In a ECB1101 (Consumer & producer behavior) scenario, which is the most defensible first step before any computation?
Why B
ECB1101 graders reward students who explicitly identify the framework before computing. Plugging numbers into a formula that doesn't apply is the #1 way to lose method marks. Computing everything wastes time. Reading options first leads to answer-fitting rather than answer-finding.
In ECB1101 data: On this pattern, ~52% of students pick A (formula-matching), ~28% pick B (the correct framework-first approach)

1Identify the structure
In a core market concepts question, first separate the variables you control from those you observe. ECB1101 typically frames this as a multi-part scenario; isolate the part the question is actually asking about.
2Apply the core framework
Use the core market concepts framework end-to-end — don't skip to the answer. The ECB1101 marking rubric awards method marks even when the final number is wrong, so showing the structure protects ~30% of the marks.
3Sanity-check + state the conclusion
Read your answer back to the original wording. Does it answer what was asked, in the units asked, with the precision asked? ECB1101 examiners regularly take marks for "right number, wrong units" or "right answer, not stated as a conclusion".
The trapThe most common error on this question pattern: confusing change in quantity demanded vs change in demand. In AskSia data this catches roughly 25-40% of students on first attempt. Slowing down on the structure-identification step (Step 1) is the single biggest defense.
