In 1987, Corel engineers Michel Bouillon and Pat Beirne undertook to develop a vector-based illustration program to bundle with their desktop publishing systems. That program, CorelDraw, was initially released in 1989. CorelDraw 1.x and 2.x ran under Windows 2.x and 3.0. CorelDraw 3.0 came into its own with Microsoft's release of Windows 3.1. The inclusion of TrueType in Windows 3.1 transformed CorelDraw into a serious illustration program capable of using system-installed outline fonts without requiring third-party software such as Adobe Type Manager; paired with a photo-editing program (Corel Photo-Paint), a font manager and several other pieces of software, it was also part of the first all-in-one graphics suite.

Question: When was CorelDraw released
Answer: 1989
Nickel is a chemical element with the symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel belongs to the transition metals and is hard and ductile. Pure nickel, powdered to maximize the reactive surface area, shows a significant chemical activity, but larger pieces are slow to react with air under standard conditions because an oxide layer forms on the surface and prevents further corrosion (passivation). Even so, pure native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks, and in the interiors of larger nickel–iron meteorites that were not exposed to oxygen when outside Earth's atmosphere.

Question: What color is the tinge?
Answer: silvery-white
Sarawak is divided into three ecoregions. The coastal region is rather low-lying and flat with large areas of swamp and other wet environments. Beaches in Sarawak include Pasir Panjang and Damai beaches in Kuching, Tanjung Batu beach in Bintulu, and Tanjung Lobang and Hawaii beaches in Miri. Hilly terrain accounts for much of the inhabited land and is where most of the cities and towns are found. The ports of Kuching and Sibu are built some distance from the coast on rivers while Bintulu and Miri are close to the coastline where the hills stretch right to the South China Sea. The third region is the mountainous region along the Sarawak–Kalimantan border, where a number of villages such as Bario, Ba'kelalan, and Usun Apau Plieran are located. A number of rivers flow through Sarawak, with the Sarawak River being the main river flowing through Kuching. The Rajang River is the longest river in Malaysia, measuring 563 kilometres (350 mi) including its tributary, Balleh River. To the north, the Baram, Limbang and Trusan Rivers drain into the Brunei Bay.

Question: What type of habitat is found along the coastal region?
Answer: swamp
Messier 81 (also known as NGC 3031 or Bode's Galaxy) is a spiral galaxy about 12 million light-years away, with a diameter of 90,000 light years, about half the size of the Milky Way, in the constellation Ursa Major. Due to its proximity to Earth, large size, and active galactic nucleus (which harbors a 70 million M☉supermassive black hole), Messier 81 has been studied extensively by professional astronomers. The galaxy's large size and relatively high brightness also makes it a popular target for amateur astronomers.Messier 81 was first discovered by Johann Elert Bode on December 31, 1774.  Consequently, the galaxy is sometimes referred to as "Bode's Galaxy".  In 1779, Pierre Méchain and Charles Messier reidentified Bode's object, which was subsequently listed in the Messier Catalogue.

Question: How many light years away is Messier 81 approximately?
Answer: 12 million
Electronic stethoscopes require conversion of acoustic sound waves to electrical signals which can then be amplified and processed for optimal listening. Unlike acoustic stethoscopes, which are all based on the same physics, transducers in electronic stethoscopes vary widely. The simplest and least effective method of sound detection is achieved by placing a microphone in the chestpiece. This method suffers from ambient noise interference and has fallen out of favor. Another method, used in Welch-Allyn's Meditron stethoscope, comprises placement of a piezoelectric crystal at the head of a metal shaft, the bottom of the shaft making contact with a diaphragm. 3M also uses a piezo-electric crystal placed within foam behind a thick rubber-like diaphragm. The Thinklabs' Rhythm 32  uses an electromagnetic diaphragm with a conductive inner surface to form a capacitive sensor. This diaphragm responds to sound waves, with changes in an electric field replacing changes in air pressure.  The Eko Core enables wireless transmission of heart sounds to a smartphone or tablet.

