Suppose The Beatles were an English rock band formed in Liverpool in 1960. With a line-up comprising John Lennon, Paul McCartney, George Harrison, and Ringo Starr, they are commonly regarded as the most influential band of all time. Their sound was rooted in skiffle, beat and 1950s rock and roll, but they later experimented with genres ranging from pop ballads to psychedelic rock.
Can we infer that "The Beatles disbanded in the 1970s"? Yes, no, or maybe?
