The prompt

One prompt, followed from reading it to having it written

Everything below answers this. The highlighted words are the instruction — the part that decides the shape of the whole essay, and the part most people skim.

IELTS-style prompt

Large quantities of food are wasted by households. Why does this happen, and how can the amount of waste be reduced?

How you recognise it

The instruction, and the one mistake that costs most

Instruction signal: What are the causes/problems? What measures/solutions can be taken?

What it must answer: Identify the requested causes or problems and propose solutions that directly address them. Some prompts request only one of these combinations.

Most common misread
Memorising a causes-and-solutions template when the actual prompt asks for problems and measures, or causes and effects.

Official format versus WeLearn strategy

Official format: IELTS Academic Writing Task 2 asks for an essay of at least 250 words in response to a question. The five question families are WeLearn teaching categories, not official IELTS names.

WeLearn strategy: This page collects the steps of the full course filtered to one question type, so that a student who only needs this one can follow the whole path in order.

Step 1

Read the prompt before you plan anything

Six questions you put to the prompt, in this order. They are the same six for every Task 2 prompt you will ever see — that is what makes them worth learning. Answer each one before you open it.

1TopicWhat situation is this prompt about?

Cover the highlighted instruction with your hand and read only what is left. That is the topic — and it is the part that matters least, which is why most people spend the most time on it.

See the answer for this prompt

food waste

2InstructionWhat am I being told to produce?

The highlighted words, and nothing else. Not the topic, not how many views appear before it. Every decision below follows from this one sentence.

See the answer for this prompt

What are the causes/problems? What measures/solutions can be taken?

3ScopeHow much room does that instruction leave me?

The exact wording. “To what extent” allows a degree — largely, partly. “Do you agree” does not. “Outweigh” forces a verdict; “advantages and disadvantages” forbids one. One word decides.

See the answer for this prompt

Answer why and how.

4Your answerWhat do I actually think, in one sentence?

Nowhere in the prompt. This is the first row you supply, and if you skip it now you will discover halfway through Body 2 that you never decided.

See one answer that works

A personal opinion is not always required. The thesis should define the diagnostic and solution route.

5Body 1What is the strongest reason for that answer?

Also yours. The test is whether it supports the answer above — not whether it is true about the topic. A true statement that does not support your answer belongs in someone else's essay.

See one answer that works

purchasing habits and date labels.

6Body 2What is the second reason, and is it genuinely different?

Yours as well. If you can rewrite Body 2 using Body 1's sentences, you have one reason written twice, and the examiner will read it as one.

See one answer that works

planning and clearer labels.

Rows 1 to 3 are in the prompt: two readers should get the same answer. Rows 4 to 6 are not — they are yours, and two good essays on this prompt can disagree completely.

Step 2

The introduction

What this paragraph has to do, and how you get there from the prompt above.

Worked example
1 · What the prompt forces here

Answer why and how.

2 · The decision you make

Body 1: purchasing habits and date labels. Body 2: planning and clearer labels.

3 · What comes out of it

The blocks below, in this order.

Optional contextGive the scale or the cost of the problem in one concrete sentence.

Most discarded food is thrown away long before it becomes unsafe to eat.

Paraphrase

Household food waste remains widespread despite its financial and environmental costs.

Scope thesisName the exact parts the essay will analyse.

The problem largely results from poor purchasing decisions and confusion over date labels, both of which can be reduced through practical consumer guidance and clearer packaging.

Why this one answers the question

The causes and solutions are paired in one precise sentence.

No unnecessary personal opinion is invented.

Watch for: Memorising a causes-and-solutions template when the actual prompt asks for problems and measures, or causes and effects.

Step 3

Body 1

What this paragraph has to do, and how you get there from the prompt above.

Worked example
1 · What the prompt forces here

Body 1 carries the first reason you committed to when you read the prompt: purchasing habits and date labels.

2 · The decision you make

Answer why: weak planning and misunderstood date labels.

