premise: ALGOL 68 (short for ALGOrithmic Language 1968) is an imperative computer programming language that was conceived as a successor to the ALGOL 60 programming language, designed with the goal of a much wider scope of application and more rigorously defined syntax and semantics.
hypothesis: It was created in 1968.
reason: Even though it says 1968 we are not sure if that's when it was exactly created or jsut when it was introducted for use.
