Q: Information: - An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs. All computer programs, excluding firmware, require an operating system to function. - IEFBR14 is an IBM mainframe utility program . It runs in all IBM mainframe environments derived from OS / 360 , including z / OS. It is a placeholder whose purpose is to do nothing . As it turned out , over the years , its attempt to do nothing was too concise and would cause problems with related tools , leading to the slight expansion of the program . - z/OS is a 64-bit operating system for IBM mainframes, produced by IBM. It derives from and is the successor to OS/390, which in turn followed a string of MVS versions. Like OS/390, z/OS combines a number of formerly separate, related products, some of which are still optional. z/OS offers the attributes of modern operating systems but also retains much of the functionality originating in the 1960s and each subsequent decade that is still found in daily use (backward compatibility is one of z/OS's central design philosophies). z/OS was first introduced in October 2000. - Multiple Virtual Storage, more commonly called MVS, was the most commonly used operating system on the System/370 and System/390 IBM mainframe computers. It was developed by IBM, but is unrelated to IBM's other mainframe operating systems, e.g., VSE, VM, TPF. - OS/390 is an IBM operating system for the System/390 IBM mainframe computers. - IBM mainframes are large computer systems produced by IBM since 1952. During the 1960s and 1970s, the term mainframe computer was almost synonymous with IBM products due to their marketshare. Current mainframes in IBM's line of business computers are developments of the basic design of the IBM System/360. - Backward compatibility is a property of a system, product, or technology that allows for interoperability with an older legacy system, or with input designed for such a system, especially in telecommunications and computing. Backward compatibility is sometimes abbreviated to BC, or called downward compatibility. Modifying a system in a way that does not allow backward compatibility is sometimes called "breaking" backward compatibility. A complementary concept is forward compatibility, which is a design philosophy, usually based on open standards, that strives for methods that will continue to work with newer and future products. Design that is forward-compatible usually has a roadmap for compatibility with future standards and products. Given the paragraphs above, decide what entity has the relation 'part of' with 'mainframe computer'.
A: iefbr14

Question: Information: - Bloom County is an American comic strip by Berkeley Breathed which originally ran from December 8, 1980, until August 6, 1989. It examined events in politics and culture through the viewpoint of a fanciful small town in Middle America, where children often have adult personalities and vocabularies and where animals can talk. It originated from a comic strip known as "The Academia Waltz", which Breathed produced for the student newspaper, "The Daily Texan", while attending the University of Texas. - Bill the Cat, or Bill D. Cat, is a fictional cat appearing in the works of cartoonist Berkeley Breathed, beginning with the comic strip "Bloom County" in the 1980s and continuing in "Outland" and "Opus" in the following decades. Bill also appeared in some of Breathed's illustrated children's books, including "A Wish for Wings That Work", which was also made into an animated Christmas television special, and also on greeting cards and other sundry merchandise. The cat's most frequent spoken sentiments are "Ack!" and "Thppt!", unlike most other animals (and children) in Breathed's work, who not only can speak English, but have advanced vocabularies. The former is a result of his regularly choking on hairballs, the latter sound an approximation of the "raspberry". - Guy Berkeley "Berke" Breathed (; born June 21, 1957) is an American cartoonist, children's book author/illustrator, director and screenwriter, best known for "Bloom County", a 1980s cartoon-comic strip and more recent Internet cartoons that reflect sociopolitical issues as understood by fanciful characters (e.g., Bill the Cat and Opus the Penguin) and through humorous analogies. "Bloom County" earned Breathed the Pulitzer Prize for Editorial Cartooning in 1987. - Opus the Penguin (Opus T. Penguin) is a fictional character created by artist Berkeley Breathed. Breathed has described him as an "existentialist penguin" and the favorite of his many characters. - Goodnight Opus ( ISBN 978 - 0 - 316 - 10853 - 9 ) is a 1993 children 's book by Berkeley Breathed featuring Opus the Penguin . Goodnight Opus is a take - off of the popular Goodnight Moon children 's book ; this book actually begins with Opus being read Goodnight Moon by a maternal nanny figure while he sits in bed in his pink pajamas . After the nanny falls asleep while reading , Opus goes on his own journey to say goodnight to all sorts of fanciful beings and animals . The entire journey is an ode to imagination and to going beyond the last pages of a book . Because the book encourages readers to think radically , it has '' been banned in seventeen countries with early bedtimes '' , according to Breathed 's website . The book ultimately served as a foreshadowing of Opus 's fate ; in the character 's final story - arc in the Opus comic strip , he is encouraged by the ghost of Elvis and Breathed himself to choose someplace where he can spend eternity in peace . The final strip finds that Opus has chosen to spend eternity sleeping in the bed on the final page of Goodnight Moon . - Penguins (order Sphenisciformes, family Spheniscidae) are a group of aquatic, flightless birds. They live almost exclusively in the Southern Hemisphere, with only one species, the Galapagos penguin, found north of the equator. Highly adapted for life in the water, penguins have countershaded dark and white plumage, and their wings have evolved into flippers. Most penguins feed on krill, fish, squid and other forms of sealife caught while swimming underwater. They spend about half of their lives on land and half in the oceans. Given the paragraphs above, decide what entity has the relation 'series' with 'bloom county'.
