction in should immediately alert the reader that another phrase describing what is reduced must follow. Similarly, despite the impressive signals that a noun phrase is coming next. Ignoring such markers makes it easy to choose a wrong sequence. Paying close attention to such grammatical signals is a reliable strategy for solving rearrangement questions.

Final Answer:
The correct order of the parts is P R Q, so the answer is PRQ.
