IELTS writing task 2: How to write a causes solution essay

Step by step guide to writing an IELTS causes solution essay.

Updated : January 2024

A common type of IELTS task 2 essay is a problem solution or causes solution essay. Here you will need to write about the causes of the problem in main body one and recommendations or possible solutions that could solve the issue in main body two. I could have a 3rd body paragraph but I prefer the 2 main body approach.

In this lesson we will look at:

1. A good structure for a causes/problem solution essay. 2. How to analyse the question. 3. Tips on thinking of ideas for the essay. 4. Getting ideas effectively. 5. How to paraphrase the question and write a good introduction. 6. How to build main body paragraphs. 7. How to write an effective conclusion. 8. Model Answer.

In this type of IELTS essay, you can either write about 2 problems and 2 solutions or just 1 problem and 1 solution as long as you develop and extend your ideas. Both are fine there is no one particular magic structure that will guarantee a high band score.

Example of one problem one solution structure.

Analyse the question.

This is the first thing that needs to be done before getting ideas or writing anything. Let’s look at the question.

All over the world, societies are facing a growing problem with obesity. This problem affects both children and adults. What are the reasons for this rise in obesity, How could it be tackled?

Keywords: all over the world, societies, a growing problem, obesity, affects children and adults,

(The general topic is about obesity, however, we need to focus on the issues. Keywords such as “all over the world” “societies” ” affects children/adults” “growing problem” It is important to write about the issues by looking at the keywords, not just a general essay on obesity.)

Instruction words: These words show what kind of essay you will need to write, there are 5 essay types and each structure is different. In this case, the instruction words are: “what are the reasons for this? ” and “how could it be tackled?” . I have to write about the reasons for the problem and how can the problem be solved. This is a causes solution essay.

Tips on getting ideas for the essay.

1. listing pros and cons or problems and solutions:.

This idea might work well for a problem solution essay or an advantage disadvantage essay but for the other types of essay, it might not work very well. You just list problems on the left and solutions on the right. (I will use this method in this lesson.) but remember we only choose one or two problems and solutions to write about.

This took me about 2 minutes to list them, so now I need to select just 1 or 2 problems and 1 or 2 solutions and write about those. I do not need all these ideas, be selective here.

Important: do not just write a list of problems in the essay. You have to explain the causes of the problem and give specific examples and a suggestion for what action should be taken in the body paragraphs. You only need to write about 1 or 2 problems and suggest solutions. Don’t waste time brainstorming ideas or going into too much detail because you will not have time.

2. Asking questions to yourself:

This technique is very useful for getting ideas quickly, remember that you don’t have much preparation time before writing. So you write a statement and ask yourself questions, like having a conversation with yourself. This works well for an opinion essay or discussion essay.

By the way, you can just use one problem and one solution and still get a Band 7 if the essay is well supported and developed.

You have a little conversation with yourself to get ideas and then write some notes. Imagine you are with a friend and they are having a conversation with you about this topic. Keep it short though because you have to now think of paraphrasing the question and writing a thesis statement.

Giving Examples

You do not need to be an expert on the topic, but you need to give an opinion and support it with specific examples. Another thing to bear in mind is the specific examples you give do not have to be accurate. For example, if I say “the consumption of fast food in the UK has risen by 24% since 2002 “ that sounds fine, but if I say “ it has risen by 98% “ then that just doesn’t sound believable.

Tip: The IELTS test is not a general knowledge test. It is designed to test your English ability and the way you can back up your arguments with examples. Many students are scared and think their facts, opinions or statistics will be cross-checked. The examiner is not going to check online to see if your facts or statistics are correct, they just don’t have time to do that.

How to paraphrase the question and write an effective introduction.

Now it is time to paraphrase the question for the introduction and add a thesis statement. Here is the question again.

Paraphrased version:

Nations worldwide are dealing with the increasing issue of obesity. This is a cause for concern for all age groups.

These are the words and phrases that I have paraphrased using synonyms.

