Interpreting Economics Questions (3C)

1.1.1 Scarcity & choice 1.1.2 How economic agents decide

Skill

Every economics question can be read through three C’s — command, context, content — and answered by building a causal chain from the context given to the content required. The technique is subject-general: it is illustrated here with Theme 1 examples but applies to any question, micro or macro, case study or essay.

When

Use it at the start of any question, before writing — especially short case-study parts and the framing of an essay. It is how you decide what a question is actually asking and which notes to draw on.

How

  1. Command — the directive word (explain, discuss, evaluate, …). It fixes the depth: a one-sided explanation, or two sides weighed to a reasoned judgement. This is the easiest C.

  2. Context — what is specific to this question: the scenario the examiner has chosen and can vary (a tax on sugar, an earthquake, a new stadium). Interpret it — what does it entail, which features matter?

  3. Content — the economics the question turns on, signalled by content keywords (cost, benefit, opportunity cost, price elasticity). This is the endpoint the answer must reach.

Then build the chain: start at the context (the cause), end at the content (the effect), and fill the interim causal steps that connect them. A complete answer is an unbroken cause-and-effect chain from the question’s scenario to the economic concept.

Example

“Explain one benefit and one cost the government may consider when deciding whether to build NS Square in central Singapore. [4]”

  • Command — explain: give reasoned points, no evaluation.

  • Context — building NS Square: what it entails — construction cost, a public amenity at the waterfront, alternative uses of the land and funds.

  • Content — cost and benefit from the government’s perspective, which by its goal means social welfare. The opportunity cost of the funds — schools, hospitals, transport — is a natural cost; greater community enjoyment of the facilities is a natural benefit.

The chain: NS Square in the city centre (context) → public amenity gained vs. alternative public spending forgone → net change in social welfare (content).
