I am wondering if anyone has run into the following issue. I have a question where 3 blanks can be filled with any of the 3 correct answers.
For example, the question is "The three vertical cavities are the [term1], [term2], and [term3].
The correct answers are, abdominal, pelvic, an thoracic, in any order, of course.
If a student writes the same answer twice, for example, "abdominal, abdominal, and pelvic", the quiz will score these 3 answers as the correct answer.
Does anyone know if there is a way to mark a duplicate answer as incorrect?
