Matching exercises in Runestone require users to drag options from left to right and be dropped on their match. But it also allows options to be dragged up and down, which gives the impression that you can just align them with their match. However, that does not work.
Suggestion is to add a clarifying statement to the first (or all) matching exercises saying: "Drag and drop the options on the left to their matching statement on the right."
