Please choose the correct ending to complete the given sentence: Home and Garden: [header] How to build a fire [title] Buy pre-cut firewood to play it safe, if possible. [step] Kindling is material that burns easily when it comes in contact with lit tinder, but is difficult to light its own. Look for small sticks, twigs, and large pieces of bark.

Ending1: Make sure that the items are completely dry. [substeps] Cut large pieces of wood with an axe or knife to create kindling. Ending2: You will need enough firewood for this game. [title] Decide whether you want to include a fence in the game. Ending3: These may have sharp, uneven ends and fall off before the fire starts. [substeps] Note that firewood will be easier to melt, and that you can burn everything, even if you have extras on hand. Ending4: Run your hands through the kindling pile and find the pieces of wood deemed safe for building a fire. Consider which piece of lumber is flat and heavy enough for building a fire, as flat and heavy wood is more flammable than lighter wood.
