In Sleeping in a noisy environment, quite a lot of the answers are almost duplicates or very slight variations of the theme of ear plugs.
How do we handle such cases? Should we downvote the similar answers, and if so, which to choose as a keeper? If downvoting, should one comment? Which other options do we have?
Edit: In addition, how to handle when multiple answers are quite similar? What options do we have to consolidate answers?
