Rearrange the four labelled sentences P, Q, R and S to form a coherent paragraph about Type B malnutrition in developed countries. Then select the most logical order of the sentences from the options given below. P: The incidence and severity of Type B malnutrition will be shown to be worse if newer micronutrient groups such as the essential fatty acids, xanthophylls and flavonoids are included in the surveys. Q: Commonly ingested levels of these micronutrients seem to be far too low in many developed countries. R: Many national surveys reveal that malnutrition is common in developed countries. S: This is not the calorie and micronutrient deficiency associated with developing nations (Type A malnutrition), but multiple micronutrient depletion, usually combined with calorific balance or excess (Type B malnutrition).

Introduction / Context:
This para jumble tests your ability to arrange four sentences on the topic of malnutrition in developed countries, specifically Type B malnutrition. The sentences mention national surveys, a distinction between Type A and Type B malnutrition, the inclusion of newer micronutrient groups, and low intake of those micronutrients. The goal is to build a logically connected mini paragraph.

Given Data / Assumptions:

• R states that many national surveys reveal that malnutrition is common in developed countries.
• S clarifies that this is not the classical calorie or micronutrient deficiency seen in developing countries (Type A malnutrition), but multiple micronutrient depletion with calorie balance or excess (Type B malnutrition).
• P asserts that the incidence and severity of Type B malnutrition will appear worse if additional micronutrient groups like essential fatty acids, xanthophylls and flavonoids are included in surveys.
• Q notes that the commonly ingested levels of these micronutrients are far too low in many developed countries.
• We assume a good paragraph will introduce the problem, define it, then explain how evidence and specific nutrients make it look even more serious.

Concept / Approach:
The usual strategy for para jumbles is to find the opening sentence, track pronouns and referents, and identify cause effect or general specific relationships. R works as a natural opening because it introduces the surprising fact that malnutrition is common even in developed countries. S then explains what kind of malnutrition this is, explicitly contrasting Type A and Type B. P goes further by arguing that if we broaden the list of micronutrients considered, Type B malnutrition will look worse. Q then supports P by adding that the intake of these very micronutrients is already too low. This yields the order RSPQ.

Step-by-Step Solution:
Step 1: Choose an introductory sentence. R is the only one that introduces the general finding of malnutrition in developed countries, so it is the best opener.Step 2: Look for a sentence that explains what kind of malnutrition R is talking about. S begins with This is not and contrasts Type A with Type B, so it must directly follow R, producing RS.Step 3: After defining Type B malnutrition in S, the paragraph naturally moves to how its incidence and severity will be evaluated. P directly mentions Type B malnutrition and survey design, so RS is followed by P, giving RSP.Step 4: Q refers back to these micronutrients mentioned in P and supplies the reason why including them in surveys will highlight more serious deficiency: their intake is far too low. Hence Q must follow P, giving RSPQ.Step 5: Read the combined paragraph RSPQ to confirm that it flows smoothly: surveys identify malnutrition, it is defined as Type B, then the measurement is widened, and finally low intakes make the problem appear worse.

Verification / Alternative check:
Check the competing options. SPQR starts with S, which uses This without any clear antecedent. PRQS starts with P, which refers to Type B without first introducing malnutrition in developed countries, so it lacks context. RQSP puts Q immediately after R, but the demonstrative This in S then has no clear reference. Only RSPQ preserves all pronoun references and builds an argument step by step, which verifies it as the correct order.

Why Other Options Are Wrong:
SPQR and PRQS both violate the natural sequence of introducing a phenomenon, defining it, and then discussing measurement and supporting data. RQSP mixes the explanation and evidence in an order that makes the reference to these micronutrients confusing. In all three incorrect orders, the cohesion between sentences is weaker and key connectors like This and these do not clearly link back to earlier ideas.

Common Pitfalls:
A frequent mistake with para jumbles is to focus too much on topic words like malnutrition or micronutrients and ignore logical markers such as This is not or these micronutrients. These small words signal the direction of the argument and the sequence in which ideas should appear. Training yourself to spot pronoun referents and contrast markers is one of the most reliable ways to solve this type of question accurately.

Final Answer:
The most coherent order of the four sentences is RSPQ, so option C is correct.
