Complete the anxious roommate's text message by choosing the correct phrasal verb.

Hey! I'm already on the bus, but I can't remember if I touched the stove this morning. Could you please check the kitchen and _____ the oven if I left it running?

The correct answer is turn off.

The phrasal verb "turn off" means to stop a machine, appliance, or light from working by using a switch or button.

Here is why the other options are incorrect:

• Turn on means to start the machine (which would make the roommate even more anxious!).

• Turn up means to increase the power, heat, or volume.

• Turn down means to decrease the heat or volume, but it doesn't stop the machine entirely.
