On other on line platforms they have the availability to check "Contains" box on fill in the blank.
This allows the instructor to look for one or a few words without having the student miss the questions.
Who is the President of United States?
Correct answer: Obama
Not Barack Obama
Not Barack H. Obama
Not Barack H Obama
With the "Contain" box check all the above answers would be correct along with such answers a "President Obama"
Or any other works as long as Obama is in the answer.
