A problem and solution essay becomes much easier when you stop treating it as a test of “big ideas.” IELTS examiners are not looking for a perfect policy that could transform a country overnight. They are looking at how well you answer the question, develop relevant ideas, organise the response and use English. A modest solution explained clearly is stronger than a dramatic promise with no connection to the problem.
This guide takes you through the whole process. You will learn how to recognise different question wordings, avoid confusing a cause with a consequence, build a realistic solution, organise your paragraphs and check your work. The examples use everyday topics, so you can focus on the thinking and language that transfer to other questions.
IELTS Writing Task 2 asks you to respond to a point of view, argument or problem in at least 250 words. British Council guidance says you may be asked to propose solutions and support your response with reasons and relevant examples. IDP also stresses that learners should read the exact prompt instead of forcing every question into a memorised formula.
Start with the instruction
How to understand a problem and solution question
The topic sentence gives you the situation, but the final question tells you what to write. Circle or copy the key task words before you brainstorm. A prompt may look like a problem–solution topic while asking about causes and effects instead. If you answer the wrong pair of questions, polished grammar cannot fully rescue the response.
Problems + solutions
What problems does this cause, and what measures could solve them?
Explain harmful results, then actions that reduce them.Causes + solutions
Why is this happening, and what can be done about it?
Explain reasons, then actions that address those reasons.Causes + effects
What are the reasons for this trend, and how does it affect society?
There is no request for solutions. Do not add a solution paragraph.Cause, central issue and problem are not the same
Imagine a question about the growing amount of household rubbish. Heavy use of disposable packaging is a cause. The growing amount of rubbish is the central issue named in the prompt. Overloaded landfill sites and higher collection costs are problems that follow. Charging producers for hard-to-recycle packaging could be a solution. Seeing the direction prevents circular statements such as “The problem with household waste is that there is too much household waste.”
When the prompt asks for “problems,” focus mainly on the harmful consequences. You can briefly mention a cause if it helps the explanation, but it should not take the place of the requested answer. When it asks for causes, explain why the situation happens. The wording decides your job.
Prefer depth to a long list
How to choose ideas you can explain
You may think of five problems in one minute. Do not automatically use all five. A strong body paragraph needs space to explain what happens, who is affected and why the result matters. Choose one or two main ideas that are different from each other and easy to develop. Two clear chains are usually more useful than four undeveloped labels.
Is it specific?
“It affects society” is too broad. “Unpredictable travel makes workers late” gives you something real to explain.
Is it relevant?
If the question focuses on young people, your main explanation must clearly return to that group.
Can you show the chain?
You should be able to explain what leads to the result, not simply call it serious.
Can a solution reach it?
A useful idea has a possible point of action. Avoid a problem so vague that no responsible actor can affect it.
Turn a label into a developed problem
Suppose the topic is unaffordable housing near large cities. The label “long commutes” is only the beginning. Explain the chain: workers who cannot afford homes near employment centres move farther away; they then spend more money and time travelling; unpredictable journeys may make them late or force them to reject suitable work. Now the reader can see the affected group, the mechanism and the practical consequence.
Too thinOne problem is long commuting, which is very bad for workers and society.
DevelopedWhen lower-paid workers cannot rent near major employment areas, they often move to distant suburbs. Their longer and less predictable journeys increase travel costs and may make regular punctuality difficult, limiting the jobs they can realistically accept.
Make the connection visible
How to match a solution to the problem
A solution is relevant only if it changes something in the chain you have described. Ask four practical questions: Who can act? What should they do? How will the action change the cause or consequence? Why is it realistic enough to discuss? This removes vague advice and makes your reasoning easier to follow.
| Problem described | Weak response | Better matched response |
|---|---|---|
| Buses arrive too rarely, so commuters depend on cars. | People should care more about pollution. | Transport authorities could add services on the busiest routes at commuting times. |
| Families do not understand local recycling labels. | The government should solve waste. | Councils could use one label system and print picture-based sorting instructions on bins. |
| Children buy sugary drinks easily at school. | Parents should exercise more. | Schools could replace high-sugar drinks in vending machines and provide free drinking water. |
Notice that the better responses name the actor and action. They also touch the exact point where the problem develops. This does not mean you must prove that the action will remove the issue completely. You can write that a measure would reduce, limit, ease or prevent some cases of the problem. Honest scope sounds more convincing than “This will solve the problem once and for all.”
