From Lukla, climbers trek upward to the Sherpa capital of Namche Bazaar, 3,440 metres (11,290 ft), following the valley of the Dudh Kosi river. It takes about two days to reach the village, which is a central hub of the area. Typically at this point, climbers allow a day of rest for acclimatization. They then trek another two days to Dingboche, 4,260 metres (13,980 ft) before resting for another day for further acclimatization. Another two days takes them to Everest Base Camp via Gorakshep, the flat field below Kala Patthar, 5,545 metres (18,192 ft) and Mt. Pumori.

Question: how high is Namche Bazaar?
Answer: 3,440 metres (11,290 ft)

Question: What is the elevation of Dingboche in feet?
Answer: 13,980 ft
The Everest Base Camp trek on the south side is one of the most popular trekking routes in the Himalayas and is visited by thousands of trekkers each year. Trekkers usually fly from Kathmandu to Lukla to save time and energy before beginning the trek to this base camp.  However, trekking to Lukla is possible. There are no roads from Kathmandu to Lukla and as a result, the only method of transporting large and heavy goods is by plane.

Question: Why would the trekkers want to fly to Lukla from Kathmandu?
Answer: to save time and energy

Question: What mountains is the Everest Base Camp located?
Answer: Himalayas
At 9:30 am, four men entered classrooms and accommodation blocks, opening fire on teachers and students; they were also armed with suicide vests. The attack happened as the students and faculty members gathered at the school for a poetry recital to commemorate the death anniversary of Gandhian Khan Abdul Ghaffar Khan. The university was reportedly not adequately secured, especially at the backside of the building, which had low boundary walls. Witnesses reported that an assistant professor, armed with a pistol, fired at the assailants.According to provincial Health Minister Shaukat Ali Yousafzai, more than 30 people have been killed and over 60 wounded, including students and an assistant professor. More than 60 students were rescued from the premises. According to an army spokesperson, four gunmen have been killed. Provincial Public Health Engineering Minister Shah Farman said: "54 security guards were stationed at the university. Around 200 people were present in the examination hall, all of whom were rescued, and timely action by police and army has prevented large scale damage". The Education Department in Charsadda has announced the closure of all schools for 10 days.Adnan Khan, a canteen owner in the university saw gunmen entering the university and instructed students to remain silent and turn off their mobile phones thus as a result saved many lives.

Question: How many people died after an assistant professor fired his gun at the university?
Answer: 30
The glomerulus has a glomerular basement membrane (GBM) consisting mainly of laminins, type IV collagen, agrin and nidogen, which are synthesized and secreted by both endothelial cells and podocytes: thus the GBM is sandwiched between the glomerular capillaries and the podocytes. The GBM is 250–400 nm in thickness, which is thicker than basement membranes of other tissue. It is a barrier to blood proteins such as albumin and globulin.The part of the podocyte in contact with the GBM is called a podocyte foot process or pedicle (Fig. 3): there are gaps between the foot processes through which the filtrate flows into Bowman's space of the capsule. . The space between adjacent podocyte foot processes is spanned by slit diaphragms consisting of a mat of proteins, including podocin and nephrin. In addition, foot processes have a negatively charged coat (glycocalyx) that repels negatively charged molecules such as serum albumin.

Question: What is one of the components of slit diaphragms?
Answer: mat of proteins
Among Schiaparelli's contributions are his telescopic observations of Mars. In his initial observations, he named the "seas" and "continents" of Mars. During the planet's "Great Opposition" of 1877, he observed a dense network of linear structures on the surface of Mars which he called "canali" in Italian, meaning "channels" but the term was mistranslated into English as "canals".While the term "canals" indicates an artificial construction, the term "channels" connotes that the observed features were natural configurations of the planetary surface. From the incorrect translation into the term "canals", various assumptions were made about life on Mars; as these assumptions were popularized, the "canals" of Mars became famous, giving rise to waves of hypotheses, speculation, and folklore about the possibility of intelligent life on Mars, the Martians. Among the most fervent supporters of the artificial-canal hypothesis was the American astronomer Percival Lowell, who spent much of his life trying to prove the existence of intelligent life on the red planet. After Lowell's death in 1916, astronomers developed a consensus against the canal hypothesis, but the popular concept of Martian canals excavated by intelligent Martians remained in the public mind for the first half of the 20th century, and inspired a corpus of works of classic science fiction.

