All these answers should be bullet pointed. For examiners, in the actual mark scheme, it shows answers in a bullet format. This makes it easy for the examiner to see. These are the hardest marks to get in my experience. I normally advise these questions to be answered last as they reward you with the least amount of marks. There are two marks awarded for each complete pair. E.g. 2 marker requires one pair, 6 marker requires 3 pairs. Each pair consists of "one way" and an explanation. In essence, point explain. Most students are only awarded half marks because they do not correctly present the first part. Let's look at the example below. Note how concise the examiner wants your answers. Students tend to spend far too long on these answers. Keep them short, sweet and to the point. Leaving them until last stops you from waffling and ensures this.
