Please choose the correct ending to complete the given sentence: Holidays and Traditions: [header] How to hang lights on a christmas tree [title] Plug the lights in to make sure that each bulb works. [step] If a few don't, try tightening them-they may not be broken after all. Once you're confident they work, unravel them.

Ending1: [substeps] You can use a gelatin dropper to remove any stuck-on bits. After disconnecting one bulb from each carbon pod, twist the carbon pod's bottom back end just enough to loosen it from the supporting wires. Ending2: This way you don't spend minutes unraveling what you don't use. [substeps] Spend a couple of minutes tinkering with them, and then if they still don't work, throw them out. Ending3: When you have tightened the lights, pull the light tube out of the wall. Repeat this for all the lights on the tree. Ending4: Leave a small amount of extra string at the bottom to work with. The last thing you want is for your lights to slide off during light traffic or hot flashes-you never know when your lights might come in handy next.
