AQA GCSE Geography Paper 2, June 2025: Question 3

📐 Step-by-Step Calculation

1. Step 1: Rank the data
   Write the 9 values in order from lowest to highest (ascending order).
2. Step 2: Locate the middle position
   Formula: (n + 1) / 2 = (9 + 1) / 2 = 5th value.
3. Step 3: Identify the 5th number
   From the provided dataset, the 5th value is exactly 3.51 .
4. Step 4: Check precision
   The question asks for two decimal places: 3.51 is already given to 2 d.p.

✅ Correct Answer & Marks

Median well-being score = 3.51

❌ Common Errors

• Calculating the mean (adding all values up and dividing by 9) instead of the median.
• Picking the middle number from the raw map/list without arranging them in numerical order first.
• Rounding incorrectly or truncating to one decimal place (e.g. writing 3.5 instead of 3.51).

✅ Acceptable Answers (Any 1)

• High standard of living / high GDP per capita (High-Income Countries - HICs).
• Access to high-quality healthcare and universal education.
• Stable democracies / good governance / political freedom.
• Absence of conflict, civil unrest, or war.
• Temperate climates with reliable rainfall and very few extreme natural hazards.

🧠 Exam Technique

This is a 1-mark "suggest" question testing AO3. You do not need an essay: a concise, single-sentence factual explanation earns the full mark instantly.

Example answer: "Countries with higher scores tend to be High-Income Countries (HICs) with well-funded healthcare and education systems."

💡 Key Knowledge

Organic food is grown without artificial fertilisers, synthetic pesticides, or routine antibiotics. UK demand has shifted due to:

• Health & environmental concerns: Rising interest in natural, sustainable diets has expanded demand.
• Cost of living pressures: Because organic produce carries a price premium, inflation and tightened household budgets can also depress demand.

Both positive or negative angles are fully credited!

✅ Model Answers (1 + 1 mark)

Positive trend route:
"Demand for organic food has grown as consumers become more concerned about health and chemical pesticides [1 mark], leading more UK farmers to convert their land to certified organic production to supply supermarkets [1 mark]."

Cost-of-living route:
"Higher food prices mean fewer consumers can afford premium organic products [1 mark], which has led some UK farmers to scale back organic farming due to falling sales [1 mark]."

❌ Common Errors & Examiner Warnings

• Single-point answers: Simply writing "Demand has gone up" scores only 1 mark. You must develop the consequence on farming (e.g. "...so more land is farmed organically").
• Off-topic discussion: Discussing food miles, agribusiness, or carbon footprints without directly linking to organic farming.

🧠 Level Descriptors & Mark Scheme Rules

• Level 3 (5–6 marks): Detailed, balanced understanding of challenges (AO2) + thorough evaluation using both Figure 12 and own knowledge (AO3). Clear concluding judgement.
• Level 2 (3–4 marks): Clear explanation of challenges + some direct application of Figure 12 and own understanding.
• Level 1 (1–2 marks): Basic statements, largely copying words from Figure 12 without elaboration.
• CRITICAL RULE: "Max top Level 2 (4 marks) if Figure 12 OR own understanding only." You must integrate both to reach Level 3!

💡 Evidence Checklist

From Figure 12:

• "No river in England is clean" according to MPs.
• Pollution sources: water company sewage spills, agriculture (farm run-off/slurry).
• Pollutants: microplastics, car tyre particles, motor oils, wet wipes.
• Risks to human health (e.g. wild swimmers, anglers).

From Own Knowledge:

• Eutrophication: Nitrate/phosphate fertiliser run-off triggers algal blooms, depleting oxygen and suffocating fish.
• Infrastructure strain: Victorian combined sewage systems overflow during heavy rain storms.
• Counter-balance / Successes: UK drinking water standards are among the safest globally; strict Environment Agency fines and improved wastewater treatment works.

✅ Model Answer (Level 3 - 6 Marks)

I largely agree that managing water pollution in the UK is a significant and worsening challenge.

As highlighted in Figure 12, agricultural run-off and water companies releasing untreated sewage have contaminated every English river. Intensive farming causes nitrogen-rich fertiliser to wash into rivers, causing eutrophication, which starves aquatic ecosystems of dissolved oxygen. Furthermore, Figure 12 reveals modern pollutants like microplastics, wet wipes, and vehicle tyre particulates washed from road networks. These diffuse sources are virtually impossible to filter out before entering waterways, posing direct health hazards to recreational users like wild swimmers.

However, the UK is not completely powerless. The Environment Agency imposes strict legal standards and has begun issuing record multi-million pound fines to water utility firms to force investment into modernising Victorian storm overflows. Tap water across the UK remains strictly treated, highly monitored, and safe to drink.

In conclusion, while the UK possesses advanced legislation and treatment works, managing river quality remains a massive challenge due to outdated sewer infrastructure, rapid population growth, and high costs of retrofitting nationwide drainage networks.

❌ Common Errors

• Direct lifting: Copying "raw sewage, microplastics and farm waste" without explaining their impacts receives zero credit for AO3.
• Forgetting "Own Understanding": Only discussing what is written in the box caps your mark at 4/6.
• No evaluative verdict: Failing to answer "To what extent do you agree?" in an opening or closing statement.
