Title: Insect
Topic: Natural sciences

Many of these species have adaptations to help in under-water locomotion. Water beetles and water bugs have legs adapted into paddle-like structures. Dragonfly naiads use jet propulsion, forcibly expelling water out of their rectal chamber. Some species like the water striders are capable of walking on the surface of water. They can do this because their claws are not at the tips of the legs as in most insects, but recessed in a special groove further up the leg; this prevents the claws from piercing the water's surface film. Other insects such as the Rove beetle Stenus are known to emit pygidial gland secretions that reduce surface tension making it possible for them to move on the surface of water by Marangoni propulsion (also known by the German term Entspannungsschwimmen).

Q1: Water beetles have legs of what type of structure?
A1: paddle-like
Q2: Dragonflys use what kind of propulsion?
A2: jet
Q3: Dragonflys shoot water from where?

A5: pygidial
Title: Boston
Topic: Geography and places

Many older buildings in certain areas of Boston are supported by wooden piles driven into the area's fill; these piles remain sound if submerged in water, but are subject to dry rot if exposed to air for long periods. Groundwater levels have been dropping, to varying degrees, in many areas of the city, due in part to an increase in the amount of rainwater discharged directly into sewers rather than absorbed by the ground. A city agency, the Boston Groundwater Trust, coordinates monitoring of groundwater levels throughout the city via a network of public and private monitoring wells. However, Boston's drinking water supply, from the Quabbin and Wachusett Reservoirs to the west, is one of the very few in the country so pure as to satisfy federal water quality standards without filtration.

Q1: Lots of older buildings are supported by what?
A1: wooden piles
Q2: The piles begin to rot if exposed to what?
A2: air
Q3: What has been happening to groundwater levels?
A3: dropping
Q4: Where does the groundwater go instead of into the ground?
A4: directly into sewers
Title: Predation
Topic: Natural sciences

Many organisms (of which humans are prime examples) eat from multiple levels of the food chain and, thus, make this classification problematic. A carnivore may eat both secondary and tertiary consumers, and its prey may itself be difficult to classify for similar reasons. Organisms showing both carnivory and herbivory are known as omnivores. Even herbivores such as the giant panda may supplement their diet with meat. Scavenging of carrion provides a significant part of the diet of some of the most fearsome predators. Carnivorous plants would be very difficult to fit into this classification, producing their own food but also digesting anything that they may trap. Organisms that eat detritivores or parasites would also be difficult to classify by such a scheme.

Q1: Dead animals that died as a result of natural causes or non-fatal injuries are called?
A1: carrion
Q2: Why are species can be difficult to classify because they?
A2: eat from multiple levels of the food chain

A3: Carnivorous plants
Q4: What are organisms called that show carnivory and herbivory?
A4: omnivores
Q5: What can make classification of predators problematic when using a food pyramid?
A5: Many organisms (of which humans are prime examples) eat from multiple levels of the food chain
Q6: Why would carnivourous plants be difficult to classify into a food pyramid?
A6: producing their own food but also digesting anything that they may trap
Q7: Would it be easy or difficult to classify organims that eat parasites in a food pyramid?
A7: difficult
Title: Windows_8
Topic: Engineering and technology

Many other builds were released until the Japan's Developers Day conference, when Steven Sinofsky announced that Windows 8 Release Preview (build 8400) would be released during the first week of June. On May 28, 2012, Windows 8 Release Preview (Standard Simplified Chinese x64 edition, not China-specific version, build 8400) was leaked online on various Chinese and BitTorrent websites. On May 31, 2012, Windows 8 Release Preview was released to the public by Microsoft.

