Problem: Digestion:

Teeth (singular tooth) are small whitish structures found in the jaws (or mouths) of many vertebrates that are used to tear, scrape, milk and chew food. Teeth are not made of bone, but rather of tissues of varying density and hardness, such as enamel, dentine and cementum. Human teeth have a blood and nerve supply which enables proprioception. This is the ability of sensation when chewing, for example if we were to bite into something too hard for our teeth, such as a chipped plate mixed in food, our teeth send a message to our brain and we realise that it cannot be chewed, so we stop trying.

Where are teeth found?

A: in the jaws (or mouths)


Problem: The city is home to 15 am and FM radio stations, two of which are French-language stations. St. John's is the only Canadian city served by radio stations whose call letters do not all begin with the letter C. The ITU prefix VO was assigned to the Dominion of Newfoundland before the province joined Canadian Confederation in 1949, and three AM stations kept their existing call letters. However, other commercial radio stations in St. John's which went to air after 1949 use the same range of prefixes (CF–CK) currently in use elsewhere in Canada, with the exception of VOCM-FM, which was permitted to adopt the VOCM callsign because of its corporate association with the AM station that already bore that callsign. VO also remains in use in amateur radio.
How many French-language stations does the city have?

Answer: two


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The main campus in Provo, Utah, United States sits on approximately 560 acres (2.3 km2) nestled at the base of the Wasatch Mountains and includes 295 buildings. The buildings feature a wide variety of architectural styles, each building being built in the style of its time. The grass, trees, and flower beds on BYU's campus are impeccably maintained. Furthermore, views of the Wasatch Mountains, (including Mount Timpanogos) can be seen from the campus. BYU's Harold B. Lee Library (also known as "HBLL"), which The Princeton Review ranked as the No. 1 "Great College Library" in 2004, has approximately 8½ million items in its collections, contains 98 miles (158 km) of shelving, and can seat 4,600 people. The Spencer W. Kimball Tower, shortened to SWKT and pronounced Swicket by many students, is home to several of the university's departments and programs and is the tallest building in Provo, Utah. Furthermore, BYU's Marriott Center, used as a basketball arena, can seat over 22,000 and is one of the largest on-campus arenas in the nation. Interestingly absent on the campus of this church owned university is a campus chapel. Notwithstanding, each Sunday LDS Church services for students are conducted on campus, but due to the large number of students attending these services, nearly all of the buildings and possible meeting spaces on campus are utilized (in addition, many students attend services off campus in LDS chapels in the surrounding communities).
How many buildings are on BYU's main campus?
A: 295


Context and question: While slaveholding was slightly less concentrated than in some Southern states, according to the 1860 census, more than 330,000 people, or 33% of the population of 992,622, were enslaved African Americans. They lived and worked chiefly on plantations in the eastern Tidewater. In addition, 30,463 free people of color lived in the state. They were also concentrated in the eastern coastal plain, especially at port cities such as Wilmington and New Bern, where a variety of jobs were available. Free African Americans were allowed to vote until 1835, when the state revoked their suffrage in restrictions following the slave rebellion of 1831 led by Nat Turner. Southern slave codes criminalized willful killing of a slave in most cases.
What type of land did the slaves live on?
Answer: plantations


Question: Surface-mount technology emerged in the 1960s, gained momentum in the early 1980s and became widely used by the mid-1990s. Components were mechanically redesigned to have small metal tabs or end caps that could be soldered directly onto the PCB surface, instead of wire leads to pass through holes. Components became much smaller and component placement on both sides of the board became more common than with through-hole mounting, allowing much smaller PCB assemblies with much higher circuit densities. Surface mounting lends itself well to a high degree of automation, reducing labor costs and greatly increasing production rates. Components can be supplied mounted on carrier tapes. Surface mount components can be about one-quarter to one-tenth of the size and weight of through-hole components, and passive components much cheaper; prices of semiconductor surface mount devices (SMDs) are determined more by the chip itself than the package, with little price advantage over larger packages. Some wire-ended components, such as 1N4148 small-signal switch diodes, are actually significantly cheaper than SMD equivalents.
Is there an answer to this question: Is it the chip or the package that influences the price of an SMD more?

Answer: chip


Question: The first post-Classical published classification of humans into distinct races seems to be François Bernier's Nouvelle division de la terre par les différents espèces ou races qui l'habitent ("New division of Earth by the different species or races which inhabit it"), published in 1684. In the 18th century the differences among human groups became a focus of scientific investigation. But the scientific classification of phenotypic variation was frequently coupled with racist ideas about innate predispositions of different groups, always attributing the most desirable features to the White, European race and arranging the other races along a continuum of progressively undesirable attributes. The 1735 classification of Carl Linnaeus, inventor of zoological taxonomy, divided the human race Homo sapiens into continental varieties of europaeus, asiaticus, americanus, and afer, each associated with a different humour: sanguine, melancholic, choleric, and phlegmatic, respectively. Homo sapiens europaeus was described as active, acute, and adventurous, whereas Homo sapiens afer was said to be crafty, lazy, and careless.
Is there an answer to this question: What race was typically ascribed the most desirable features?

Answer:
White