Make “education” and “awareness” concrete
Learners often use public education as a universal solution. It can work, but only when you explain what people need to learn, who will teach it, how they will receive the message and what behaviour may change. For example, “Schools should raise awareness of health” is thin. A clearer proposal is: “Schools could teach pupils how to read the sugar content on drink labels during health lessons, helping them compare products before buying them.” The second version contains an audience, content, delivery method and intended decision.
Write one problem sentence, then explain exactly what changes because of your proposed action.
Choose the clearest order
How to structure the essay
There is no single officially required paragraph pattern. Your structure should make every part of the answer easy to find and every problem–solution connection easy to understand. Two arrangements work especially well.
Grouped structure
- Introduction: introduce the issue and preview your answer
- Body 1: explain the main problems or causes
- Body 2: explain the matching solutions in the same order
- Conclusion: summarise the problems and responses
Use this when the problems share a cause or the instruction clearly separates the two jobs.
Paired structure
- Introduction: introduce the issue and preview your answer
- Body 1: explain problem A and its solution
- Body 2: explain problem B and its solution
- Conclusion: summarise both pairs
Use this when each problem has its own distinct response.
If you use the grouped structure, keep the order consistent. Explain problem A before problem B, then discuss solution A before solution B. If you reverse the order without clear signposting, the reader has to work harder to find the links. If you use the paired structure, make the move from problem to response explicit: “One practical way to reduce this difficulty would be…”
What belongs in each part?
Your introduction can be short. Paraphrase the situation accurately and tell the reader what the essay will address. Do not copy full sentences from the prompt, announce memorised phrases or explain all your ideas before the body begins. Each body paragraph should have a clear main point, an explanation and a result or example. The conclusion should bring the answer together without introducing a new cause, problem or policy.
Situation + direct preview
Main claim → why/how → consequence or example
Responsible actor → action → mechanism → expected improvement
Concise summary, no new idea
Follow the reasoning
Worked example: childhood obesity
A growing number of children are becoming overweight, which can create serious health concerns. What are the causes of this problem, and what measures could be taken to address it?
Give reasons for your answer and include relevant examples from your own knowledge or experience.This question asks for causes and measures. It does not ask you to list the medical effects of obesity. Before writing, choose causes that lead to actions you can explain. Here is one possible plan:
Availability makes unhealthy choices frequent, not occasional.
The action changes the choice available during the school day.
Children may spend more free time indoors and move less.
The action improves safe access rather than merely telling children to exercise.
Sample introduction
Childhood obesity is becoming more common in many places, partly because children’s everyday surroundings make unhealthy eating and inactive leisure easy. Schools and local authorities can respond by improving the food and physical activities available during and after the school day.
The first sentence introduces the issue and gives a clear direction. The second previews responsible actors and the type of response. It does not promise to discuss every possible cause.
Sample cause paragraph
One important cause is the easy availability of inexpensive food and drinks with a high sugar content. When these products fill school vending machines and nearby shops, children can consume them regularly without recognising how much sugar they contain. In addition, children living in crowded areas may have few safe places to play outside, so passive activities such as watching videos become the simpler option after school. Together, these conditions make excess energy intake and low physical activity part of an ordinary routine.
The paragraph develops two causes but connects them through the idea of the child’s daily environment. It explains how each cause influences behaviour. It does not rely on an invented percentage or an extreme claim.
Sample solution paragraph
Schools could first replace the most sugary vending-machine products with water and lower-sugar alternatives, while teaching pupils how to compare simple nutrition labels. This would improve the immediate choice and help children make informed decisions elsewhere. Local councils could also keep selected sports grounds open under supervision in the late afternoon. Safe, low-cost access would make active leisure practical for families who lack private space. These measures would not remove every cause of obesity, but they would improve two parts of the environment that shape children’s routines.
Every response points back to a stated cause. The paragraph explains both implementation and expected change. The final sentence limits the claim sensibly. This is the kind of practical reasoning you can reproduce with different topics.
