You should always match it as closely as possible (usually exactly as used in the audio) because the words you have to fill in must be grammatically correct in the sentence. It's basically hearing copy & paste
E.g.
Turtles have sharp claws they can use to scratch you (correct)
Turtles have sharp claw they can use to scratch you (grammatically incorrect)
So from what I remember it was claws, streams, mushrooms.
