Answer:
Add the broadcast jump! code to the end of Scratch Cat's code.
Step-by-step explanation:
If we broadcast the jump! code, then the Gobo will listen, and he will start jumping up and down. It looks like that he is not getting what Scratch Cat is saying, and if the message of Scratch Cat is broadcasted then Gobo will listen to what Scratch Cat is telling. Hence, the above option is the correct option.
