Input: Read this: His next directorial feature was the Raiders prequel Indiana Jones and the Temple of Doom. Teaming up once again with Lucas and Ford, the film was plagued with uncertainty for the material and script. This film and the Spielberg-produced Gremlins led to the creation of the PG-13 rating due to the high level of violence in films targeted at younger audiences. In spite of this, Temple of Doom is rated PG by the MPAA, even though it is the darkest and, possibly, most violent Indy film. Nonetheless, the film was still a huge blockbuster hit in 1984. It was on this project that Spielberg also met his future wife, actress Kate Capshaw.
Question: Which is the least violent Indiana Jones movie?

Output: unanswerable


Input: Read this: Kanye West began his early production career in the mid-1990s, making beats primarily for burgeoning local artists, eventually developing a style that involved speeding up vocal samples from classic soul records. His first official production credits came at the age of nineteen when he produced eight tracks on Down to Earth, the 1996 debut album of a Chicago rapper named Grav. For a time, West acted as a ghost producer for Deric "D-Dot" Angelettie. Because of his association with D-Dot, West wasn't able to release a solo album, so he formed and became a member and producer of the Go-Getters, a late-1990s Chicago rap group composed of him, GLC, Timmy G, Really Doe, and Arrowstar. His group was managed by John "Monopoly" Johnson, Don Crowley, and Happy Lewis under the management firm Hustle Period. After attending a series of promotional photo shoots and making some radio appearances, The Go-Getters released their first and only studio album World Record Holders in 1999. The album featured other Chicago-based rappers such as Rhymefest, Mikkey Halsted, Miss Criss, and Shayla G. Meanwhile, the production was handled by West, Arrowstar, Boogz, and Brian "All Day" Miller.
Question: What music group did Kanye join when he couldn't release his solo album?

Input: Read this: Today, computer security comprises mainly "preventive" measures, like firewalls or an exit procedure. A firewall can be defined as a way of filtering network data between a host or a network and another network, such as the Internet, and can be implemented as software running on the machine, hooking into the network stack (or, in the case of most UNIX-based operating systems such as Linux, built into the operating system kernel) to provide real time filtering and blocking. Another implementation is a so-called physical firewall which consists of a separate machine filtering network traffic. Firewalls are common amongst machines that are permanently connected to the Internet.
Question: What is defined as a way of filtering network data between a host or network and another network?