Title: Asthma
Topic: Natural sciences

Many other conditions can cause symptoms similar to those of asthma. In children, other upper airway diseases such as allergic rhinitis and sinusitis should be considered as well as other causes of airway obstruction including: foreign body aspiration, tracheal stenosis or laryngotracheomalacia, vascular rings, enlarged lymph nodes or neck masses. Bronchiolitis and other viral infections may also produce wheezing. In adults, COPD, congestive heart failure, airway masses, as well as drug-induced coughing due to ACE inhibitors should be considered. In both populations vocal cord dysfunction may present similarly.

Q1: What is a condition that can cause symptoms of astham in children?
A1: allergic rhinitis and sinusitis
Q2: What are some other causes of airway obstruction?
A2: foreign body aspiration, tracheal stenosis or laryngotracheomalacia, vascular rings, enlarged lymph nodes or neck masses
Q3: What other conditions can cause wheezing?
A3: Bronchiolitis and other viral infections
Q4: In adults, what conditions can cause the symptoms of asthma?
A4: COPD, congestive heart failure, airway masses, as well as drug-induced coughing due to ACE inhibitors
Title: Database
Topic: Engineering and technology

Many other databases have application software that accesses the database on behalf of end-users, without exposing the DBMS interface directly. Application programmers may use a wire protocol directly, or more likely through an application programming interface. Database designers and database administrators interact with the DBMS through dedicated interfaces to build and maintain the applications' databases, and thus need some more knowledge and understanding about how DBMSs operate and the DBMSs' external interfaces and tuning parameters.

Title: Indigenous_peoples_of_the_Americas
Topic: History

Many parts of the Americas are still populated by indigenous peoples; some countries have sizable populations, especially Belize, Bolivia, Chile, Ecuador, Greenland, Guatemala, Mexico, and Peru. At least a thousand different indigenous languages are spoken in the Americas. Some, such as the Quechuan languages, Aymara, Guaraní, Mayan languages, and Nahuatl, count their speakers in millions. Many also maintain aspects of indigenous cultural practices to varying degrees, including religion, social organization, and subsistence practices. Like most cultures, over time, cultures specific to many indigenous peoples have evolved to incorporate traditional aspects, but also cater to modern needs. Some indigenous peoples still live in relative isolation from Western culture and a few are still counted as uncontacted peoples.

A5: Western culture
Title: Strasbourg
Topic: Geography and places

Many people from Strasbourg were incorporated in the German Army against their will, and were sent to the eastern front, those young men and women were called Malgré-nous. Many tried to escape from the incorporation, join the French Resistance, or desert the Wehrmacht but many couldn't because they were running the risk of having their families sent to work or concentration camps by the Germans. Many of these men, especially those who did not answer the call immediately, were pressured to "volunteer" for service with the SS, often by direct threats on their families. This threat obliged the majority of them to remain in the German army. After the war, the few that survived were often accused of being traitors or collaborationists, because this tough situation was not known in the rest of France, and they had to face the incomprehension of many. In July 1944, 1500 malgré-nous were released from Soviet captivity and sent to Algiers, where they joined the Free French Forces. Nowadays history recognizes the suffering of those people, and museums, public discussions and memorials have been built to commemorate this terrible period of history of this part of Eastern France (Alsace and Moselle). Liberation of Strasbourg took place on 23 November 1944.

Q1: What were the men and women sent to the eastern front against their will called? 
A1: Malgré-nous
Q2: Who sent deserters families to concentration camps?
A2: Germans

A3: Algiers
Q4: When did the liberation of Strasbourg take place?
A4: 23 November 1944
Title: Identity_(social_science)
Topic: Philosophy and religion

Many people gain a sense of positive self-esteem from their identity groups, which furthers a sense of community and belonging. Another issue that researchers have attempted to address is the question of why people engage in discrimination, i.e., why they tend to favor those they consider a part of their "in-group" over those considered to be outsiders. Both questions have been given extensive attention by researchers working in the social identity tradition. For example, in work relating to social identity theory it has been shown that merely crafting cognitive distinction between in- and out-groups can lead to subtle effects on people's evaluations of others (Cote & Levine 2002).

