We can create a new question type which will support ability to insert placeholders in question text. Something like this:
Most parents are well [26] but some of them aren't very helpful with the problems their sons and daughters have in [27] ...
[26], [27] and etc. will be replaced with textboxes on frontend and it will be possible to define correct answer(s) for each placeholder and set number of points per each answer. If you are interested in it, we can discuss details for this custom development by
email.