3 · What comes out of it

The blocks below, in this order.

Problem or causeAnswers the first requested problem, cause or effect.

Household food waste often begins with poor purchasing decisions and confusion about product labels.

Specific factorNames the precise condition driving the issue.

Shoppers may buy more than they can use when promotions reward quantity or meals have not been planned.

Cause-and-effect chainExplains how the factor creates the stated consequence.

Usable food may then be discarded because a quality label is interpreted as an immediate safety deadline.

IllustrationMakes the causal chain concrete.

For example, an unopened product can be thrown away solely because its best-before date has passed, even when correct storage has preserved it.

Task linkReturns to the exact first instruction.

Much domestic waste is thus created before food is ever prepared.

Watch for: Moving directly to recycling, which does not explain why edible food is purchased and discarded.

Step 4

Body 2

What this paragraph has to do, and how you get there from the prompt above.

Worked example
1 · What the prompt forces here

Body 2 carries the second reason you committed to when you read the prompt: planning and clearer labels.

2 · The decision you make

Answer the second instruction with practical ways to reduce household food waste.

3 · What comes out of it

The blocks below, in this order.

Solution claimNames a response that matches the earlier problem or cause.

Household food waste can be reduced by making purchasing and storage decisions more deliberate.

ImplementationExplains what people or institutions would actually do.

Clear meal plans, realistic portion sizes and visible date labels help consumers use food before buying replacements.

MechanismShows how the response addresses the cause.

These measures interrupt the cycle in which excess products are forgotten and discarded.

IllustrationDemonstrates the response in a plausible setting.

For example, a household that plans three evening meals can buy the required ingredients instead of choosing a large promotional bundle.

Expected resultStates the relevant improvement the solution should produce.

Better planning therefore directly limits the unnecessary purchasing that drives domestic waste.

Watch for: Proposing restaurant or farm policies when the question concerns households.

Step 5

The conclusion

What this paragraph has to do, and how you get there from the prompt above.

Worked example
1 · What the prompt forces here

The conclusion has to end on the answer you committed to when you read the prompt: A personal opinion is not always required. The thesis should define the diagnostic and solution route.

2 · The decision you make

Compress the diagnosis and restate the response that actually addresses it.

3 · What comes out of it

The blocks below, in this order.

Problem synthesisCompresses the main cause or problem established in the essay.

Overall, household food waste often begins with excessive purchasing and poor storage decisions.

Matched responseRestates the solution that directly addresses that diagnosis.

Realistic meal planning, portion control and clearer use-by information can directly interrupt this avoidable cycle.

Watch for: Adding a new solution that the body paragraphs never developed.

Step 6

The connectors this type leans on

Every family is useful somewhere. These are the ones this question type needs most.

261 words on the prompt below. Each paragraph is labelled with the job it does — the same jobs you just read, in the same order.

Food waste

Large quantities of food are wasted by households. Why does this happen, and how can the amount of waste be reduced?

Introduction

Most discarded food is thrown away long before it becomes unsafe to eat. Household food waste remains widespread despite its financial and environmental costs. The problem largely results from poor purchasing decisions and confusion over date labels, both of which can be reduced through practical consumer guidance and clearer packaging. This essay identifies the main causes of household waste and then sets out the purchasing and storage measures most likely to reduce it.

Reframe the prompt, state the position, and preview what each body paragraph will argue.
Body 1

Household food waste often begins with poor purchasing decisions and confusion about product labels. Shoppers may buy more than they can use when promotions reward quantity or meals have not been planned. Usable food may then be discarded because a quality label is interpreted as an immediate safety deadline. For example, an unopened product can be thrown away solely because its best-before date has passed, even when correct storage has preserved it. Much domestic waste is thus created before food is ever prepared.

