In a multiple-choice question, the respondent is shown the question and the answer choices, from which they must select either one (radio buttons, Task 1) or several (checkboxes, Task 2 and Task 3). The number of choices is determined by the task creator. In the case of checkboxes, it is also possible to specify the maximum number of allowed choices. When the maximum number of choices is made, a corresponding message is displayed to the solver (Task 3).
For the choices, the task creator can also specify whether they are always displayed in the same order or if a new order is generated each time the task is opened (Task 2 and Task 3).
