Case Examiner: Why do people have hobbies? Speaker: I like | Leaders Academy

Case
Examiner: Why do people have hobbies?
Speaker: I like watching TV because it has many entertaining programs.

Examiner: Why do people have hobbies?
Speaker: Well, TV relaxes me. When I was watching it last night... [and so on].

Case , the Examiner has asked a general question about peoplegenerally, not the speaker personally. However, the speaker keeps trying to answer personally. There is no 'task fulfilment' category in IELTS speaking, but the more experienced examiner will realise that you are speaking personally because it is easier. The examiner will realise that you do not have the English ability to handle general or unfamiliar topics.

You may be IELTS Vocabulary Five:
Has some words for familiar and unfamiliar topics .

but you are not IELTS Vocabulary Six: Has words for a wide variety of topics.

So, when asked a general question, if you can only speak personally, or prefer to explain a point through a personal example which is often very good, then you need to "signpost this to the examiner using 'diseourse markers' or a direct statement.
You could say:
As for myself, I guess...
Well, speaking personally here, I can say that / like TV because...
I'm not sure, but personally I can say that watching TV can...
Perhaps I can answer that by looking first at myself. I like TV because...
Perhaps my own reasons can illustrate an answer. TV relaxes me...
In fact [past time reference, eg. just last week'], I...

This could be linked back to the general view with a concluding statement beginning with 'So...". In our example, you could say:
So,
I think other people would generally feel the same way.
probably most people have hobbies for the same reasons as me.
I'm probably typical of most people in this respect.
I guess most people would feel similar to that.
that's probably why people like TV.
