Please choose the correct ending to complete the given sentence: Computers and Electronics: [header] How to do some basic club dance moves [title] Bounce to the beat. [step] If you're not sure what to do on the dance floor, just bounce to the beat. You do this by bending your knees slightly and then standing back up to the beat.

Ending1: [substeps] Take two steps forward and three steps back and forth. Keep your back straight and slightly lifted back. Ending2: It's totally normal! [title] Pick a partner to dance to as you dance. [step] It doesn't have to be a well-timed dance, of course-one-partner dancing is great. Ending3: Continue to bounce your weight up and down to the beat, as you stand behind a chair, your heels over the sides of the chair. [substeps] To start your dance, stand slightly behind or to the left of the chair. Ending4: This can be a very small, fast move that makes you look like you're just bobbing along to the music, or a much larger, pronounced motion where you're exaggerating the bends and the pauses. Try shifting your body from side to side so you don't look like a buoy in the water.