• All over the world – Worldwide
• Societies – Nations
• Are facing a growing problem with.. – Are dealing with the increasing issue of…
• This problem affects both children and adults – This is a cause for concern for all age groups

Have you noticed that I didn’t paraphrase everything?  It is not necessary to change every single word. Also, I changed the phrase “All over the world, societies are….” to a much simpler “ Nations worldwide” . It’s not just about paraphrasing words with synonyms the grammar can be slightly altered too. Now I need to state the causes of the problems and possible solutions in the Thesis statement.

The Thesis Statement.

There are two main causes, overconsumption of fast food and a lack of exercise. Possible solutions would be a government tax on fast food and special incentives on gym membership to get people exercising.’

Keep the thesis statement short and to the point. Another method is to state the causes of the problem and refer to the fact that there are possible solutions to the issue. This means you will have a much more concise thesis statement. Example below.

This is caused by overconsumption of fast food and a lack of exercise, however, some steps can be taken to resolve this.

Remember: Your main body paragraphs will reflect the thesis statement so you must plan your thesis statement well.

Here is the introduction in full.

Nations worldwide are dealing with the increasing issue of obesity. This is a cause for concern for all age groups. There are two main causes, overconsumption of fast food and lack of exercise. Possible solutions would be a government tax on fast food and special incentives for gym membership to get people exercising.

This introduction is around 54 words. Keep it concise it is not necessary to have a long introduction.

Main body paragraphs.

I have chosen 2 key problems which are fast food and lack of exercise so I want to stick with those and not go off onto another topic. Do not suddenly change your ideas in the middle of writing you will lose time. Take a look at the idea below.

One of the reasons people are becoming obese these days is that they eat junk food like hamburgers and chips. The solution is for the government to raise taxes on fast food.

Is there enough detail here? Is there anything missing from this paragraph? How can I improve it? The answer is that I need more detail and a specific example, not just a general example . I need to explain what can be done to solve the problem. I can also write about what the result of the solution could be.

In this case, I will go with 2 causes 2 solutions

Key: Green = main topic sentence, Blue = give an explanation, Purple = give an example,  Orange = give a possible solution,  Grey = result of the possible solution (you don’t have to use this though)

• One of the reasons that people are becoming overweight these days is that they are eating more junk food, ready meals and convenience food rather than cooking healthy meals at home. This is because many people tend to lead a busy life and after a long day at work it is easier to just buy ready meals in the supermarket or get a takeaway. For instance, In the UK sales of these types of foods have risen dramatically since 1990. This is due to busy people seeing cooking at home as time-consuming. To tackle this issue the government should take steps to increase tax on high fat, high sugar or unhealthy foods. Therefore consumers would think twice about the foods they consume, which could lead to them losing weight.

Now I will use the same technique to write the main body 2 paragraph about lack of exercise.

• Another problem that needs to be considered is the lack of exercise. As a result of leading a busy life or work pressures, many people are just too tired to go to the gym or join a sports club. For example, after a hard day at work, most people prefer to just come home and sit in front of the TV. It goes without saying that when people have time off they tend to relax rather than going to a gym. One possible solution is for employers to consider the health and well being of their employees and offer in-house company gyms or special incentives, such as discounts to join a sports or fitness club. If this is implemented it would have a positive effect on peoples health and a reduction in weight gain.

Some key phrases for introducing the causes of the problem and giving solutions

• Problem: One of the main reasons for…..   Solution : To tackle this issue…..
• Problem: Another problem to consider is…  Solution : One possible solution is….
• Problem : One main cause of…….   Solution : The way forward could be to…..
• Problem: A particular cause for concern is …   Solution: To solve this problem…

Examples for introducing problems: 


• One of the main reasons for people becoming overweight these days is that they are eating junk food, ready meals and convenience food…
• Another problem that needs to be considered is the lack of exercise…..

Grammar for showing possible results/outcomes: 


• Therefore, consumers would think twice about the food they consume…..
• As a result, this would have a positive effect on peoples health…..
• Unless action is taken, the problem will get worse……
• If the government takes steps to address the issue, the problem could be resolved…
• This would result in a reduction of obesity/This would lead to a reduction in obesity…

Key point on giving examples in body paragraphs: Something that is important for backing up your supporting points is giving specific examples, such as “In the UK sales of these types of food have risen dramatically since 1990” . You can give statistics but they are not really necessary. The examiner is not going to google your information and check. The aim of this is to show how you can use examples to back up your points.