Q1: What do many people gain from their identity groups?
A1: a sense of positive self-esteem
Q2: People favoring those in their group over outsiders, is an example of what?
A2: discrimination
Q3: Belonging and discrimination are both important to researchers working in what tradition?
A3: the social identity tradition
Q4: Distinction between in and out groups has been shown to affect people's evaluations of others in work related to what?
A4: social identity theory
Title: Pesticide
Topic: Natural sciences

Many pesticides can be grouped into chemical families. Prominent insecticide families include organochlorines, organophosphates, and carbamates. Organochlorine hydrocarbons (e.g., DDT) could be separated into dichlorodiphenylethanes, cyclodiene compounds, and other related compounds. They operate by disrupting the sodium/potassium balance of the nerve fiber, forcing the nerve to transmit continuously. Their toxicities vary greatly, but they have been phased out because of their persistence and potential to bioaccumulate.:239–240 Organophosphate and carbamates largely replaced organochlorines. Both operate through inhibiting the enzyme acetylcholinesterase, allowing acetylcholine to transfer nerve impulses indefinitely and causing a variety of symptoms such as weakness or paralysis. Organophosphates are quite toxic to vertebrates, and have in some cases been replaced by less toxic carbamates.:136–137 Thiocarbamate and dithiocarbamates are subclasses of carbamates. Prominent families of herbicides include phenoxy and benzoic acid herbicides (e.g. 2,4-D), triazines (e.g., atrazine), ureas (e.g., diuron), and Chloroacetanilides (e.g., alachlor). Phenoxy compounds tend to selectively kill broad-leaf weeds rather than grasses. The phenoxy and benzoic acid herbicides function similar to plant growth hormones, and grow cells without normal cell division, crushing the plant's nutrient transport system.:300 Triazines interfere with photosynthesis.:335 Many commonly used pesticides are not included in these families, including glyphosate.

Q1: Organochlorine hydrocarbons effect what balance of the nerve fiber?
A1: sodium/potassium
Q2: Why was the use of organochlorine hydrocarbons ended?
A2: because of their persistence and potential to bioaccumulate
Q3: What type of herbicide selectively kills broad leef weeds?
A3: Phenoxy compounds
Q4: What essential plan funtion is interrupted by triazines?
A4: photosynthesis
Q5: Organophospates and carbamates cause which symptoms?
A5: weakness or paralysis

Title: Indigenous_peoples_of_the_Americas
Topic: History

Many pre-Columbian civilizations established characteristics and hallmarks which included permanent or urban settlements, agriculture, civic and monumental architecture, and complex societal hierarchies. Some of these civilizations had long faded by the time of the first significant European and African arrivals (ca. late 15th–early 16th centuries), and are known only through oral history and through archaeological investigations. Others were contemporary with this period, and are also known from historical accounts of the time. A few, such as the Mayan, Olmec, Mixtec, and Nahua peoples, had their own written records. However, the European colonists of the time worked to eliminate non-Christian beliefs, and Christian pyres destroyed many pre-Columbian written records. Only a few documents remained hidden and survived, leaving contemporary historians with glimpses of ancient culture and knowledge.

Title: Pub
Topic: History

Many pubs were drinking establishments, and little emphasis was placed on the serving of food, other than sandwiches and "bar snacks", such as pork scratchings, pickled eggs, salted crisps and peanuts which helped to increase beer sales. In South East England (especially London) it was common until recent times for vendors selling cockles, whelks, mussels, and other shellfish to sell to customers during the evening and at closing time. Many mobile shellfish stalls would set up near pubs, a practice that continues in London's East End. Otherwise, pickled cockles and mussels may be offered by the pub in jars or packets.