Question: Who came up with the hypothesis?
Answer: Percival Lowell

Question: What are hypothetical intelligent life on mars called?
Answer: Martians
An observer of objects in the Solar System, Schiaparelli worked on binary stars, discovered the large main-belt asteroid 69 Hesperia on 29 April 1861, and demonstrated that the meteor showers were associated with comets. He proved, for example, that the orbit of the Leonid meteor shower coincided with that of the comet Tempel-Tuttle. These observations led the astronomer to formulate the hypothesis, subsequently proved to be correct, that the meteor showers could be the trails of comets. He was also a keen observer of the inner planets Mercury and Venus.  He made several drawings and determined their rotation periods.  In 1965, it was shown that his and most other subsequent measurements of Mercury's period were incorrect.Schiaparelli was a scholar of the history of classical astronomy. He was the first to realize that the concentric spheres of Eudoxus of Cnidus and Callippus, unlike those used by many astronomers of later times, were not to be taken as material objects, but only as part of an algorithm similar to the modern Fourier series.

Question: Schiaparelli is known to have proved the association of meteor showers with what?
Answer: trails of comets

January 1998 was also the month that Netscape started the open source Mozilla project. Netscape publicly released the source code of Netscape Communicator 4.0 in the hopes that it would become a popular open source project. It placed this code under the Netscape Public License, which was similar to the GNU General Public License but allowed Netscape to continue to publish proprietary work containing the publicly released code. However, after having released the Communicator 4.0 code this way, Netscape proceeded to work on Communicator 4.5 which was focused on improving email and enterprise functionality. It eventually became clear that the Communicator 4.0 browser was too difficult to develop, and open source development was halted on this codebase. Instead, the open source development shifted to a next-generation browser built from scratch. Using the newly built Gecko layout engine, this browser had a much more modular architecture than Communicator 4.0 and was, therefore, easier to develop with a large number of programmers. It also included an XML user interface language named XUL that allowed single development of a user interface that ran on Windows, Macintosh, and Unix.  The slogan for this open sourcing effort, "Free The Lizard", carried comedic sexual overtones.

Question: Mozilla was actual the product of what other notable web browser?
Answer: Netscape
On November 24, 1998, America Online (AOL) announced it would acquire Netscape Communications in a tax-free stock-swap valued at US$4.2 billion. During this time, Andreessen's view of Netscape changed; to him, it was no longer just a browser, intranet, extranet, or a software company, but rather an amalgamation of products and services. By the time the deal closed on March 17, 1999, it was valued at US$10 billion. This merger was ridiculed by many who believed that the two corporate cultures could not possibly mesh; one of its most prominent critics was longtime Netscape developer Jamie Zawinski. The acquisition was seen as a way for AOL to gain a bargaining chip against Microsoft, to let it become less dependent on the Internet Explorer web browser. Others believed that AOL was interested in Netcenter, or Netscape's web properties, which drew some of the highest traffic worldwide. Eventually, Netscape's server products and its Professional Services group became part of iPlanet, a joint marketing and development alliance between AOL and Sun Microsystems. On November 14, 2000, AOL released Netscape 6, based on the Mozilla 0.6 source code. (Version 5 was skipped.) Unfortunately, Mozilla 0.6 was far from being stable yet, and so the effect of Netscape 6 was to further drive people away from the Netscape brand. It was not until August 2001 that Netscape 6.1 appeared, based on Mozilla 0.9.2 which was significantly more robust. A year later came Netscape 7.0, based on the Mozilla 1.0 core.

