Theme : essay: writing about problems and solutions

One Problem/Cause & Solution or Two?
Most questions will state problems, causes and solutions in the plural, that is, more than one. However, it is acceptable to write about just one.
This will give you an essay of just over the minimum 250 words. To write about two problems/causes and solutions will require you to write between 350 and 400 words which are a lot to plan and write in the 40 minutes allowed.
It is better to fully develop one problem/cause and solution than ending up with one idea missing an explanation or an example because you run out of time.
The step-by-step essay structure I’m going to show you includes one problem and solution but you can write about two if you feel able to or more comfortable doing so.
How To Plan IELTS Problem Solution Essays
Here’s the question we’re going to be answering in our model essay followed by the 3 steps of the planning process.
One problem faced by almost every large city is traffic congestion.
What do you think the causes are? What solutions can you suggest?

• 
  Analyse the question
  

• 
  Generate ideas
  

• 
  Identify vocabulary
  

# 1 Analyse the question
This is an essential step in the planning process and will ensure that you answer the question fully. It’s quick and easy to do. You just need to identify 3 different types of words:
1. Topic words
2. Other keywords
3. Instruction words

Topics words are the ones that identify the general subject of the question and will be found in the statement part of the question.

One problem faced by almost every large city is traffic congestion.

So, this question is about ‘traffic congestion’.

Many people will do this first step of the process and then write about the topic in general. This is a serious mistake and leads to low marks for task achievement.
What we need to do now that we know the general topic, is to understand exactly what aspect of traffic congestion we're being asked to write about.
The other keywords in the question tell you the specific topic you must write about. 
One problem faced by almost every large city is traffic congestion.

By highlighting these words, it’s easy to see that you are being asked to write about the problem of traffic congestion in large cities. Your essay must only include ideas relevant to these ideas.

The instruction words are the question itself. These tell you the type of IELTS problem solution essay you must write. This is a ‘causes and solutions’ question.
What do you think the causes are? What solutions can you suggest?
