Notice how some words are impossible to change, or if we did change them they would become inaccurate. For example, we could change computers to 'electronic devices', or 'laptops' perhaps but these words do not have the exact same meaning.
They are very 'loose' synonyms and if you use words like these you will lose marks as the meaning of your sentence will not be exactly the same. So always use exactly matching synonyms (direct synonyms), or simply use the same word.
If you cannot find an exact synonym then you can try changing the order of the words instead. This will show a good control of grammar and it may also mean you have to use a different form of the word which again will impress the examiner.
In this case, we changed computer ownership to people that own computers. Although the words are the same the grammar is not, which should positively affect your band score.
Essentially, that is all you need to do in your introduction. Simply restate the question statement in your own words as accurately as possible. The more you practice this the easier it will become.
Next, we will look at how to write your over view paragraph using the key features you identified in step one when you analysed the question.
