premise: Fleetwood Mac are a British-American rock band, formed in London in 1967. The band have sold more than 100 million records worldwide, making them one of the world's best-selling bands of all time. In 1998, selected members of Fleetwood Mac were inducted into the Rock and Roll Hall of Fame, and received the Brit Award for Outstanding Contribution to Music.
hypothesis: When Fleetwood Mac formed in 1967, they were immediately inducted into the Rock and Roll Hall of Fame the same year for ovewhelming awesomeness.
reason: The context states that only select members were inducted to the Hall of Fame in 1998. I really don't know why the AI didn't get this one. Something about the order of words and throwing in the random "overwhelming awesomeness" must have stumped it.
