Please choose the correct ending to complete the given sentence: Home and Garden: [header] How to preserve a tree stump [title] Wipe the top and bottom of the stump with a wet cloth. [step] Start by cleaning off any dirt or surface debris on the stump with a cloth. Rub the wood grain in a gentle, circular motion on the top and bottom, where the stump has been cut.

Ending1: [substeps] You will see the stump start to brown some. This happens when sap or coarse matter (including bark) floats to the top. Ending2: You may need to cover the stump with something thick and plastic, like tape, to get an even coverage. [substeps] The stump should appear clean, without any marks, when you are finished. Ending3: [substeps] Do not wipe the bark with the cloth, as this can cause the bark to flake or fall off. [title] Remove any flaking wood or bark on the stump. Ending4: [substeps] Warm up the cleaned rag with five-to 10-second intervals. This will allow moisture to work its way deeper into the stump, and prevent it from drying out too quickly.
