Directive word: Describe

This question asks you to describe. The directive word signals the depth of analysis expected, the structure of your answer, and the weight of evidence you must bring.

See our UPSC directive words guide for a full breakdown of how to respond to each command word.

How this answer will be evaluated

Approach

The question demands descriptive-narrative responses across three distinct domains: rural sociology (PRA techniques), behavioural science (ethology), and applied nutrition (dairy feeding). Allocate approximately 20% time/words to part (a) (10 marks), 40% to part (b) (20 marks), and 40% to part (c) (20 marks). Structure with brief introductions for each sub-part, systematic elaboration of techniques/behaviours/nutrients, and integrated conclusions that link theory to field application.

Key points expected

  • Part (a): PRA techniques including Participatory Mapping, Transect Walks, Seasonal Calendars, Venn Diagrams, and Wealth Ranking with their specific applications in livestock-based rural planning
  • Part (b): Precise definition of ethology distinguishing it from animal psychology; comprehensive classification of behaviours including ingestive, eliminative, sexual, maternal, social, agonistic, and thermoregulatory behaviours with species-specific examples
  • Part (b): Detailed coverage of innate vs. learned behaviours, stereotypies, and their welfare implications in intensive production systems
  • Part (c): Identification of limiting nutrients in high-yielding cows: energy (negative energy balance), protein (rumen undegradable protein), minerals (Ca, P, Mg, trace elements), and vitamins (A, D, E)
  • Part (c): Strategic feeding approaches including phase feeding, TMR formulation, bypass nutrient technology, and transition cow management for metabolic disease prevention
  • Integration: Link between PRA-identified local feed resources and strategic feeding; ethological considerations in housing design for high-yielding herds

Evaluation rubric

DimensionWeightMax marksExcellentAveragePoor
Demand-directive understanding15%7.5Correctly interprets 'narrate' for (a) as systematic storytelling of PRA methods with field context; 'define' and 'describe' for (b) as precise conceptual framing followed by exhaustive behavioural taxonomy; 'discuss' for (c) as critical examination of nutrient limitations with strategic solutions, not mere listingPartial directive confusion—treats 'narrate' as simple listing, 'describe' as brief enumeration without depth, or 'discuss' as descriptive without critical evaluation of feeding strategiesFundamental misreading of directives—writes short notes for all parts, ignores 'define' requirement in (b), or fails to provide any evaluative element in (c)
Content depth & accuracy25%12.5Demonstrates command across all three domains: names specific PRA tools (Chambers' methodology), provides anatomical-physiological basis for behaviours (hypothalamus, limbic system), and cites precise nutritional requirements (NRC/ICAR standards for 40+ litre cows) with metabolic pathway awarenessAdequate coverage with some gaps—generic PRA description, behavioural classification without mechanism, or nutrient listing without strategic integration or specific requirement figuresSuperficial or erroneous content—outdated PRA methods, conflates ethology with general animal behaviour, or recommends inappropriate feeding strategies that would cause metabolic disorders
Structure & flow20%10Clear tripartite organization with visible sub-headings; logical progression within each part—PRA techniques from data collection to analysis; behaviours from definition to classification to welfare; nutrients from identification to limitation to strategic intervention; smooth transitions between theoretical and applied aspectsBasic structure present but uneven—parts identifiable but internal organization weak; some mixing of content between (b) and (c); abrupt shifts without linking sentencesDisorganized or merged response—no clear demarcation between sub-parts, random information dump, or failure to address all three parts distinctly
Examples / case-law / data25%12.5Rich contextualization: Indian PRA applications (NDDB's dairy cooperatives, BAIF's tribal livestock projects); specific behavioural examples (Flehmen response in cattle, allo-grooming in buffalo herds); quantitative data (NRC 2021 requirements: 0.75% Ca, 0.35% P for lactating cows; NEl requirements for 45L yield: 38-40 Mcal/day)Limited examples—mentions PRA without Indian context, behaviours without species specificity, or nutrients without numerical standards; generic references like 'high yielding cows need more energy'Virtually example-free or inappropriate—foreign case studies without relevance, incorrect data, or invented statistics; no connection to Indian dairy farming conditions
Conclusion & analytical edge15%7.5Synthesizes across parts: links PRA-derived farmer knowledge to customized feeding strategies; connects ethological stress indicators to metabolic disease prevention in high-yielders; offers critical insight on sustainability of intensive dairying or participatory vs. top-down extension approachesSeparate per-part conclusions without integration; standard summary statements; no critical evaluation of contradictions (e.g., high yield demands vs. welfare/behavioural needs)Missing or token conclusion; abrupt ending; or irrelevant philosophical statement unconnected to the three technical domains addressed