Title: Myanmar
Topic: Geography and places

Many religions are practised in Myanmar. Religious edifices and orders have been in existence for many years. Festivals can be held on a grand scale. The Christian and Muslim populations do, however, face religious persecution and it is hard, if not impossible, for non-Buddhists to join the army or get government jobs, the main route to success in the country. Such persecution and targeting of civilians is particularly notable in Eastern Myanmar, where over 3000 villages have been destroyed in the past ten years. More than 200,000 Muslims have fled to Bangladesh over the last 20 years to escape Islamophobic persecution.

Title: 2008_Sichuan_earthquake
Topic: Natural sciences

Many rescue teams, including that of the Taipei Fire Department from Taiwan, were reported ready to join the rescue effort in Sichuan as early as Wednesday. However, the Red Cross Society of China said that (on May 13) "it was inconvenient currently due to the traffic problem to the hardest hit areas closest to the epicenter." The Red Cross Society of China also stated that the disaster areas need tents, medical supplies, drinking water and food; however it recommended donating cash instead of other items, as it had not been possible to reach roads that were completely damaged or places that were blocked off by landslides. Landslides continuously threatened the progress of a search and rescue group of 80 men, each carrying about 40 kg of relief supplies, from a motorized infantry brigade under commander Yang Wenyao, as they tried to reach the ethnically Tibetan village of Sier at a height of 4000 m above sea level in Pingwu county. The extreme terrain conditions precluded the use of helicopter evacuation, and over 300 of the Tibetan villagers were stranded in their demolished village for five days without food and water before the rescue group finally arrived to help the injured and stranded villagers down the mountain.

Q1: What department was ready to join the rescue effort by Wednesday?
A1: the Taipei Fire Department
Q2: How many Tibetan villagers were stranded?
A2: over 300
Q3: What was the reason that many rescue teams could not join the relief efforts?

Title: Alps
Topic: Geography and places

Many rodents such as voles live underground. Marmots live almost exclusively above the tree line as high as 2,700 m (8,858 ft). They hibernate in large groups to provide warmth, and can be found in all areas of the Alps, in large colonies they build beneath the alpine pastures. Golden eagles and bearded vultures are the largest birds to be found in the Alps; they nest high on rocky ledges and can be found at altitudes of 2,400 m (7,874 ft).

Title: University
Topic: Language and literature

Many scholars (including Makdisi) have argued that early medieval universities were influenced by the religious madrasahs in Al-Andalus, the Emirate of Sicily, and the Middle East (during the Crusades). Other scholars see this argument as overstated. Lowe and Yasuhara have recently drawn on the well-documented influences of scholarship from the Islamic world on the universities of Western Europe to call for a reconsideration of the development of higher education, turning away from a concern with local institutional structures to a broader consideration within a global context.

Q1: Madrasas in which specific location are said to have guided the formation of medieval universities?
A1: Al-Andalus
Q2: Al-Andalus was an Emirate of which entity?
A2: Sicily
Q3: Some scholars think that universities come from what, rather than solely local influences?
A3: a global context
Q4: During what notable Middle East conflict is it believed by some that Universities received influence from madrasas?
A4: the Crusades
Title: Unicode
Topic: Engineering and technology

Many scripts, including Arabic and Devanagari, have special orthographic rules that require certain combinations of letterforms to be combined into special ligature forms. The rules governing ligature formation can be quite complex, requiring special script-shaping technologies such as ACE (Arabic Calligraphic Engine by DecoType in the 1980s and used to generate all the Arabic examples in the printed editions of the Unicode Standard), which became the proof of concept for OpenType (by Adobe and Microsoft), Graphite (by SIL International), or AAT (by Apple).

