Your task
Flag the sentences that are wrong about trade.
- Places trade because each one is better at making some things. Even when one island is good at everything, both can gain if each makes what it gives up least to make. Economists call this comparative advantage; here it is simplified.
- Invented stories to learn from. Prices and shops in them are made up, and this is not financial advice. Ask a trusted adult before buying or selling anything for real.
- Never share personal or payment details online. Nothing about you is collected.
Score
- Understanding trade — You understood how this part of trade works.
- Wise choices — You weighed your options before choosing.
- Fair play — You treated buyers and sellers fairly.
In real life
Comparative advantage is a real idea in economics, first written down about two hundred years ago. Real trade between countries also depends on rules, distance and politics, so it is never as simple as one page.
