FACTS AND OPINIONS
Persuasive writing relies on the use of facts and opinions to support the points its writer makes. But readers are often less than able to recognise how trustworthy these facts and opinions are.
It is important that you can separate fact from opinion and also recognise that most facts used in persuasive writing are highly selective (i.e. they do not tell the whole story - just the part the writer wants to show) and that most opinions are either presented as if they are facts or are made to seem entirely trustworthy.