Q1: What does ACE stand for? 
A1: Arabic Calligraphic Engine
Q2: Who created ACE?
A2: DecoType

Title: Light-emitting_diode
Topic: Engineering and technology

Many sensor systems rely on light as the signal source. LEDs are often ideal as a light source due to the requirements of the sensors. LEDs are used as motion sensors, for example in optical computer mice. The Nintendo Wii's sensor bar uses infrared LEDs. Pulse oximeters use them for measuring oxygen saturation. Some flatbed scanners use arrays of RGB LEDs rather than the typical cold-cathode fluorescent lamp as the light source. Having independent control of three illuminated colors allows the scanner to calibrate itself for more accurate color balance, and there is no need for warm-up. Further, its sensors only need be monochromatic, since at any one time the page being scanned is only lit by one color of light. Since LEDs can also be used as photodiodes, they can be used for both photo emission and detection. This could be used, for example, in a touchscreen that registers reflected light from a finger or stylus. Many materials and biological systems are sensitive to, or dependent on, light. Grow lights use LEDs to increase photosynthesis in plants, and bacteria and viruses can be removed from water and other substances using UV LEDs for sterilization.

Q1: What video game console uses infrared LEDs?
A1: Nintendo Wii
Q2: What device uses infrared LEDs to measure oxygen saturation?
A2: Pulse oximeters
Q3: Some flatbed scanners use what type of LED?
A3: RGB LEDs
Q4: By using LEDs, scanners do not have to what?
A4: warm-up
Q5: Grow lights use LEDs for what process?
A5: increase photosynthesis in plants
Title: Bird
Topic: Natural sciences

Many sleeping birds bend their heads over their backs and tuck their bills in their back feathers, although others place their beaks among their breast feathers. Many birds rest on one leg, while some may pull up their legs into their feathers, especially in cold weather. Perching birds have a tendon locking mechanism that helps them hold on to the perch when they are asleep. Many ground birds, such as quails and pheasants, roost in trees. A few parrots of the genus Loriculus roost hanging upside down. Some hummingbirds go into a nightly state of torpor accompanied with a reduction of their metabolic rates. This physiological adaptation shows in nearly a hundred other species, including owlet-nightjars, nightjars, and woodswallows. One species, the common poorwill, even enters a state of hibernation. Birds do not have sweat glands, but they may cool themselves by moving to shade, standing in water, panting, increasing their surface area, fluttering their throat or by using special behaviours like urohidrosis to cool themselves.

Q1: These types of birds have a tendon locking mechanism.
A1: Perching birds
Q2: Where do many ground birds, such as quails and pheasants, roost?
A2: in trees
Q3: A few parrots of what genus roost hanging upside down?

Title: History_of_India
Topic: History

Many smaller clans mentioned within early literature seem to have been present across the rest of the subcontinent. Some of these kings were hereditary; other states elected their rulers. Early "republics" such as the Vajji (or Vriji) confederation centered in the city of Vaishali, existed as early as the 6th century BCE and persisted in some areas until the 4th century CE. The educated speech at that time was Sanskrit, while the languages of the general population of northern India are referred to as Prakrits. Many of the sixteen kingdoms had coalesced to four major ones by 500/400 BCE, by the time of Gautama Buddha. These four were Vatsa, Avanti, Kosala, and Magadha. The Life of Gautam Budhha was mainly associated with these four kingdoms.

Q1: Where was the Vajji confederation located?
A1: Vaishali
Q2: How early did the small republic states exist in India?
A2: 6th century BCE
Q3: Until what century did the republic states endure in India?
A3: 4th century CE
Q4: In what language did the educated Indian speak?
A4: Sanskrit
Q5: What was the general population's common language ?
A5: Prakrits
Title: Race_(human_categorization)
Topic: Natural sciences

Many social scientists have replaced the word race with the word "ethnicity" to refer to self-identifying groups based on beliefs concerning shared culture, ancestry and history. Alongside empirical and conceptual problems with "race", following the Second World War, evolutionary and social scientists were acutely aware of how beliefs about race had been used to justify discrimination, apartheid, slavery, and genocide. This questioning gained momentum in the 1960s during the U.S. civil rights movement and the emergence of numerous anti-colonial movements worldwide. They thus came to believe that race itself is a social construct, a concept that was believed to correspond to an objective reality but which was believed in because of its social functions.

