This question style is similar to a multiple answer question in that it allows more than one option to be chosen. Where it differs is that it presents a long list of options. As in the example below it can be used to present a list of equivalent options, e.g. possible investigations. In this example it has been used in conjunction with negative marking. This question is considered to be a way of replacing a traditional short answer question where the student would be required to list all the appropriate investigations.
