Q: Information:  - Qingdao (also spelled Tsingtao) is a city in eastern Shandong Province on the east coast of China. It is the largest city in its province. Administered at the sub-provincial level, Qingdao has jurisdiction over six districts and four county-level cities. Qingdao had a population of 9,046,200 with an urban population of 6,188,100. Lying across the Shandong Peninsula and looking out to the Yellow Sea, it borders Yantai to the northeast, Weifang to the west and Rizhao to the southwest. "Qng" in Chinese means "cyan" or "greenish-blue", while "do" means "island".  - Liaoning is a province of China, located in the northeast of the country. The modern province was established in 1907 as Fengtian or Fengtien province and the name was changed to Liaoning in 1929. It was also known as Mukden province at the time, for the Manchu pronunciation of Shengjing, the former name of the provincial capital Shenyang. Under the Japanese-puppet Manchukuo regime, the province reverted to its 1907 name but the name Liaoning was restored in 1945 and again in 1954.  - Manchuria is a modern name, first created by Japanese, given to a large geographic region in Northeast Asia. Depending on the context, Manchuria can either refer to a region that falls entirely within the People's Republic of China, or a larger region divided between China and Russia. The region that falls entirely within modern China is now usually referred to as Northeast China in China, although "Manchuria" is widely used outside of China to denote the geographical and historical region. This region is the traditional homeland of the Xianbei, Khitan, and Jurchen (later called Manchu) peoples, who built several states historically, although no term for "Manchuria" exists in the Manchu language, which originally referred to the area as the "Three Eastern Provinces".  - Early life. Toshiro Mifune was born on 1 April 1920 in Qingdao, Shandong, China, to Japanese parents. His parents were Methodist missionaries working there. Mifune grew up with his parents and two younger siblings in Dalian, Liaoning, China, and, from 4 to 19 years of age, in Manchuria. Mifune was a Christian born to Missionary parents.  - High and Low (  Tengoku to Jigoku , literally `` Heaven and Hell '' ) is a 1963 police procedural crime drama film directed by Akira Kurosawa , starring Toshiro Mifune , Tatsuya Nakadai and Kyko Kagawa . The film is loosely based on King 's Ransom ( 1959 ) , by Ed McBain .    After reading the paragraphs above, we are interested in knowing the entity with which 'high and low ' exhibits the relationship of 'original language of work'. Find the answer from the choices below.  Choices: - chinese  - japanese
A: japanese


Q: Information:  - 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.  - In mathematics, a structure on a set is an additional mathematical object that, in some manner, attaches (or relates) to that set to endow it with some additional meaning or significance.  - In mathematics, a topological group is a group "G" together with a topology on "G" such that the group's binary operation and the group's inverse function are continuous functions with respect to the topology. A topological group is a mathematical object with both an algebraic structure and a topological structure. Thus, one may perform algebraic operations, because of the group structure, and one may talk about continuous functions, because of the topology.  - In category theory , a branch of mathematics , group objects are certain generalizations of groups which are built on more complicated structures than sets . A typical example of a group object is a topological group , a group whose underlying set is a topological space such that the group operations are continuous .  - A definition is a statement of the meaning of a term (a word, phrase, or other set of symbols). Definitions can be classified into two large categories, intensional definitions (which try to give the essence of a term) and extensional definitions (which proceed by listing the objects that a term describes). Another important category of definitions is the class of ostensive definitions, which convey the meaning of a term by pointing out examples. A term may have many different senses and multiple meanings, and thus require multiple definitions.  - Mathematics (from Greek  "máthma", 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.  - Quantity is a property that can exist as a magnitude or multitude. Quantities can be compared in terms of "more", "less", or "equal", or by assigning a numerical value in terms of a unit of measurement. Quantity is among the basic classes of things along with quality, substance, change, and relation. Some quantities are such by their inner nature (as number), while others are functioning as states (properties, dimensions, attributes) of things such as heavy and light, long and short, broad and narrow, small and great, or much and little. A small quantity is sometimes referred to as a quantulum.  - Space is the boundless three-dimensional extent in which objects and events have relative position and direction. Physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework.    After reading the paragraphs above, we are interested in knowing the entity with which 'group object' exhibits the relationship of 'subclass of'. Find the answer from the choices below.  Choices: - algebraic structure  - binary operation  - category  - category theory  - definition  - direction  - essence  - greek  - learning  - magnitude  - mathematical object  - mathematical structure  - mathematics  - number  - object  - phrase  - position  - property  - quantity  - relation  - space  - statement  - structure  - study  - term  - time  - topology  - unit of measurement  - value