Q1: What word do many social scientists instead of race?
A1: ethnicity
Q2: What had been used to justify discrimination, apartheid, slavery and genocide in WWII?
A2: beliefs about race
Q3: When did the civil rights movement take place?

Title: Bird
Topic: Natural sciences

Many species of birds are economically important. Domesticated and undomesticated birds (poultry and game) are important sources of eggs, meat, and feathers. Songbirds, parrots, and other species are popular as pets. Guano (bird excrement) is harvested for use as a fertilizer. Birds prominently figure throughout human culture. About 120–130 species have become extinct due to human activity since the 17th century, and hundreds more before then. Human activity threatens about 1,200 bird species with extinction, though efforts are underway to protect them. Recreational birdwatching is an important part of the ecotourism industry.

Many species of the second major avialan lineage to diversify, the Euornithes (meaning "true birds", because they include the ancestors of modern birds), were semi-aquatic and specialized in eating fish and other small aquatic organisms. Unlike the enantiornithes, which dominated land-based and arboreal habitats, most early euornithes lacked perching adaptations and seem to have included shorebird-like species, waders, and swimming and diving species. The later included the superficially gull-like Ichthyornis, the Hesperornithiformes, which became so well adapted to hunting fish in marine environments that they lost the ability to fly and became primarily aquatic. The early euornithes also saw the development of many traits associated with modern birds, like strongly keeled breastbones, toothless, beaked portions of their jaws (though most non-avian euornithes retained teeth in other parts of the jaws). Euornithes also included the first avialans to develop true pygostyle and a fully mobile fan of tail feathers, which may have replaced the "hind wing" as the primary mode of aerial maneuverability and braking in flight.

Topic: History

Many sports popular today were formalised by British Public schools and universities in the 19th century. These schools produced the civil servants and military and naval officers required to build and maintain the British empire, and team sports were considered a vital tool for training their students to think and act as part of a team. Former public schoolboys continued to pursue these activities, and founded organisations such as the Football Association (FA). Today's association of football with the working classes began in 1885 when the FA changed its rules to allow professional players.

Many students are involved in community service in one form or another. Annual events include Dance Marathon, a thirty-hour event that raised more than a million dollars for charity in 2011; and Project Pumpkin, a Halloween celebration hosted by the Northwestern Community Development Corps (NCDC) to which more than 800 local children are invited for an afternoon of games and sweets. NCDC's work is to connect hundreds of student volunteers to some twenty volunteer sites in Evanston and Chicago throughout the year. Many students have assisted with the Special Olympics and have taken alternative spring break trips to hundreds of service sites across the United States. Northwestern students also participate in the Freshman Urban Program, a program for students interested in community service. A large and growing number of students participate in the university's Global Engagement Summer Institute (GESI), a group service-learning expedition in Asia, Africa, or Latin America, in conjunction with the Foundation for Sustainable Development.

Many television shows and films have been produced which portray in-character professional wrestlers as protagonists, such as Ready to Rumble, ¡Mucha Lucha!, Nacho Libre, and the Santo film series. In the wildly popular Rocky series of films about the fictional boxer Rocky Balboa, Rocky III saw its hero fighting a "boxer vs. wrestler" exhibition match against the enormous and villainous wrestler "Thunderlips", portrayed by real-life soon-to-be wrestling icon Hulk Hogan. At least two stage plays set in the world of pro wrestling have been produced: The Baron is a comedy that retells the life of an actual performer known as Baron von Raschke. From Parts Unknown... is an award-nominated Canadian drama about the rise and fall of a fictional wrestler. The 2009 South Park episode "W.T.F." played on the soap operatic elements of professional wrestling. One of the lead characters on the Disney Channel series Kim Possible was a huge fan of pro wrestling and actually featured it on an episode (with two former WWE wrestlers voicing the two fictitious wrestlers featured in the episode).
