A few ideas for expanding the possibilities of Fill in the Blanks.
This question is very good for completing continuous texts or for teaching grammar in languages. However, its application would be much wider if
1) a better text editor was integrated in the "line of text" part - inserting basic symbols (subscripts, Greek alphabet characters, mathematical symbols) - not everyone has the technical ability and knows LaTeX, the ability to insert an image as a "character" (popular are texts in which some words are replaced by small images and children complete them), the ability to insert a "table"
2) If the parts of the "line of text" were randomly shuffled each time they are loaded
Thanks
