問題文

The park settles two more practices for its wardens. The first bears on the list of wireless names a warden picks from when he is away from the site, and not at all on whether his handset announces its own presence to whatever machines happen to be close by. The second bites only on wireless names the handset has already joined at least once, and does nothing whatever about names it has never met. Which pairing names the two practices?
