Given the question: Information: - Animals are multicellular, eukaryotic organisms of the kingdom Animalia (also called Metazoa). The animal kingdom emerged as a basal clade within Apoikozoa as a sister of the choanoflagellates. Sponges are the most basal clade of animals. Animals are motile, meaning they can move spontaneously and independently at some point in their lives. Their body plan eventually becomes fixed as they develop, although some undergo a process of metamorphosis later in their lives. All animals are heterotrophs: they must ingest other organisms or their products for sustenance. - Modern humans ("Homo sapiens", primarily ssp. "Homo sapiens sapiens") are the only extant members of Hominina tribe (or human tribe), a branch of the tribe Hominini belonging to the family of great apes. They are characterized by erect posture and bipedal locomotion; manual dexterity and increased tool use, compared to other animals; and a general trend toward larger, more complex brains and societies. - The Hominini is a taxonomical tribe of the subfamily Homininae; it comprises three subtribes: Hominina, with its one genus "Homo"; Australopithecina, comprising at least three extinct genera (see inset at bottom right); and Panina, with its one genus "Pan", the chimpanzees (see the evolutionary tree below). Members of the human clade, that is, the Hominina, including "Homo" and those species of the australopithecines that arose "after" the split from the chimpanzees, are called homininans. Not all homininans are directly related to the emergence of early "Homo". A modern cladogram is given by - Thought can refer to the ideas or arrangements of ideas that result from thinking , the act of producing thoughts , or the process of producing thoughts . Although thought is a fundamental human activity familiar to everyone , there is no generally accepted agreement as to what thought is or how it is created . Thoughts may or may not arise in the mind from the product of subconscious brain processing . Because thought underlies many human actions and interactions , understanding its physical and metaphysical origins , processes , and effects has been a longstanding goal of many academic disciplines including psychology , neuroscience , philosophy , artificial intelligence , biology , sociology and cognitive science . Thinking allows humans to make sense of , interpret , represent or model the world they experience , and to make predictions about that world . It is therefore helpful to an organism with needs , objectives , and desires as it makes plans or otherwise attempts to accomplish those goals . - A tribe is viewed, developmentally or historically, as a social group existing before the development of, or outside, states. A tribe is a group of distinct people, dependent on their land for their livelihood, who are largely self-sufficient, and not integrated into the national society. It is perhaps the term most readily understood and used by the general public. Stephen Corry, director of Survival International, an organisation dedicated to indigenous rights, defines tribal people as those who "...have followed ways of life for many generations that are largely self-sufficient, and are clearly different from the mainstream and dominant society." This definition, however, would not apply in countries in the Middle East such as Iraq, where the entire population is a member of one tribe or another, and tribalism itself is dominant and mainstream. - The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. The brain is located in the head, usually close to the sensory organs for senses such as vision. The brain is the most complex organ in a vertebrate's body. In a human, the cerebral cortex contains approximately 1533 billion neurons, each connected by synapses to several thousand other neurons. These neurons communicate with one another by means of long protoplasmic fibers called axons, which carry trains of signal pulses called action potentials to distant parts of the brain or body targeting specific recipient cells. - A mental representation (or cognitive representation), in philosophy of mind, cognitive psychology, neuroscience, and cognitive science, is a hypothetical internal cognitive symbol that represents external reality, or else a mental process that makes use of such a symbol: "a formal system for making explicit certain entities or types of information, together with a specification of how the system does this." - A tool is any physical item that can be used to achieve a goal, especially if the item is not consumed in the process. Tool use by humans dates back millions of years, and other animals are also known to employ simple tools. - Homo is the genus that comprises the species "Homo sapiens", which includes modern humans, as well as several extinct species classified as ancestral to or closely related to modern humans, most notably "Homo erectus". The genus is between 2 and 3 million years old, taken to emerge with the appearance of "Homo habilis". It is derived from the genus "Australopithecus", which itself had previously split from the lineage of "Pan", the chimpanzees. Taxonomically, "Homo" is the only genus assigned to the subtribe Hominina which, with the subtribes Australopithecina and Panina, comprise the tribe Hominini (see evolutionary tree below). All species of the genus "Homo" plus those species of the australopithecines that arose "after" the split from "Pan" are called hominins. - In philosophy, ideas are usually construed as mental representational images of some object. Ideas can also be abstract concepts that do not present as mental images. Many philosophers have considered ideas to be a fundamental ontological category of being. The capacity to create and understand the meaning of ideas is considered to be an essential and defining feature of human beings. In a popular sense, an idea arises in a reflexive, spontaneous manner, even without thinking or serious reflection, for example, when we talk about the "idea" of a person or a place. A new or original idea can often lead to innovation. Given the information above, choose from the list below the object entity that exhibits the relation 'subclass of' with the subject 'thought'. Choices: - action - animal - brain - definition - director - general - homo - homo erectus - homo sapiens - human - life - lineage - mental process - people - point - population - process - public - rights - signal - society - term - tool - tree - tribe
The answer is:
mental process
