Q: Information: - Stronger Than Ever is the fourth studio album by the German heavy metal band Grave Digger . However , they changed their name to just '' Digger '' for this release . Retrospect Records , a little - known record label , very briefly issued a re-release of the album on CD in 2005 . The CD was released with presumably no involvement from the band and is considered a bootleg . The CD is no longer available and the only official versions of the album that were released by the band are the vinyl and cassette versions . To this day it remains the only album in Grave Digger 's catalog to not receive an official CD release . '' Shadows Of The Past '' borrows two lyrical lines from '' Yesterday '' , a song released on Heavy Metal Breakdown , Grave Digger 's debut album . - Albums of recorded music were developed in the early 20th century, first as books of individual 78rpm records, then from 1948 as vinyl LP records played at rpm. Vinyl LPs are still issued, though in the 21st century album sales have mostly focused on compact disc (CD) and MP3 formats. The audio cassette was a format used from the late 1970s through to the 1990s alongside vinyl. - Noise Records is a German heavy metal record label founded in 1983 by German music industry personality Karl-Ulrich Walterbach as an expansion of his company Modern Music Records. Noise Records specialized in thrash and melodic speed metal. It was sold to the Sanctuary Records Group in 2001 and ceased any activity in 2007 due to the bankruptcy of Sanctuary. The Noise catalogue was consequently acquired by Universal Music Group later on. In April 2016, BMG Rights Management, which had acquired Sanctuary Records in 2013, announced that it would revive the Noise Records label. - Heavy Metal Breakdown is the debut album by the German heavy metal band Grave Digger which was released in October 1984 by Noise Records. What object entity has the relation of 'record label' with the subject 'stronger than ever '? Choices: - album - label - noise records - record - record label - sanctuary records group

Q: Information: - Given a category C and a morphism f \ colon X \ to Y in C , the image of f is a monomorphism h \ colon I \ to Y satisfying the following universal property : There exists a morphism g \ colon X \ to I such that f = hg . For any object Z with a morphism k \ colon X \ to Z and a monomorphism l \ colon Z \ to Y such that f = lk , there exists a unique morphism m \ colon I \ to Z such that h = lm. Remarks : such a factorization does not necessarily exist g is unique by definition of monic ( = left invertible , abstraction of injectivity ) m is monic . h = lm already implies that m is unique . k = mg The image of f is often denoted by im f or Im ( f ) . One can show that a morphism f is epic if and only if f = im f. - In the context of abstract algebra or universal algebra, a monomorphism is an injective homomorphism. A monomorphism from "X" to "Y" is often denoted with the notation formula_1. - In algebra, a homomorphism is a structure-preserving map between two algebraic structures of the same type (such as two groups, two rings, or two vector spaces). The word "homomorphism" comes from the ancient Greek language: " (homos)" meaning "same" and " (morphe)" meaning "form" or "shape". - Category theory formalizes mathematical structure and its concepts in terms of a collection of "objects" and of "arrows" (also called morphisms). A category has two basic properties: the ability to compose the arrows associatively and the existence of an identity arrow for each object. The language of category theory has been used to formalize concepts of other high-level abstractions such as sets, rings, and groups. - Mathematics (from Greek "mathma", knowledge, study, learning) is the study of topics such as quantity (numbers), structure, space, and change. There is a range of views among mathematicians and philosophers as to the exact scope and definition of mathematics. - In various branches of mathematics, a useful construction is often viewed as the most efficient solution to a certain problem. The definition of a universal property uses the language of category theory to make this notion precise and to study it abstractly. - In algebra, which is a broad division of mathematics, abstract algebra (occasionally called modern algebra) is the study of algebraic structures. Algebraic structures include groups, rings, fields, modules, vector spaces, lattices, and algebras. The term "abstract algebra" was coined in the early 20th century to distinguish this area of study from the other parts of algebra. - Universal algebra (sometimes called general algebra) is the field of mathematics that studies algebraic structures themselves, not examples ("models") of algebraic structures. For instance, rather than take particular groups as the object of study, in universal algebra one takes "the theory of groups" as an object of study. What object entity has the relation of 'part of' with the subject 'image '? Choices: - 20th century - abstract algebra - algebra - category theory - division - learning - mathematics - theory - universal algebra - word
