This question type can be tricky if there is more than a one-word answer (which may have spelling problems!), or variations on the answer. You can avoid this problem by:
using wildcards (*) – see information below Steps
putting in the question stem (Question text) a proviso such as 'Please separate words with a comma' (if a two-word answer) or other similar guidance
anticipating the variations and adding those to the answers with 100% as the correct grade for each variation
It would be a good idea to test this question on several users before you try it with students in the real situation, especially if it is assessed.

Using wildcards
You can use the asterisk character (*) as a wildcard to match any series of characters. For example, use:
ran*ing
to match any word or phrase starting with ran and ending with ing.
If you really do want to match an asterisk then use a backslash like this:
\*
If you want one question with the two answers fuel and oxygen, you ought to be able to limit
the number of variants by writing:
fuel*oxygen
This would accept "fuel oxygen", "fuel, oxygen", "fuel; oxygen", "fuel and oxygen", "fuel & oxygen" "fuel oxygen", "fuel und oxygen" "fuel&&oxygen". It would even accept "fuel or oxygen", "fuel but not oxygen" "fuel|oxygen" .
Example
Here are some answers and scores for a question "What does a rocket burn?"
oxygen*fuel
with a score 100%
*fuel*
with a score 50%
*oxygen*
with a score 50%
*air*
with a score 40%
*
with a score of 0%
The order of the answers is important. The answers are evaluated from 1st to last. When a match is found the process stops. If no match is found, the question is scored wrong and the general response is used. It is a good practice to put a wildcard as
the last answer so the evaluation process knows what to do when nothing above it matches.
If any answer is the right answer (eg a non-graded open-ended quiz), you could have as the only answer * (worth 100%). This means all answers are acceptable. Make the question worth 0, and if you make the quiz non-graded (i.e. worth 0) it will not appear
in the Gradebook.
