Information: - Sea snail is a common name for snails that normally live in saltwater, in other words marine gastropods. The taxonomic class Gastropoda also includes snails that live in other habitats, such as land snails and freshwater snails. Many species of sea snails are edible and exploited as food sources by humans. - Volvatellidae is a taxonomic family of sea snails , marine gastropod mollusks in the superfamily Oxynooidea . This family has no subfamilies . - Oxynooidea is a superfamily of small sea snails, bubble snails and bivalved gastropods, marine gastropod mollusks within the clade Sacoglossa. - Sacoglossa, commonly known as the sacoglossans or the "sap-sucking sea slugs", are a clade of small sea slugs and sea snails, marine gastropod mollusks that belong to the clade Heterobranchia. Sacoglossans live by ingesting the cellular contents of algae, hence the adjective "sap-sucking". What object entity has the relation of 'parent taxon' with the subject 'volvatellidae'? Choices: - gastropoda - sacoglossa
sacoglossa
Question: Information: - TeX (or , see below) is a typesetting system (or "formatting system") designed and mostly written by Donald Knuth and released in 1978. Together with the Metafont language for font description and the Computer Modern family of typefaces, TeX was designed with two main goals in mind: to allow anybody to produce high-quality books using minimal effort, and to provide a system that would give exactly the same results on all computers, at any point in time. TeX is free software, which has made it more accessible to a wider range of users. - GNU Emacs is the most popular and most ported Emacs text editor. It was created by GNU Project founder Richard Stallman. In common with other varieties of Emacs, GNU Emacs is extensible using a Turing complete programming language. GNU Emacs has been called "the most powerful text editor available today." With proper support from the underlying system, GNU Emacs is able to display files in multiple character sets, and has been able to simultaneously display most human languages since at least 1999. Throughout its history, GNU Emacs has been a central component of the GNU project, and a flagship of the free software movement. GNU Emacs is sometimes abbreviated as GNUMACS, especially to differentiate it from other EMACS variants. The tag line for GNU Emacs is "the extensible self-documenting text editor". - Richard Matthew Stallman (born March 16, 1953), often known by his initials, rms, is an American software freedom activist and programmer. He campaigns for software to be distributed in a manner such that its users receive the freedoms to use, study, distribute and modify that software. Software that ensures these freedoms is termed free software. Stallman launched the GNU Project, founded the Free Software Foundation, developed the GNU Compiler Collection and GNU Emacs, and wrote the GNU General Public License. - The GNU Project is a free software, mass collaboration project, announced on September 27, 1983, by Richard Stallman at MIT. Its aim is to give computer users freedom and control in their use of their computers and computing devices, by collaboratively developing and providing software that is based on the following freedom rights: users are free to run the software, share it (copy, distribute), study it and modify it. GNU software guarantees these freedom-rights legally (via its license), and is therefore free software; the use of the word "free" always being taken to refer to freedom. - GNU TeXmacs is a free scientific word processor and typesetting component of the GNU Project . It was inspired by TeX and GNU Emacs , though it shares no code with those programs . TeXmacs does use TeX fonts . It is written and maintained by Joris van der Hoeven . The program produces structured documents with a WYSIWYW user interface . New document styles can be created by the user . The editor provides high - quality typesetting algorithms and TeX fonts for publishing professional looking documents . - GNU is an operating system and an extensive collection of computer software. GNU is composed wholly of free software, most of which is licensed under the GNU Project's own GPL. - Free software, freedom-respecting software, or software libre is computer software distributed under terms that allow the software users to run the software for any purpose as well as to study, change, and distribute the software and any adapted versions. Free software is a matter of liberty, not price: users, individually or collectively, are free to do what they want with it, including the freedom to redistribute the software free of charge, or to sell it, or charge for related services such as support or warranty for profit. What object entity has the relation of 'license' with the subject 'gnu texmacs'? Choices: - free software - gnu general public license
Answer:
gnu general public license
