A very good idea for a worksheet, thanks so much for sharing it.
If you want to improve it (I have read in your profile that you like experimenting), here's a piece of advice: I would edit the original document and change the colour of all the key verbs to very light grey, then generate the .pdf and upload it again, so that they won't interfere visually with the choices the student makes. You can also make the font thicker and bigger to make it easier to read after an option has been chosen.
You should also leave some extra space after each verb so that the arrow does not cover the next word.
If you need any help with this, look up my profile to find out how to contact me.
