Multiple choice type

If some items have more than two options and each item has only one good option, you have to choose the multiple choice type. In this case you also have to give the correction key. The values in this field have to be comma separated and contains no spaces. To help you input the correction key, its length is displayed. If the corrction key is in the selected range and the appropriate box was checked in the first step, then the key is already into this field.
