3.29 You should understand that mutation is a rare, random change in genetic material that can be inherited
3.30 You should describe the process of evolution by means of natural selection
3.31 You should understand that many mutations are harmful but some are neutral and a few are beneficial
3.33 You should understand that the incidence of mutations can be increased by exposure to ionising radiation (for example gamma rays, X-rays and ultraviolet rays) and some chemical mutagens (for example chemicals in tobacco).

Imagine you work for the Daily Mail’s PR department and have to reply to a number of worried people writing in scared that they will get cancer. You must write in a polite, professional style and assume that the worried reader got a grade E in their Biology O Level exams 25 years ago.
Grade B/A

Grade A/A*
Evaluate the evidence.
Analyse the risk described. If an actual experiment has been conducted, how “reliable”, “valid” and “precise” is the study? If the article quotes a scientist, quickly google his/her name and find out how reliable a source he/she is. What is he/she actually saying and might his/her words have been misrepresented?
