• The Multiple Choice format is more explicit and visual. This makes it a more appropriate choice for presenting tricky or complicated answer options which areintended to get the student to pause and think.

This response type allows to add more than one answer. Use `additional_answer` tag to add more answers.
|
||||
|
||||
You can add `regexp` to value of `type` attribute, for example: `type="ci regexp"` or `type="regexp"` or `type="regexp cs"`.
|
||||
In this case, any answer and hint will be treated as regular expressions.
|
||||
Regular expression has to match whole answer, for answer to be correct.
|
||||
Student answers "foobar", "o foo" or " ==foo==", will be correct if teacher has set answer=".*foo.*" with type="regexp".
