How can I write a strong introduction to an unseen text exam question?

Beginning to write in an English exam is difficult, especially when it is an exam question revolving around a text you have never encountered with before. There is, however, five features which you can include in your introduction to help the examiner recognise your ability to understand the text and the author's motives. The helpful and easy to remember acronym, PAGCT can ensure a strong introduction. - Purpose: what is the author's motive in writing this text? - Audience: who is this text intended for? - Genre: what kind of text is it? - Context: when was this written? What was happening when it was written? - and Tone: what is the authors' tone? How does this impact the features above?
