Improved English instructions
Importing questions failed because the list of subquestions in $options->subquestions is a comma-separated string, but get_in_or_equal needs to be handed an array to work properly. It was returning "= ?" even when there were multiple subquestions, which caused only the first one to be turned into a flash card.