Question: How much was AOL acquisition of Netscape estimated to be?
Answer: US$4.2 billion

Question: What made Mozilla 0.9.2 a better base for Netscape?
Answer: more robust
During the mid-2000s, the city witnessed its largest real estate boom since the Florida land boom of the 1920s, and the city had well over a hundred approved high-rise construction projects. However, only 50 were actually built. Rapid high-rise construction led to fast population growth in the Miami's inner neighborhoods, with Downtown, Brickell and Edgewater becoming the fastest-growing areas of the city. Miami's skyline is ranked third-most impressive in the U.S., behind New York City and Chicago, and 19th in the world according to the Almanac of Architecture and Design. The city currently has the seven tallest (as well as fifteen of top twenty) skyscrapers in the state of Florida, with the tallest being the 868-foot (265 m) Panorama Tower.The housing market crash of 2007 caused a foreclosure crisis in the area. In 2012, Forbes magazine named Miami the most miserable city in the United States because of the crippling housing crisis that cost multitudes of residents their homes and jobs. In addition, the metro area has one of the highest violent crime rates in the country and workers face lengthy daily commutes. Like other metro areas in the United States, crime in Miami is localized to specific neighborhoods. In a 2016 study by the website 24/7 Wall Street, Miami was rated as the worst U.S. city in which to live, based on crime, poverty, income inequality and housing costs that far exceed the national median.Miami International Airport (MIA) and PortMiami are among the nation's busiest ports of entry, especially for cargo from South America and the Caribbean. PortMiami is the world's busiest cruise port, and MIA is the busiest airport in Florida and the largest gateway between the United States and Latin America. Due to its strength in international business, finance and trade, the city has among the largest concentration of international banks in the country, primarily along Brickell Avenue in Brickell, Miami's financial district. Miami was the host city of the 2003 Free Trade Area of the Americas negotiations.

Question: What year did the city of Miami host?
Answer: 2003
Spontaneous Raman scattering is typically very weak, and as a result the main difficulty of Raman spectroscopy is separating the weak inelastically scattered light from the intense Rayleigh scattered laser light. Historically, Raman spectrometers used holographic gratings and multiple dispersion stages to achieve a high degree of laser rejection. In the past, photomultipliers were the detectors of choice for dispersive Raman setups, which resulted in long acquisition times. However, modern instrumentation almost universally employs notch or edge filters for laser rejection and spectrographs either axial transmissive (AT), Czerny–Turner (CT) monochromator, or FT (Fourier transform spectroscopy based), and CCD detectors.

Question: What was the negative result caused for using photomultipliers as detectors in dispersive Raman setups?
Answer: long acquisition times
As of September  2018 donations and selling Buddy Bears at auction had generated a total of Euro 2,300,000 in aid of UNICEF and of local organisations helping children in need.

Question: What was sold at auction?
Answer: Buddy Bears
Buddy Bear activities and help for children in need have formed an inseparable unit. New United Buddy Bears are often designed to replace the previous unique sculpture of a particular country. Many countries are already represented with the third or fourth bear. The previous bears designed on behalf of the respective countries are generally sold at auctions.

Question: What is the name of the bear?
Answer: Buddy Bear
Consumption of foods which are themselves vasodilators, such as alcoholic beverages or cinnamon, can increase the probability of an angioedema episode in susceptible patients.  If the episode occurs at all after the consumption of these foods, its onset may be delayed overnight or by some hours, making the correlation with their consumption somewhat difficult. In contrast, consumption of bromelain in combination with turmeric may be beneficial in reducing symptoms.The use of ibuprofen or aspirin may increase the probability of an episode in some patients.  The use of acetaminophen typically has a smaller, but still present, increase in the probability of an episode.

