Please choose the correct ending to complete the given sentence: Food and Entertaining: [header] How to keep bears away [title] Hide your garbage with bear-proof trash cans. [step] Bears are attracted to food smells, so they will want to dig through your garbage. A bear-proof trash can uses a locking lid to keep bears out of it.

Ending1: This latches tightly and won't close tightly, but some bears can get into the can. [substeps] Put trash in a piece of paper and tape up sticky notes around the edges to mark where bears can't dig through the paper. Ending2: They're also sturdier than other trash cans. [substeps] Another option is a locked shed to hold your garbage cans. Ending3: Make sure it doesn't let in strong odors like gasoline, smoke, or rotten eggs. [substeps] Move the trash cans far away so your bears won't see them. Ending4: Next to it, there should be a chain link door. Make sure it has a padlock locked on the top so bears can't break it.
