Lesson 1 · Argument

🧩 Analysing & Evaluating Arguments

At advanced level you do more than spot an argument. You map how its parts connect and judge how strong the connections are.

🏗️ The anatomy of an argument

An argument has a conclusion (the main claim), premises (the reasons offered), often an unstated assumption linking them, and evidence. To analyse, map the chain: evidence → reason → conclusion. Then test each link.

Conclusion: cities should ban private cars. Reason: cars cause most air pollution. Evidence: pollution fell 20% during a car-free week. Assumption: the car-free week was typical.

Test each link: is the evidence relevant and sufficient, and does the assumption hold?

🔬 Evaluating strength

Ask: Is the evidence relevant, sufficient and representative? Is the reasoning logical or does it contain a fallacy? Does it consider counter-arguments? Is the conclusion proportionate to the evidence? Distinguish correlation (two things occur together) from causation (one causes the other).

Correlation ≠ causation: ice-cream sales and drownings both rise in summer, but neither causes the other.

Lesson 2 · Politics

🏛️ Global Governance & Human Rights

No world government exists. Global problems are tackled through treaties, organisations and the actions of states, each with their own interests.

🌐 International organisations

The United Nations was founded in 1945. Its Security Council has 15 members: five permanent members with a veto (the US, UK, France, Russia and China) and ten elected for two years. The General Assembly has all member states. Other bodies include the World Trade Organisation (1995), the World Bank, the IMF and the International Criminal Court.

Security Council: 15 members permanent (veto): 5 elected: 15 − 5 = 10

The ICC and WTO are separate bodies with their own treaties.

⚖️ Human rights and sovereignty

The Universal Declaration of Human Rights (1948) sets out rights to life, liberty, equality, education and fair trial. Tension arises between state sovereignty (a state governs itself without outside interference) and the responsibility to protect populations from atrocities. Critics say powerful states apply rules selectively, while supporters argue that international law gives weaker states a voice.

Lesson 3 · Economy

♻️ Sustainability, Energy & Trade

Economies need energy and trade to grow, yet both can damage the environment. Sustainability asks how to keep the benefits while limiting the harm.

⚡ The energy transition

The energy mix is the combination of sources a country uses: fossil fuels, nuclear and renewables (solar, wind, hydro). Switching away from fossil fuels reduces emissions but raises questions of cost, reliability (the sun does not always shine), jobs and energy security. A carbon tax charges emitters per tonne of CO₂.

renewable share = renewable ÷ total × 100 30 GW of 100 GW = 30% carbon tax $50 per tonne, 2000 tonnes emitted tax paid = 50 × 2000 = $100 000

Moving along the energy transition shifts share from coal and gas to renewables, so total emissions fall.

🔄 Trade, tariffs and the circular economy

Free trade lowers prices and widens choice but can hurt local industries. Tariffs (taxes on imports) protect jobs but raise prices. A circular economy reuses, repairs and recycles materials instead of the linear “take, make, dispose” model. Carbon-intensive imports raise the question of who is responsible for emissions: the producer or the consumer?

Balance three goals: environment, society and the economy; a good policy gives some benefit to each.
