Question

Which step must happen before starting the timer?

a Check the battery compartment.
b Attach the cord.
c Set the desired time.

Answer 1

If the timers numbers are displayed on the screen then you don't have to replace the batteries so, the answer is C.

Answer 2

You need to set the desired time because some timers don't have cords and you don't have to check the battery compartment before starting the timer. So the answer is B. Hope that help you.