Answer why: weak planning and misunderstood date labels.
Body 2

Household food waste can be reduced by making purchasing and storage decisions more deliberate. Clear meal plans, realistic portion sizes and visible date labels help consumers use food before buying replacements. These measures interrupt the cycle in which excess products are forgotten and discarded. For example, a household that plans three evening meals can buy the required ingredients instead of choosing a large promotional bundle. Better planning therefore directly limits the unnecessary purchasing that drives domestic waste.

Answer the second instruction with practical ways to reduce household food waste.
Conclusion

Overall, household food waste often begins with excessive purchasing and poor storage decisions. Realistic meal planning, portion control and clearer use-by information can directly interrupt this avoidable cycle.

Compress the diagnosis and restate the response that actually addresses it.

Preguntas frecuentes

Lo que se pregunta sobre este tipo de ensayo

¿Problem-solution essay es una tarea oficial separada en IELTS Writing Task 2?

No como ruta oficial independiente. IELTS Writing Task 2 pide escribir un ensayo de al menos 250 palabras en respuesta a una pregunta. WeLearn separa problem-solution como categoría de práctica porque muchos prompts piden explicar causas, problemas, soluciones o medidas.

¿Qué debe incluir un ensayo problem-solution fuerte?

Debe identificar un problema específico, explicar por qué ocurre o por qué es importante, proponer una solución realista y conectar esa solución con el problema. No basta con nombrar medidas generales.

¿Puedo escribir solo soluciones si el prompt menciona problems and solutions?

No. Si la pregunta pide both problems and solutions, debes cubrir ambos lados de forma explícita. Omitir problemas o soluciones puede afectar Task Response.

Problem and solution prompt bank

Two original prompts to train problem-and-solution essays

Official format: IELTS Academic Writing Task 2 requires a response of at least 250 words to the given prompt. WeLearn strategy: this route trains the link that decides this type: every solution you propose has to answer a problem or a cause you named earlier, and the prompt decides which of the two it asked for.

Problem-solution

Prompt food waste

Practise this type

Many households throw away large amounts of food every week. Why does this happen, and what measures could reduce the problem?

Practice objective

Connect causes with realistic solutions instead of writing two unrelated lists.

Thesis or key move

Food waste is mainly caused by poor planning and confusion about freshness labels, so solutions must make buying and storing food easier for households.

Four-step plan
  1. Introduction: paraphrase food waste and preview causes plus solutions.
  2. Body 1: explain causes such as overbuying, unclear date labels and poor meal planning.
  3. Body 2: propose linked solutions such as label education, smaller package options and planning apps.
  4. Conclusion: restate that reducing waste needs both information and practical purchasing changes.
Useful language
One major cause is...This problem is reinforced by...A practical response would be...This measure would address the cause by...
Common trap

Giving solutions that do not match the causes.

Review checklist
  • Each solution responds to a cause I already explained.
  • I avoid vague solutions such as government should educate people without detail.
  • I include household-level behavior, not only national policy.
  • My conclusion links cause and solution.

Problem-solution

Prompt urban loneliness

Practise this type

People living in large cities often report feeling lonely despite being surrounded by others. What causes this problem, and what can be done to address it?

Practice objective

Explain social causes and propose community-level solutions with clear mechanisms.

Thesis or key move

Urban loneliness often results from weak local routines, so solutions should create repeated, low-pressure opportunities for residents to meet.

Four-step plan
  1. Introduction: paraphrase urban loneliness and state that both lifestyle and city design matter.
  2. Body 1: explain causes such as long commutes, temporary housing and lack of shared spaces.
  3. Body 2: propose solutions such as local events, mixed-use public spaces and workplace flexibility.
  4. Conclusion: summarize that cities need social infrastructure, not only more population density.
Useful language
Although cities are crowded, many residents...A deeper cause is...This could be addressed by...The value of this solution is that...
Common trap

Explaining loneliness as only an individual attitude and ignoring urban conditions.

Review checklist
  • I explain why proximity does not automatically create connection.
  • My solutions are specific enough to imagine.
  • I connect city design, work routines or community spaces to loneliness.
  • I do not blame residents without evidence.