Question: Consuming alcohol can increase what in prone patients?
Answer: probability of an angioedema episode
Salsette Island (Salsete) is an island in the state of Maharashtra on India's west coast. The metropolis of Mumbai (formerly Bombay) and the city of Thane lie on it, making it very populous and one of the most densely populated islands in the world. It has about 15.1 million inhabitants living on an area of about 619 km².

Question: Where is Salsette Island located?
Answer: state of Maharashtra on India's west coast
Antarctica is the coldest of Earth's continents. It used to be ice-free until about 34 million years ago, when it became covered with ice. The coldest natural air temperature ever recorded on Earth was −89.2 °C (−128.6 °F) at the Russian Vostok Station in Antarctica on 21 July 1983. For comparison, this is 10.7 °C (20 °F) colder than subliming dry ice at one atmosphere of partial pressure, but since CO2 only makes up 0.039% of air, temperatures of less than −140 °C (−220 °F) would be needed to produce dry ice snow in Antarctica. A lower air temperature of −94.7 °C (−138.5 °F) was recorded in 2010 by satellite—however, it may be influenced by ground temperatures and was not recorded at a height of 7 feet (2 m) above the surface as required for the official air temperature records. Antarctica is a frozen desert with little precipitation; the South Pole receives less than 10 cm (4 in) per year, on average. Temperatures reach a minimum of between −80 °C (−112 °F) and −89.2 °C (−128.6 °F) in the interior in winter and reach a maximum of between 5 °C (41 °F) and 15 °C (59 °F) near the coast in summer. Sunburn is often a health issue as the snow surface reflects almost all of the ultraviolet light falling on it.  Given the latitude, long periods of constant darkness or constant sunlight create climates unfamiliar to human beings in much of the rest of the world.

Question: Which continent has the lowest average temperature?
Answer: Antarctica
Antarctica, on average, is the coldest, driest, and windiest continent, and has the highest average elevation of all the continents. Most of Antarctica is a polar desert, with annual precipitation of only 200 mm (8 in) along the coast and far less inland. The temperature in Antarctica has reached −89.2 °C (−128.6 °F) (or even −94.7 °C (−135.8 °F) as measured from space), though the average for the third quarter (the coldest part of the year) is −63 °C (−81 °F). Anywhere from 1,000 to 5,000 people reside throughout the year at research stations scattered across the continent. Organisms native to Antarctica include many types of algae, bacteria, fungi, plants, protista, and certain animals, such as mites, nematodes, penguins, seals and tardigrades. Vegetation, where it occurs, is tundra.

Question: Where do the people reside?
Answer: research stations
Explorer James Clark Ross passed through what is now known as the Ross Sea and discovered Ross Island (both of which were named after him) in 1841. He sailed along a huge wall of ice that was later named the Ross Ice Shelf. Mount Erebus and Mount Terror are named after two ships from his expedition: HMS Erebus and Terror. Mercator Cooper landed in East Antarctica on 26 January 1853.During the Nimrod Expedition led by Ernest Shackleton in 1907, parties led by Edgeworth David became the first to climb Mount Erebus and to reach the South Magnetic Pole. Douglas Mawson, who assumed the leadership of the Magnetic Pole party on their perilous return, went on to lead several expeditions until retiring in 1931. In addition, Shackleton and three other members of his expedition made several firsts in December 1908 – February 1909: they were the first humans to traverse the Ross Ice Shelf, the first to traverse the Transantarctic Mountains (via the Beardmore Glacier), and the first to set foot on the South Polar Plateau. An expedition led by Norwegian polar explorer Roald Amundsen from the ship Fram became the first to reach the geographic South Pole on 14 December 1911, using a route from the Bay of Whales and up the Axel Heiberg Glacier. One month later, the doomed Scott Expedition reached the pole.

