Multiple choice questions
Multiple choice questions are perhaps the easiest to complete, you simply put a cross in a box. However, the questions often have two answers that could, at first glance, be correct. Don’t make the mistake of reading the first answer and thinking this is correct without checking all the others.
If it says 'Tick one box', you must tick one box. If you leave it blank or tick two or more boxes you will get zero marks. These multiple choice questions will not start with command words like ‘describe’ or ‘explain’. They will be written in the form of a question like ‘What…?’ or ‘Why…?’.
There will be more multiple choice questions on the Foundation paper.

Sample question 4 - Higher
Question
FOP is a disorder that causes soft tissue in the body to turn to bone. It is caused by a dominant allele. People who have this condition are often infertile. Natural selection predicts that the number of children born with the condition will go down.
Which explantion can explain why the number of people with FOP is staying constant? [1 mark]
Tick one box.
| A | The allele is being produced regularly by mutation. | |
| B | Dominant alleles can remain hidden for generations. | |
| C | The allele may increase the rate of meiosis. | |
| D | The allele has no effect on a person's phenotype. |