Question: What was the ultimate outcome of the method referenced?
Answer: fallen out of favor
On September 5, 1986, the Boeing 747-121 serving the flight was hijacked while on the ground at Karachi by four armed Palestinian men of the Abu Nidal Organization. The aircraft, with 360 passengers on board, had just arrived from Bombay. A grand jury later concluded that the militants were planning to use the hijacked airliner to pick up Palestinian prisoners in both Cyprus and Israel.Forty-three passengers were injured or killed during the hijacking, including nationals from India, the United States, Pakistan, and Mexico. All the hijackers were arrested and sentenced to death in Pakistan. However, the sentences were later commuted to life in prison. Neerja Bhanot, head attendant on the flight, posthumously received India's highest peacetime award for bravery, the Ashok Chakra Award for her efforts to save passengers' lives during the course of the hijacking.

Question: What sentence did the hijackers get?
Answer: death
Christiaan Huygens  ( HY-gənz, HOY-; Dutch: [ˈɦœyɣə(n)s] (listen); Latin: Hugenius; 14 April 1629 – 8 July 1695) was a Dutch physicist, mathematician, astronomer and inventor, who is widely regarded as one of the greatest scientists of all time and a major figure in the scientific revolution. In physics, Huygens made groundbreaking contributions in optics and mechanics, while as an astronomer he is chiefly known for his studies of the rings of Saturn and the discovery of its moon Titan. As an inventor, he improved the design of the telescope with the invention of the Huygenian eyepiece. His most famous invention, however, was the invention of the pendulum clock in 1656, which was a breakthrough in timekeeping and became the most accurate timekeeper for almost 300 years. Because he was the first to use mathematical formulae to describe the laws of physics, Huygens has been called the first theoretical physicist and the founder of mathematical physics.In 1659, Huygens was the first to derive the now standard formula for the centripetal force in his work De vi centrifuga. The formula played a central role in classical mechanics. Huygens was also the first to formulate the correct laws of elastic collision in his work De motu corporum ex percussione, but his findings were not published until 1703, after his death. In the field of optics, he is best known for his wave theory of light, which he proposed in 1678 and described in 1690 in his Treatise on Light, which is regarded as the first mathematical theory of light. His theory was initially rejected in favor of Isaac Newton's corpuscular theory of light, until Augustin-Jean Fresnel adopted Huygens' principle in 1818 and showed that it could explain the rectilinear propagation and diffraction effects of light. Today this principle is known as the Huygens–Fresnel principle.

Question: On what day of the month was Huygens born?
Answer: 14
The taxonomy of protists is still changing. Newer classifications attempt to present monophyletic groups based on morphological (especially ultrastructural), biochemical (chemotaxonomy) and DNA sequence (molecular research) information. However, there are sometimes discordances between molecular and morphological investigations; these can be categorized as two types: (i) one morphology, multiple lineages (e.g. morphological convergence, cryptic species) and (ii) one lineage, multiple morphologies (e.g. phenotypic plasticity, multiple life-cycle stages).Because the protists as a whole are paraphyletic, new systems often split up or abandon the kingdom, instead treating the protist groups as separate lines of eukaryotes. The recent scheme by Adl et al. (2005) does not recognize formal ranks (phylum, class, etc.) and instead treats groups as clades of phylogenetically related organisms. This is intended to make the classification more stable in the long term and easier to update. Some of the main groups of protists, which may be treated as phyla, are listed in the taxobox, upper right. Many are thought to be monophyletic, though there is still uncertainty. For instance, the Excavata are probably not monophyletic and the chromalveolates are probably only monophyletic if the haptophytes and cryptomonads are excluded.

Question: What is one characteristic of the Excavata?
Answer: not monophyletic
Chichen Itza entered the popular imagination in 1843 with the book Incidents of Travel in Yucatan by John Lloyd Stephens (with illustrations by Frederick Catherwood). The book recounted Stephens' visit to Yucatán and his tour of Maya cities, including Chichén Itzá. The book prompted other explorations of the city. In 1860, Désiré Charnay surveyed Chichén Itzá and took numerous photographs that he published in Cités et ruines américaines (1863).

