Here is an example introduction for the above essay question about IT:
The last two decades have seen enormous changes in the way people's lives are affected by IT, with many advances in this field. However, while these technological advances have brought many benefits to the world, it can be argued that these developments in IT will result in more negative impacts than postive.
As you can see, the first sentence makes sure it refers to the topic (IT) and uses facts about IT taken from the question. Note that these are paraphrased - you must not copy from the rubric!
The second part then clearly sets out the what the essay will be about and confirms the writers opinion (some questions may not ask for your opinion, but this one does).
