IELTS Speaking Part 3: follow the steps (in your head)

 When answering questions in part 3 of the speaking test, you should have three (or maybe four) steps that you follow.

Practise checking off these steps in your head as you answer:

1. Give a direct answer to the question
2. Explain with a reason or reasons
3. Give an example (e.g. a personal example)
4. Explain the opposite or an alternative (you don't always need this step)

For example, here's a question from a recent lesson:

Why do you think people like taking photos of themselves and others?

Here's my answer, following the first three steps above:

(Direct answer) I think the main reason why people take photos of themselves and their friends and family is to collect memories. (Explain) What I mean is that photos are like souvenirs that remind us of special moments in the past; people like looking back over their lives and seeing what they were doing or how young they looked at a particular time. (Example) My niece is a good example; she takes 'selfies' whenever she goes somewhere interesting, and she loves to look through them with her friends.

Task:
My answer is already long enough, but can you add the fourth step?