How to write a good conclusion.

Now let’s take a look at the conclusion. Here you need to briefly summarise the 2 problems and 2 solutions with a recommendation or prediction sentence.

Key: Green = cohesive device,  Orange = summarise the 2 problems,  Blue = summarise the 2 solutions,  Purple = recommendation or prediction sentence

• In conclusion, being overweight is an increasing issue because of consumption of fast food, convenience foods and lack of exercise due to work commitments. The government needs to look at taxing fast food and companies should set up incentives for gyms, sports or fitness clubs. Unless this issue is tackled soon, then the problem of obesity will lead to a higher mortality rate in the future.

The last sentence is optional (the recommendation prediction sentence) but this is a good idea to include if you think the essay is under 250 words.
 The conclusion should briefly repeat the main points you were writing about in the main bodies of the essay. Be sure to keep the conclusion short and simple, about 3 sentences is enough.

You must write a conclusion, If you do not write a conclusion you will lose a Band score in task response. One useful method is to paraphrase your introduction in the conclusion.

Examples of cohesive devices to conclude.

• In conclusion
• To conclude

Just choose one of these in the conclusion. Some words that should not be used to conclude are ‘ All in all, Finally, Lastly, in the end, In a nutshell, I reckon … ‘ don’t use these, they are informal or are inappropriate.

Model Answer (2 causes 2 solutions)

Nations worldwide are dealing with the increasing issue of obesity. This is a cause for concern for all age groups. There are two main causes, over-consumption of fast food and lack of exercise. Possible solutions would be a government tax on fast food and special incentives for gym membership to get people exercising.

One of the reasons that people are becoming overweight these days is that they are eating more junk food, ready meals and convenience food rather than cooking healthy meals at home. This is because many people tend to lead a busy life after a long day at work it is easier to just buy ready meals in the supermarket or get a takeaway. For instance, In the UK, sales of these types of foods have risen considerably since 1990, this is due to busy people seeing cooking at home as time-consuming. To tackle this issue the government should take steps to increase the tax on high fat, high sugar or unhealthy foods. Therefore, consumers would think twice about the foods they consume, which could lead to them losing weight.

Another problem that needs to be considered is the lack of exercise. As a result of leading a hectic life with pressures at work, many people are just too tired to go to the gym or join a sports club. For example, after a hard day at work, most people prefer to just come home and sit in front of the TV. Furthermore, when people have time off they tend to relax rather than go to a gym. One possible solution is for employers to consider the health and well being of their employees and offer in-house company gyms or special incentives, such as discounts to join a sports or fitness club. If this is implemented it would have a positive effect on peoples health and a reduction in weight gain.

In conclusion, being overweight is an increasing issue because of consumption of fast food, convenience foods and not enough exercise due to work commitments. The government needs to look at taxing fast food and companies should set up incentives for gyms, sports or fitness clubs.

Note:   The essay doesn’t have to be this long , I did this for example purposes only, aim for around 260 to 290 words as you will not have the time to write a long essay in the exam.

There is no magic structure that can guarantee you a high band score for an IELTS essay. You can have 1 problem 1 solution as long as it is well supported or 2 problems 2 solutions or a 3rd body paragraph.

Just work with whatever you feel comfortable with. The essay must have an introduction and a conclusion though, and no more than 3 body paragraphs.

Hi, I got a bit confused. you have said the structure for this type of question, at the top of this page in a box, that in main body one, we bring the problems, and in the main body two we bring solutions, but in your Model Answers you have brought one problem and its solution in the main body 1, and the second problem and its solution in the main body two. which structure is valid then?

The one problem one solution is easier to write for many people, so i recommended that… the model answer just shows a longer essay type with 2 problems and 2 solutions but that tends to be a challenge for some people to write about as they run out of time. Both structures are ok to use, whatever you feel comfortable with.

So that means, if I wrote two problems in body 1 and their solutions in body 2, that is still OK?

yes thats fine, but try to keep the essay concise.

I would like to appreciate the way you explained each and everything in a very simple and concise way. Appreciated.

Thanks, glad it was useful.. Ray
