Mains answer-writing practice — 28 September 2026

One original practice question a day from the official UPSC General Studies (Mains) syllabus. Written from scratch for this list — not a previous-year question and not copied from any coaching material, book or lecture. No model answer is given: write yours, then get it evaluated with the prompt linked below.

Evidence status: official documents read this run (28 September 2026). The syllabus topic, the paper pattern and the word limits below were read from the CSE 2026 notification and the CSM-2026 GS-III question paper on upsc.gov.in (links under Official sources). Open them to re-verify any fact before citing it.

Today's question (GS Paper III, 10 marks, 150 words)

Syllabus topic: General Studies-III — "Investment models" (CSE 2026 notification, Appendix I, Mains syllabus; also draws on "Infrastructure: Energy, Ports, Roads, Airports, Railways etc.").

Question: Private capital is often presented as the answer to India's infrastructure financing gap, yet several public-private partnership projects have stalled in renegotiation or dispute. Critically examine the investment models available for infrastructure creation in India. (150 words)

Format follows the official paper: GS papers carry 250 marks each with twenty compulsory questions — Questions 1–10 in 150 words, Questions 11–20 in 250 words (CSM-2026 GS Paper III, instructions page).

Directive word: critically examine

Critically examine asks for more than a description. It wants a judgment built in front of the examiner:

  1. Lay out the thing asked (here: the models — budgetary support, PPP variants such as BOT, HAM and TOT, asset monetisation/recycling, institutional finance).
  2. Test each against evidence — where it worked, where it stalled, and why (risk sharing, dispute resolution, financing cost, execution capacity).
  3. End with a balanced verdict: which model fits which situation, not a one-sided conclusion.

Contrast: discuss only debates the points; comment gives your view briefly; analyse breaks the topic into parts and shows how they connect. None of them demands the for-and-against verdict that critically examine does.

How to approach it (not a model answer)

  • Split the demand: (a) list the models with one identifying feature each; (b) examine each critically with one success and one failure/stress point; (c) close with a suitability verdict (2–3 lines).
  • Cover at least three dimensions: financing/fiscal, execution/risk, and institutional (contracts, regulation, dispute resolution).
  • Substantiate from official sources only: the Union Budget, the Economic Survey, NITI Aayog or RBI documents — never invent figures, committee names or project data.
  • Common pitfalls: writing only about PPPs and ignoring other models; giving features without criticism; ending without a verdict after a critically examine demand.