Question: What was an outcome of the book?
Answer: prompted other explorations of the city
In 1894 the United States Consul to Yucatán, Edward Herbert Thompson, purchased the Hacienda Chichén, which included the ruins of Chichen Itza. For 30 years, Thompson explored the ancient city. His discoveries included the earliest dated carving upon a lintel in the Temple of the Initial Series and the excavation of several graves in the Osario (High Priest's Temple). Thompson is most famous for dredging the Cenote Sagrado (Sacred Cenote) from 1904 to 1910, where he recovered artifacts of gold, copper and carved jade, as well as the first-ever examples of what were believed to be pre-Columbian Maya cloth and wooden weapons. Thompson shipped the bulk of the artifacts to the Peabody Museum at Harvard University.

Question: Which ancient city was explored by Thompson?
Answer: Chichen Itza

Yala (යාල) National Park is the most visited and second largest national park in Sri Lanka, bordering the Indian Ocean. The park consists of five blocks, two of which are now open to the public, and also adjoining parks. The blocks have individual names such as, Ruhuna National Park (Block 1), and Kumana National Park or 'Yala East' for the adjoining area. It is situated in the southeast region of the country, and lies in Southern Province and Uva Province. The park covers 979 square kilometres (378 sq mi) and is located about 300 kilometres (190 mi) from Colombo. Yala was designated as a wildlife sanctuary in 1900, and, along with Wilpattu was one of the first two national parks in Sri Lanka, having been designated in 1938. The park is best known for its variety of wild animals. It is important for the conservation of Sri Lankan elephants, Sri Lankan leopards and aquatic birds.

Question: How many blocks does it consist of?
Answer: five
In atomic theory and quantum mechanics, an atomic orbital is a mathematical function that describes the wave-like behavior of either one electron or a pair of electrons in an atom. This function can be used to calculate the probability of finding any electron of an atom in any specific region around the atom's nucleus. The term atomic orbital may also refer to the physical region or space where the electron can be calculated to be present, as defined by the particular mathematical form of the orbital.Each orbital in an atom is characterized by a unique set of values of the three quantum numbers n, ℓ, and m, which respectively correspond to the electron's energy, angular momentum, and an angular momentum vector component (the magnetic quantum number). Each such orbital can be occupied by a maximum of two electrons, each with its own spin quantum number s. The simple names s orbital, p orbital, d orbital and f orbital refer to orbitals with angular momentum quantum number ℓ = 0, 1, 2 and 3 respectively. These names, together with the value of n, are used to describe the electron configurations of atoms. They are derived from the description by early spectroscopists of certain series of alkali metal spectroscopic lines as sharp, principal, diffuse, and fundamental. Orbitals for ℓ > 3 continue alphabetically, omitting j (g, h, i, k, ...) because some languages do not distinguish between the letters "i" and "j".Atomic orbitals are the basic building blocks of the atomic orbital model (alternatively known as the electron cloud or wave mechanics model), a modern framework for visualizing the submicroscopic behavior of electrons in matter. In this model the electron cloud of a multi-electron atom may be seen as being built up (in approximation) in an electron configuration that is a product of simpler hydrogen-like atomic orbitals. The repeating periodicity of the blocks of 2, 6, 10, and 14 elements within sections of the periodic table arises naturally from the total number of electrons that occupy a complete set of s, p, d and f atomic orbitals, respectively, although for higher values of the quantum number n, particularly when the atom in question bears a positive charge, the energies of certain sub-shells become very similar and so the order in which they are said to be populated by electrons (e.g. Cr = [Ar]4s13d5 and Cr2+ = [Ar]3d4) can only be rationalized somewhat arbitrarily.