Sample conclusion
In summary, children are more likely to gain excess weight when unhealthy products and inactive routines are the easiest daily options. Changing what schools sell and expanding safe opportunities for exercise can therefore reduce these pressures in a direct and realistic way.
Let grammar show the logic
Useful language for causes, effects and solutions
You do not need unusually academic words. You need accurate language that shows direction. Learn patterns as complete pieces, because similar phrases often use different grammar.
| Purpose | Useful patterns | Example |
|---|---|---|
| Show a cause | stems from; is driven by; arises when; because | The difficulty stems from limited access to reliable buses. |
| Show an effect | leads to; results in; leaves; places pressure on | Long waits lead to greater car use. |
| Name an actor | councils could; employers can; schools should | Transport authorities could increase peak-time services. |
| Show purpose | to; so that; in order to | More services are needed so that commuters have a reliable alternative. |
| Show the result | thereby; which would; as a result | Fares could be capped, thereby reducing the cost barrier. |
| Limit a claim | reduce; ease; help prevent; may improve | The measure may ease congestion on the busiest routes. |
Watch two easily confused patterns: a result results from its cause, while a cause results in an effect. Also check what words such as this and they refer to. If two possible ideas appear in the previous sentence, repeat the exact noun. Clear reference is more valuable than avoiding every repetition.
Examples without invented evidence
You are allowed to use relevant examples from your knowledge or experience. You do not need to invent a university study, government report or precise statistic. An honest illustration is enough: “For example, an employee may reject a suitable job if the daily fare and travel time are unsustainable.” The example shows the consequence without pretending to be published research.
Repair relevance before vocabulary
Common mistakes and how to correct them
Repeating the topic as the problem
Weak: The problem with traffic congestion is that roads are congested.
Better: Unpredictable delays make workers late and increase delivery costs for local businesses.
Giving a slogan instead of a solution
Weak: Governments must take action and raise awareness.
Better: Councils could show real-time bus arrival information at stops, making the service more predictable for commuters.
Choosing the wrong actor
Weak: Individuals should build more affordable homes.
Better: Planning authorities could require some below-market units in large developments.
Answering a different question
Weak: A causes-and-solutions essay spends a full paragraph on harmful effects.
Better: Label the two requested jobs in the plan and check every topic sentence against them.
Listing without explaining
Weak: The causes are advertising, prices, parents and technology.
Better: Select the strongest one or two and show how they shape behaviour.
Promising a complete cure
Weak: This policy will eliminate the issue forever.
Better: This measure could reduce the most common barrier, although other causes would remain.
Check your understanding
Practice exercises
Exercise 1: identify the job
For each instruction, decide whether you need to write about causes, problems, effects or solutions.
- Why are many town centres losing small independent shops, and what can be done to support them?
- What difficulties does excessive screen use create for families, and how might these difficulties be reduced?
- Why has food delivery become more popular, and what effects does this trend have on local communities?
Show the answers
1: causes and solutions. 2: problems and solutions. 3: causes and effects—no solution is requested.
Exercise 2: find the better match
Problem: university students avoid seeking help for stress because appointments are difficult to arrange and they fear being judged. Which response fits better?
- Universities should make students more aware that health is important.
- Universities could offer confidential online booking and short drop-in sessions, reducing both the practical and social barriers to asking for support.
Show the answer
The second response is stronger. It names an actor and two actions, then links each action to a barrier already described.
Exercise 3: build one paragraph
Choose a familiar topic. Write four planning notes: the exact problem or cause, the affected person, the responsible actor and the action. Then write a paragraph that explains the connection. Read it once with the solution covered. Is the problem fully explained? Next, read only the problem and solution sentences. Can you see what changes between them?
Your final five-minute check
- I answered both parts of the exact instruction.
- I did not confuse a cause with a harmful consequence.
- Each main idea is explained, not merely named.
- Every solution has a realistic actor and action.
- I showed how the response changes the problem.
- My paragraphs follow a clear order.
- My examples illustrate rather than pretend to prove.
- My conclusion adds no new idea.
- Cause-and-effect grammar points in the correct direction.
- I checked sentence boundaries, verbs, articles, reference and punctuation.
If your logic is clear but your language is simple, keep it clear. Accurate everyday English can carry a thoughtful answer. Improve range gradually; do not replace a sentence you control with one you cannot check.
