Tea contains more caffeine than coffee by dry weight. A typical serving, however, contains much less, since less of the product is used as compared to an equivalent serving of coffee. Also contributing to caffeine content are growing conditions, processing techniques, and other variables. Thus, teas contain varying amounts of caffeine.Tea contains small amounts of theobromine and slightly higher levels of theophylline than coffee. Preparation and many other factors have a significant impact on tea, and color is a very poor indicator of caffeine content. Teas like the pale Japanese green tea, gyokuro, for example, contain far more caffeine than much darker teas like lapsang souchong, which has very little.

Question: How good of an indicator is color of tea of it caffeine level?
Answer: very poor indicator
Theophylline (4%): Relaxes smooth muscles of the bronchi, and is used to treat asthma. The therapeutic dose of theophylline, however, is many times greater than the levels attained from caffeine metabolism.1,3,7-Trimethyluric acid is a minor caffeine metabolite. Each of these metabolites is further metabolized and then excreted in the urine. Caffeine can accumulate in individuals with severe liver disease, increasing its half-life.A 2011 review found that increased caffeine intake was associated with a variation in two genes that increase the rate of caffeine catabolism. Subjects who had this mutation on both chromosomes consumed 40 mg more caffeine per day than others. This is presumably due to the need for a higher intake to achieve a comparable desired effect, not that the gene led to a disposition for greater incentive of habituation.

Question: What can help heal the pain and agony of asthma?
Answer: Theophylline
Copán is in western Honduras close to the border with Guatemala. It lies within the municipality of Copán Ruinas in the department of Copán.

A central theme of cultural expression is to take the best from the past and discard capitalist elements. Popular, vernacular styles and themes in literature, art, music, and dance are esteemed as expressing the truly unique spirit of the Korean nation. Ethnographers devote much energy to restoring and reintroducing cultural forms that have the proper proletarian or folk spirit and that encourage the development of a collective consciousness. Lively, optimistic musical and choreographic expression are stressed. Group folk dances and choral singing are traditionally practiced in some but not all parts of Korea and were being promoted throughout North Korea in the early 1990s among school and university students. Farmers' musical bands have also been revived.

Question: What is one of the themes of cultural expression?
Answer: take the best from the past and discard capitalist elements
The state and the Korean Workers' Party control the production of literature and art. In the early 1990s, there was no evidence of any underground anti-regime literary or cultural movements such as the samizdat in the Soviet Union or those that exist in the People's Republic of China. The party exercises control over culture through its Propaganda and Agitation Department and the Culture and Arts Department of the KWP's Central Committee. The KWP's General Federation of Korean Literature and Arts Unions, the parent body for all literary and artistic organizations, also directs cultural activity. Due to widespread media control, some analysts have characterized North Koreans as censorees.

Question: Who is in charge of the production of literature and art in Korea?
Answer: The state and the Korean Workers' Party
According to Ottoman tax records, Christians made up roughly 60% of the population in the early 16th century, while the Christian and Muslim population became equal by the mid-16th century. However, there were no Muslim inhabitants counted by the end of the century, with a recorded population of 287 adult male tax-payers. Christians, like all non-Muslims throughout the Ottoman Empire, were required to pay the jizya tax. In 1867, an American visitor describes the town as having a population of 3,000 to 4,000; of whom about 100 were Protestants, 300 were Muslims and "the remainder belonging to the Latin and Greek Churches with a few Armenians." Another report from the same year puts the Christian population at 3,000, with an additional 50 Muslims. An 1885 source put the population at approximately 6,000 of "principally Christians, Latins and Greeks" with no Jewish inhabitants.In 1948, the religious makeup of the city was 85% Christian, mostly of the Greek Orthodox and Roman Catholic denominations, and 13% Muslim.

From 1517, during the years of Ottoman control, custody of the Basilica was bitterly disputed between the Catholic and Greek Orthodox churches. By the end of the 16th century, Bethlehem had become one of the largest villages in the District of Jerusalem, and was subdivided into seven quarters. The Basbus family served as the heads of Bethlehem among other leaders during this period. The Ottoman tax record and census from 1596 indicates that Bethlehem had a population of 1,435, making it the 13th largest village in Palestine at the time. Its total revenue amounted to 30,000 akce.Bethlehem paid taxes on wheat, barley and grapes. The Muslims and Christians were organized into separate communities, each having its own leader. Five leaders represented the village in the mid-16th century, three of whom were Muslims. Ottoman tax records suggest that the Christian population was slightly more prosperous or grew more grain than grapes (the former being a more valuable commodity).From 1831 to 1841, Palestine was under the rule of the Muhammad Ali Dynasty of Egypt. During this period, the town suffered an earthquake as well as the destruction of the Muslim quarter in 1834 by Egyptian troops, apparently as a reprisal for the murder of a favored loyalist of Ibrahim Pasha. In 1841, Bethlehem came under Ottoman rule once again and remained so until the end of World War I. Under the Ottomans, Bethlehem's inhabitants faced unemployment, compulsory military service, and heavy taxes, resulting in mass emigration, particularly to South America. An American missionary in the 1850s reported a population of under 4,000, nearly all of whom belonged to the Greek Church. He also noted that a lack of water crippled the town's growth.Socin found from an official Ottoman village list from about 1870  that  Bethlehem  had  a population of 179 Muslims in 59 houses, 979 "Latins" in 256 houses, 824 "Greeks" in 213 houses, and 41 Armenians in 11 houses, a total of 539 houses. The population count only included men. Hartmann  found that  Bethlehem had 520  houses.