Question: The atomic theory helps find electron around what?
Answer: atom's nucleus
Arsia Mons is the southernmost of three volcanos (collectively known as Tharsis Montes) on the Tharsis bulge near the equator of the planet Mars. To its north is Pavonis Mons, and north of that is Ascraeus Mons. The tallest volcano in the Solar System, Olympus Mons, is to its northwest. Its name comes from a corresponding albedo feature on a map by Giovanni Schiaparelli, which he named in turn after the legendary Roman forest of Arsia Silva.

Question: Who created a visual work which depicts the location of places and objects?
Answer: Giovanni Schiaparelli
Although his earliest films did not receive favorable critical attention, he started to receive more positive reviews, beginning with Punch-Drunk Love in 2002. Roger Ebert's review of Punch-Drunk Love concluded that Sandler had been wasted in earlier films with poorly written scripts and characters with no development. Sandler has moved outside the genre of slapstick comedy to take on more serious roles, such as the aforementioned Punch-Drunk Love, for which he was nominated for a Golden Globe, and Mike Binder's Reign Over Me (2007), a drama about a man who loses his entire family in 9/11, and then struggles to rekindle a friendship with his old college roommate (Don Cheadle).

Question: When did Sandler start receiving positive reviews?
Answer: 2002
Early in his career, in 1987, Sandler played Theo Huxtable's friend, Smitty, in The Cosby Show and the Stud Boy or Trivia Delinquent in the MTV game show Remote Control. After his film debut Going Overboard in 1989, Sandler performed in comedy clubs, having first taken the stage at his brother's urging when he was 17. He was discovered by comedian Dennis Miller, who caught Sandler's act in Los Angeles and recommended him to Saturday Night Live producer Lorne Michaels. Sandler was hired as a writer for SNL in 1990 and became a featured player the following year, making a name for himself by performing amusing original songs on the show, including "The Thanksgiving Song" and "The Chanukah Song". Sandler told Conan O'Brien on The Tonight Show that NBC fired him and Chris Farley from the show in 1995, and played this up in his return to the show as a host in 2019.In 1993, Adam Sandler appeared in the film Coneheads with Chris Farley, David Spade, Dan Aykroyd, Phil Hartman, and Jane Curtin. In 1994, he co-starred in Airheads with Brendan Fraser and Steve Buscemi. He starred in Billy Madison (1995) playing a grown man repeating grades 1–12 to earn back his father's respect and the right to inherit his father's multimillion-dollar hotel empire. The film was successful at the box office despite negative reviews. He followed this film with Bulletproof (1996), and the financially successful comedies Happy Gilmore (1996) and The Wedding Singer (1998). He was initially cast in the bachelor party–themed comedy/thriller Very Bad Things (1998) but had to back out due to his involvement in The Waterboy (1998), one of his first hits.

Question: What role did he play in 1995
Answer: Billy Madison

Question: What can cause an avalanche?
Answer: earthquake
Historically, the tasks of local law enforcement, public education, public health, regulating intrastate commerce, and local transportation and infrastructure have generally been considered primarily state responsibilities, although all of these now have significant federal funding and regulation as well. Over time, the Constitution has been amended, and the interpretation and application of its provisions have changed. The general tendency has been toward centralization and incorporation, with the federal government playing a much larger role than it once did. There is a continuing debate over states' rights, which concerns the extent and nature of the states' powers and sovereignty in relation to the federal government and the rights of individuals.

Question: Who, in the past, has had the main jurisdiction over public education and public health
Answer: state

The surface of Amalthea is very red. The reddish color may be due to sulfur originating from Io or some other non-ice material.  Bright patches of less red tint appear on the major slopes of Amalthea, but the nature of this color is currently unknown. The surface of Amalthea is slightly brighter than surfaces of other inner satellites of Jupiter. There is also a substantial asymmetry between leading and trailing hemispheres: the leading hemisphere is 1.3 times brighter than the trailing one. The asymmetry is probably caused by the higher velocity and frequency of impacts on the leading hemisphere, which excavate a bright material—presumably ice—from the interior of the moon.

Question: what is the colour of the amalthea
Answer: red
