Text: i couldn't remember in Tigon had purchased GTE's phone mail services or if GTE had purchased Tigon i knew there was some type of a tie in there i remember reading in the paper a few months back but
Entailment: I do not recall exactly but I remember reading in the news several months ago about Tigon and GTE and how there was a tie of some sort for the buyout.
Contradiction: I remember clearly seeing on television that there was no tie between GTE and Tigon and that Tigon had bought GTE's phone services.
