Text: i certainly didn't mark off anything to get this one i can't i can't imagine and the switchboard's been down for several days and the last time i called it before it went down i had this topic and i didn't feel like talking about it so i hung up and i guess they they keep you on the same topic until you actually talk to somebody about it
Entailment: They don't switch topics until you converse with someone about it.
Contradiction: They switch topics even if you don't converse with someone about it.
