Choose the right phrase to complete the teenager's midnight snack diary.

I carefully opened the fridge, but I completely forgot to _____ the kitchen security alarm. Now the whole house is awake and my secret pizza is ruined!

The correct answer is turn off.

We use turn off to mean stopping a machine, light, or electronic device from working (like deactivating an alarm).

Turn down means to lower the volume or temperature, which wouldn't stop the security alarm from triggering!