Question: Who was the head of this journey?
Answer: Roald Amundsen

Question: What did the Scott Expedition reach after a month?
Answer: pole
Vinson Massif, the highest peak in Antarctica at 4,892 m (16,050 ft), is located in the Ellsworth Mountains. Antarctica contains many other mountains, on both the main continent and the surrounding islands. Mount Erebus on Ross Island is the world's southernmost active volcano. Another well-known volcano is found on Deception Island, which is famous for a giant eruption in 1970. Minor eruptions are frequent, and lava flow has been observed in recent years. Other dormant volcanoes may potentially be active. In 2004, a potentially active underwater volcano was found in the Antarctic Peninsula by American and Canadian researchers.Antarctica is home to more than 70 lakes that lie at the base of the continental ice sheet. Lake Vostok, discovered beneath Russia's Vostok Station in 1996, is the largest of these subglacial lakes. It was once believed that the lake had been sealed off for 500,000 to one million years, but a recent survey suggests that, every so often, there are large flows of water from one lake to another.There is some evidence, in the form of ice cores drilled to about 400 m (1,300 ft) above the water line, that Lake Vostok's waters may contain microbial life. The frozen surface of the lake shares similarities with Jupiter's moon, Europa. If life is discovered in Lake Vostok, it would strengthen the argument for the possibility of life on Europa. On 7 February 2008, a NASA team embarked on a mission to Lake Untersee, searching for extremophiles in its highly alkaline waters. If found, these resilient creatures could further bolster the argument for extraterrestrial life in extremely cold, methane-rich environments.In September 2018, researchers at the National Geospatial-Intelligence Agency released a high resolution terrain map (detail down to the size of a car, and less in some areas) of Antarctica, named the "Reference Elevation Model of Antarctica" (REMA).

Question: what are the dimensions of the Antarctica highest peak
Answer: 4,892 m (16,050 ft)
In 1900, Carl Hagenbeck crossed a female leopard with a Bengal tiger. The stillborn offspring had a mixture of spots, rosettes and stripes. Henry Scherren wrote, "A male tiger from Penang served two female Indian leopards, and twice with success. Details are not given and the story concludes somewhat lamely. 'The leopardess dropped her cubs prematurely, the embryos were in the first stage of development and were scarcely as big as young mice.' Of the second leopardess there is no mention."

Question: What kind of tiger was the female leopard crossed with?
Answer: Bengal
K Sankhala's book Tiger refers to large, troublesome leopards as adhabaghera, which he translated as "bastard", and suggests a leopard/tiger hybrid (the reverse hybrid is unlikely to arise in the wild state, as a wild male tiger would probably kill rather than mate with a female leopard). Sankhala noted there was a belief amongst local people that leopards and tigers naturally hybridise.

Question: Who is the author of the book?
Answer: K Sankhala
Reportedly, at the Altiplano Zoo in the city of San Pablo Apetatlan (near Tlaxcala, México), the crossbreeding of a male Siberian tiger and a female jaguar from the southern Chiapas Jungle produced a male tiguar named Mickey. Mickey is on exhibition at a 400 m2 habitat and as of June 2009, was two years old and weighed 180 kg (400 lb). Attempts to verify this report have been bolstered by recent images purported to show the adult Mickey (see External links section). There has been no report of the birth of a healthy hybrid from a male jaguar and female tiger, which would be termed a "jagger".There is a claimed sighting of a lion × black jaguar cross (male) and a tiger × black jaguar cross (female) loose in Maui, Hawaii. There are no authenticated tiger/jaguar hybrids and the description matches that of a liger. The alleged tiger × black jaguar was large, relatively long necked (probably due to lack of a ruff or mane) with both stripes and "jaguar-like" rosettes on its sides. The assertion of hybrid identity was due to the combination of black, dark brown, light brown, dark orange, dark yellow and beige markings and the tiger-like stripes radiating from its face. It is more likely to have been a released liger since these are very large and have a mix of rosettes (lion juvenile markings) and stripes and can have a brindled mix of colours exactly as described (their markings are extremely variable).

Question: What two breeds of animals were crossbred to produce Mickey?
Answer: a male Siberian tiger and a female jaguar

Question: how old was mickey in june 2009?
Answer: two years