Answer: al-Khader district
The Gospel of Matthew 1:18–2:23 and the Gospel of Luke 2:1–39 represent Jesus as having been born in Bethlehem. Modern scholars, however, regard the two accounts as contradictory and the Gospel of Mark, the earliest gospel, mentions nothing about Jesus having been born in Bethlehem, saying only that he came from Nazareth. Nonetheless, the tradition that Jesus was born in Bethlehem was prominent in the early church. In around 155, the apologist Justin Martyr recommended that those who doubted Jesus was really born in Bethlehem could go there and visit the very cave where he was supposed to have been born. The same cave is also referenced by the apocryphal Gospel of James and the fourth-century church historian Eusebius. After the Bar Kokhba revolt (c. 132–136 CE) was crushed, the Roman emperor Hadrian converted the Christian site above the Grotto into a shrine dedicated to the Greek god Adonis, to honour his favourite, the Greek youth Antinous.In around 395 CE, the Church Father Jerome wrote in a letter: "Bethlehem... belonging now to us... was overshadowed by a grove of Tammuz, that is to say, Adonis, and in the cave where once the infant Christ cried, the lover of Venus was lamented." Many scholars have taken this letter as evidence that the cave of the nativity over which the Church of the Nativity was later built had at one point been a shrine to the ancient Near Eastern fertility god Tammuz. Eusebius, however, mentions nothing about the cave having been associated with Tammuz and there are no other Patristic sources that suggest Tammuz had a shrine in Bethlehem. Peter Welten has argued that the cave was never dedicated to Tammuz and that Jerome misinterpreted Christian mourning over the Massacre of the Innocents as a pagan ritual over Tammuz's death. Joan E. Taylor has countered this contention by arguing that Jerome, as an educated man, could not have been so naïve as to mistake Christian mourning over the Massacre of the Innocents as a pagan ritual for Tammuz.In 326–328, the empress Helena, consort of the emperor Constantius Chlorus, and mother of the emperor Constantine the Great, made a pilgrimage to Syra-Palaestina, in the course of which she visited the ruins of Bethlehem. The Church of the Nativity was built at her initiative over the cave where Jesus was purported to have been born. During the Samaritan revolt of 529, Bethlehem was sacked and its walls and the Church of the Nativity destroyed; they were rebuilt on the orders of the Emperor Justinian I. In 614, the Persian Sassanid Empire, supported by Jewish rebels, invaded Palestina Prima and captured Bethlehem. A story recounted in later sources holds that they refrained from destroying the church on seeing the magi depicted in Persian clothing in a mosaic.

Question: What was refrained from being destroyed?
Answer: the church
The city is located 73 kilometers (45 mi) northeast of Gaza City and the Mediterranean Sea, 75 kilometers (47 mi) west of Amman, Jordan, 59 kilometers (37 mi) southeast of Tel Aviv, Israel and 10 kilometers (6.2 mi) south of Jerusalem. Nearby cities and towns include Beit Safafa and Jerusalem to the north, Beit Jala to the northwest, Husan to the west, al-Khadr and Artas to the southwest, and Beit Sahour to the east. Beit Jala and the latter form an agglomeration with Bethlehem. The Aida and Azza refugee camps are located within the city limits.In the center of Bethlehem is its old city. The old city consists of eight quarters, laid out in a mosaic style, forming the area around the Manger Square. The quarters include the Christian an-Najajreh, al-Farahiyeh, al-Anatreh, al-Tarajmeh, al-Qawawsa and Hreizat quarters and al-Fawaghreh — the only Muslim quarter. Most of the Christian quarters are named after the Arab Ghassanid clans that settled there. Al-Qawawsa Quarter was formed by Arab Christian emigrants from the nearby town of Tuqu' in the 18th century. There is also a Syriac quarter outside of the old city, whose inhabitants originate from Midyat and Ma'asarte in Turkey. The total population of the old city is about 5,000.

Question: How many quarters does the city consist of?
Answer: eight
A special case of natural selection is sexual selection, which is selection for any trait that increases mating success by increasing the attractiveness of an organism to potential mates. Traits that evolved through sexual selection are particularly prominent among males of several animal species. Although sexually favoured, traits such as cumbersome antlers, mating calls, large body size and bright colours often attract predation, which compromises the survival of individual males. This survival disadvantage is balanced by higher reproductive success in males that show these hard-to-fake, sexually selected traits.Natural selection most generally makes nature the measure against which individuals and individual traits, are more or less likely to survive. "Nature" in this sense refers to an ecosystem, that is, a system in which organisms interact with every other element, physical as well as biological, in their local environment. Eugene Odum, a founder of ecology, defined an ecosystem as: "Any unit that includes all of the organisms...in a given area interacting with the physical environment so that a flow of energy leads to clearly defined trophic structure, biotic diversity, and material cycles (i.e., exchange of materials between living and nonliving parts) within the system...." Each population within an ecosystem occupies a distinct niche, or position, with distinct relationships to other parts of the system. These relationships involve the life history of the organism, its position in the food chain and its geographic range. This broad understanding of nature enables scientists to delineate specific forces which, together, comprise natural selection.

Question: What sort of interaction occurs in nature?
Answer: physical as well as biological
