Specialisation and free trade: five questions to try now
Real past-paper questions, the answer key from the mark scheme, and the explanation that goes with it. No account needed to answer them.
Question 1
What might encourage international specialisation between countries?
Answer: A.
The correct answer is A: free trade.
International specialisation means each country concentrating on what it produces at the lowest opportunity cost and obtaining the rest through trade. That only works if goods can actually move between countries, so free trade is what makes specialisation worthwhile: a country will not abandon domestic production of a good unless it is confident of being able to import it, and it will not expand an export industry unless it can reach foreign markets.
Why the other options are wrong:

Why the other options are wrong:
- D, tariffs, obstruct trade. Barriers push countries back towards producing more things for themselves, which reduces specialisation, indeed protecting domestic industry is the opposite of allowing specialisation to develop.
- B, inefficiencies in production, gives no basis for specialising. Specialisation rests on differences in opportunity cost between countries, not on inefficiency, and a generally inefficient producer has no comparative advantage to exploit.
- C, labour immobility, limits a country's ability to reallocate workers from one industry to another. Since specialising requires exactly that reallocation, immobility is an obstacle to specialisation rather than an encouragement.
Question 2
A country specialises in the production of steel, toys and textiles. What is a disadvantage of specialisation for the country’s workers?
Answer: B.
The correct answer is B: they could become structurally unemployed if global demand changes.
Specialisation narrows what workers do, and narrow skills are risky. If world demand for steel, toys or textiles falls, because tastes change, or a cheaper producer emerges elsewhere, the industry contracts and its workers find their skills do not transfer to whatever is expanding. That mismatch between the skills workers have and the jobs available is structural unemployment, and it can persist for years. The concentration is often geographical too, so whole regions are affected at once.

Why the other options are wrong:
- A says they cannot afford products from other countries. Specialisation raises productivity and therefore incomes, and trade brings in foreign goods more cheaply than domestic production could.
- C says they have to learn a variety of skills. Specialisation means the opposite, each worker concentrates on a narrow range of tasks, which is precisely why the risk in B arises.
- D says too much choice wastes their time. This is not an economic disadvantage of specialisation in any recognised sense.
Question 3
Malaysia and Indonesia specialise in the production of palm oil. What is a disadvantage of specialisation?
Answer: C.
The correct answer is C: reliance on trade with other countries for other goods.
Specialising in palm oil means Malaysia and Indonesia do not produce the full range of goods they need, so they must import food, machinery, fuel and manufactures. That dependence is the disadvantage: it exposes them to export bans, shipping disruption, war and sudden price rises abroad, and to the volatility of the single commodity their earnings rest on. A country that cannot feed or fuel itself has surrendered a degree of control over its own economy.

Why the other options are wrong:
- A, concentrating labour where it is most productive, is the central benefit of specialisation. Higher productivity is why countries specialise at all.
- B, creating jobs to meet world demand, is a benefit, employment and export earnings.
- D, rising palm oil prices, is a benefit to producers, since it raises their export revenue. (Volatility of that price is a genuine risk, but a rise is good news for the exporter.)
Question 4
Protectionist policies reduce the level of global economic growth. What is a possible reason for this?
Answer: A.
The correct answer is A: incomes earned from trading decline.
Protectionism reduces the volume of international trade. Less trade means less specialisation according to comparative advantage, so countries produce more things they are relatively bad at making and fewer of the things they do best. Total world output falls, exporters lose sales and the incomes generated by trading, wages, profits, shipping and distribution earnings, decline. Lower incomes then mean lower spending, so global growth slows.

Why the other options are wrong:
- B says tariffs encourage trade. Tariffs are taxes on imports, so they discourage trade by raising its price. This would explain growth rising, not falling.
- C says average production costs decrease. Protection does the opposite: producing domestically what could be imported more cheaply raises costs, and sheltered firms lose the scale economies that come with serving a wider market.
- D says the production possibility of an economy expands. Protection restricts access to cheaper inputs and to foreign technology, so if anything productive capacity grows more slowly.
Question 5
The US imposed tariffs on cars and motorcycles from Germany. What is the effect of these tariffs?
Answer: B.
The correct answer is B: a decrease in trade between the US and Germany.
A tariff on German cars and motorcycles raises their price in the US, so American buyers purchase fewer of them and German exports to the US fall. Germany is also likely to retaliate with barriers of its own, reducing US exports to Germany. Trade between the two contracts on both sides, the direct and certain effect of the measure.

Germany is also likely to retaliate with barriers of its own, reducing US exports to Germany. Trade between the two contracts on both sides, the direct and certain effect of the measure.
Why the other options are wrong:
- A, a decrease in US inflation, is the wrong direction. Tariffs raise the prices Americans pay for imported vehicles, and domestic producers facing less competition can raise theirs too.
- C, an increase in profits of German producers, is reversed. German firms either absorb the tariff by cutting their prices, which squeezes margins, or pass it on and lose sales. Either way profits fall.
- D, an increase in living standards in both countries, is also reversed. American consumers face higher prices and less choice, German exporters lose sales and jobs, and both countries forgo some of the gains from specialisation. Total welfare falls.
What this practice covers
These questions are drawn from past Cambridge IGCSE 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 specialisation and free trade, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.
- Describing specialisation by workers when the question asks about countries.
- Listing advantages without a mechanism. Say why specialisation lowers prices.
- Forgetting over-dependence, the strongest disadvantage.
- Ignoring that specialisation only works if there is trade; a specialised country must be able to import.
- Missing the difference between the effects on consumers, firms and the economy, when the question names one of them.
