Extract the answer to the question from the following context. Question: A limb that is not being used is also known as a? Context: A wrestler may voluntarily submit by verbally informing the referee (usually used in moves such as the Mexican Surfboard, where all four limbs are incapacitated, making tapping impossible). Also, since Ken Shamrock (a legitimate UFC competitor in its early days) popularized it in 1997, a wrestler can indicate a voluntary submission by "tapping out", that is, tapping a free hand against the mat or against an opponent. Occasionally, a wrestler will reach for a rope (see rope breaks below), only to put their hand back on the mat so they can crawl towards the rope some more; this is not a submission, and the referee decides what their intent is.
Ans: free hand

Extract the answer to the question from the following context. Question: When was the study of the mind introduced? Context: European comics studies began with Töpffer's theories of his own work in the 1840s, which emphasized panel transitions and the visual–verbal combination. No further progress was made until the 1970s. Pierre Fresnault-Deruelle then took a semiotics approach to the study of comics, analyzing text–image relations, page-level image relations, and image discontinuities, or what Scott McCloud later dubbed "closure". In 1987, Henri Vanlier introduced the term multicadre, or "multiframe", to refer to the comics a page as a semantic unit. By the 1990s, theorists such as Benoît Peeters and Thierry Groensteen turned attention to artists' poïetic creative choices. Thierry Smolderen and Harry Morgan have held relativistic views of the definition of comics, a medium that has taken various, equally valid forms over its history. Morgan sees comics as a subset of "les littératures dessinées" (or "drawn literatures"). French theory has come to give special attention to the page, in distinction from American theories such as McCloud's which focus on panel-to-panel transitions. Since the mid-2000s, Neil Cohn has begun analyzing how comics are understood using tools from cognitive science, extending beyond theory by using actual psychological and neuroscience experiments. This work has argued that sequential images and page layouts both use separate rule-bound "grammars" to be understood that extend beyond panel-to-panel transitions and categorical distinctions of types of layouts, and that the brain's comprehension of comics is similar to comprehending other domains, such as language and music.
Ans: the mid-2000s

Extract the answer to the question from the following context. Question: What Bantu group occupied areas were involved with the passage of goods? Context: Bantu-speaking peoples who founded tribes during the Bantu expansions largely displaced and absorbed the earliest inhabitants of the region, the Pygmy people, about 1500 BC. The Bakongo, a Bantu ethnic group that also occupied parts of present-day Angola, Gabon, and Democratic Republic of the Congo, formed the basis for ethnic affinities and rivalries among those countries. Several Bantu kingdoms—notably those of the Kongo, the Loango, and the Teke—built trade links leading into the Congo River basin.
Ans: the Kongo, the Loango, and the Teke

Extract the answer to the question from the following context. Question: What was the second vaccine produced Context: Early progress toward the development of vaccines occurred throughout this period, primarily in the form of academic and government-funded basic research directed toward the identification of the pathogens responsible for common communicable diseases. In 1885 Louis Pasteur and Pierre Paul Émile Roux created the first rabies vaccine. The first diphtheria vaccines were produced in 1914 from a mixture of diphtheria toxin and antitoxin (produced from the serum of an inoculated animal), but the safety of the inoculation was marginal and it was not widely used. The United States recorded 206,000 cases of diphtheria in 1921 resulting in 15,520 deaths. In 1923 parallel efforts by Gaston Ramon at the Pasteur Institute and Alexander Glenny at the Wellcome Research Laboratories (later part of GlaxoSmithKline) led to the discovery that a safer vaccine could be produced by treating diphtheria toxin with formaldehyde. In 1944, Maurice Hilleman of Squibb Pharmaceuticals developed the first vaccine against Japanese encephelitis. Hilleman would later move to Merck where he would play a key role in the development of vaccines against measles, mumps, chickenpox, rubella, hepatitis A, hepatitis B, and meningitis.
Ans: diphtheria
