On question 1 remember to write an opening statement and a short conclusion this will take you to the top band for the most marks. Use the three bullet points for your paragraphs and make at least 3 points or more (preferably 5) in each paragraph. You also need to be aware of the style of writing and the points that you infer in the last bullet point must be relevant.
Question 2 is about the powerful word/phrases and the key thing to remember here is to choose phrases with imagery and connotations. Use PME - Point, Meaning, Effect as a base to write the answer. You can also write a general opening sentence to introduce the phrases you have picked out.
Question 3 in my opinion is the easiest purely because it is a locate and retrieve question. The summary to this question needs to be informative but also short and concise. Try not to make things up or use the bullet points you haven't written down prior to the summary. Every point needs to be relevant and should not be repeated. There is no need for a opening or conclusion but make sure it is written in your own words.
Hope That Helps!
