Are quizzes that are entirely fill-in-the-blank permissible in Humanities, specifically under English --> Vocabulary?

Yes, we have a number of such quizzes. But they can be hard to write, because we do enforce the rule that each FITB question should have only one unambiguous answer (apart from minor spelling variations, e.g. US vs UK). This can be hard in vocabulary quizzes where there are so many synonyms!

Thanks, CD. It should work okay for vocabulary 'theme' I had in mind (i.e. not too many multiple correct answers)
