Answer: A.
What this practice covers
Real past-paper questions, the answer key from the mark scheme, and the explanation that goes with it. Each one is marked the moment you pick, the correct option is shown whether or not you found it, and the full explanation opens either way. No account needed to answer them.
These questions are drawn from past AQA A-Level papers. You answer, you find out immediately whether you were right, and you get the reasoning for the correct option and for each distractor. Wrong answers go to a mistakes locker so you can come back to exactly those.
Practice is free. You need an account only so your progress and your mistakes are still there next time.
What examiners see students get wrong here
These are the errors that cost marks on economic methodology and the economic problem, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.
- Confusing positive (testable) and normative (opinion) statements. Check for "should" and "ought".
- Assuming a positive statement must be true. It only has to be testable.
- Treating a point inside the PPF as unattainable rather than inefficient.
- Saying resources are unlimited; it is wants that are unlimited.
- Defining opportunity cost as all forgone alternatives instead of the next best one.
- Forgetting ceteris paribus when explaining why a prediction did not come true.
Revise it first
If any of the above is unfamiliar, work through the notes before practising: Economic Methodology and the Economic Problem revision notes.
