QUES: In 1976 John Goldsmith introduced autosegmental phonology. Phonological phenomena are no longer seen as operating on one linear sequence of segments, called phonemes or feature combinations, but rather as involving some parallel sequences of features which reside on multiple tiers. Autosegmental phonology later evolved into feature geometry, which became the standard theory of representation for theories of the organization of phonology as different as lexical phonology and optimality theory.

What did operating tiers morph into?

QUES: In 1644, Rene Descartes theorized that pain was a disturbance that passed down along nerve fibers until the disturbance reached the brain, a development that transformed the perception of pain from a spiritual, mystical experience to a physical, mechanical sensation[citation needed]. Descartes's work, along with Avicenna's, prefigured the 19th-century development of specificity theory. Specificity theory saw pain as "a specific sensation, with its own sensory apparatus independent of touch and other senses". Another theory that came to prominence in the 18th and 19th centuries was intensive theory, which conceived of pain not as a unique sensory modality, but an emotional state produced by stronger than normal stimuli such as intense light, pressure or temperature. By the mid-1890s, specificity was backed mostly by physiologists and physicians, and the intensive theory was mostly backed by psychologists. However, after a series of clinical observations by Henry Head and experiments by Max von Frey, the psychologists migrated to specificity almost en masse, and by century's end, most textbooks on physiology and psychology were presenting pain specificity as fact.

What theory perceives pain as being a specific sensation?
What is the answer?
ANS: Specificity
QUES: Swiss citizens are universally required to buy health insurance from private insurance companies, which in turn are required to accept every applicant. While the cost of the system is among the highest it compares well with other European countries in terms of health outcomes; patients who are citizens have been reported as being, in general, highly satisfied with it. In 2012, life expectancy at birth was 80.4 years for men and 84.7 years for women the highest in the world. However, spending on health is particularly high at 11.4% of GDP (2010), on par with Germany and France (11.6%) and other European countries, and notably less than spending in the USA (17.6%). From 1990, a steady increase can be observed, reflecting the high costs of the services provided. With an ageing population and new healthcare technologies, health spending will likely continue to rise.

What population will cause health spending to likely rise in the future?
What is the answer?
ANS:
ageing
