Input: Article: The simplest model capacitor consists of two thin parallel conductive plates separated by a dielectric with permittivity ε . This model may also be used to make qualitative predictions for other device geometries. The plates are considered to extend uniformly over an area A and a charge density ±ρ = ±Q/A exists on their surface. Assuming that the length and width of the plates are much greater than their separation d, the electric field near the centre of the device will be uniform with the magnitude E = ρ/ε. The voltage is defined as the line integral of the electric field between the plates

Now answer this question: Close to the middle of the capacitor, what equation describes the magnitude of the electric field?

Output: E = ρ/ε


Article: A considerable amount of new knowledge about plant function comes from studies of the molecular genetics of model plants such as the Thale cress, Arabidopsis thaliana, a weedy species in the mustard family (Brassicaceae). The genome or hereditary information contained in the genes of this species is encoded by about 135 million base pairs of DNA, forming one of the smallest genomes among flowering plants. Arabidopsis was the first plant to have its genome sequenced, in 2000. The sequencing of some other relatively small genomes, of rice (Oryza sativa) and Brachypodium distachyon, has made them important model species for understanding the genetics, cellular and molecular biology of cereals, grasses and monocots generally.

Question: What was the first plant to have its genome sequenced?
Ans: Thale cress, Arabidopsis thaliana


Here is a question about this article: Many solar photovoltaic power stations have been built, mainly in Europe. As of July 2012, the largest photovoltaic (PV) power plants in the world are the Agua Caliente Solar Project (USA, 247 MW), Charanka Solar Park (India, 214 MW), Golmud Solar Park (China, 200 MW), Perovo Solar Park (Russia 100 MW), Sarnia Photovoltaic Power Plant (Canada, 97 MW), Brandenburg-Briest Solarpark (Germany 91 MW), Solarpark Finow Tower (Germany 84.7 MW), Montalto di Castro Photovoltaic Power Station (Italy, 84.2 MW), Eggebek Solar Park (Germany 83.6 MW), Senftenberg Solarpark (Germany 82 MW), Finsterwalde Solar Park (Germany, 80.7 MW), Okhotnykovo Solar Park (Russia, 80 MW), Lopburi Solar Farm (Thailand 73.16 MW), Rovigo Photovoltaic Power Plant (Italy, 72 MW), and the Lieberose Photovoltaic Park (Germany, 71.8 MW).
What is the answer to this question: Where have the majority of photovoltaic power stations been built?
****
So... Europe


The problem: Answer a question about this article:
Epic poetry, notably the "acritic songs", flourished during Middle Ages. Two chronicles, one written by Leontios Machairas and the other by Georgios Voustronios, cover the entire Middle Ages until the end of Frankish rule (4th century–1489). Poèmes d'amour written in medieval Greek Cypriot date back from the 16th century. Some of them are actual translations of poems written by Petrarch, Bembo, Ariosto and G. Sannazzaro. Many Cypriot scholars fled Cyprus at troubled times such as Ioannis Kigalas (c. 1622–1687) who migrated from Cyprus to Italy in the 17th century, several of his works have survived in books of other scholars.
What was the time period of Frankish rule?
****
The answer: 4th century–1489


Problem: Please answer a question about the following article about Tucson, Arizona:
Tucson's largest park, Reid Park, is located in midtown and includes Reid Park Zoo and Hi Corbett Field. Speedway Boulevard, a major east-west arterial road in central Tucson, was named the "ugliest street in America" by Life magazine in the early 1970s, quoting Tucson Mayor James Corbett. Despite this, Speedway Boulevard was awarded "Street of the Year" by Arizona Highways in the late 1990s. According to David Leighton, historical writer for the Arizona Daily Star newspaper, Speedway Boulevard derives its name from an old horse racetrack, known as "The Harlem River Speedway," more commonly called "The Speedway," in New York City. The street was called "The Speedway," from 1904 to about 1906 before the word "The" was taken out.
Which newspaper did David Leighton work for?
A: Arizona Daily Star


Question: Read this and answer the question

The painters of the early Renaissance used two traditional lake pigments, made from mixing dye with either chalk or alum, kermes lake, made from kermes insects, and madder lake, made from the rubia tinctorum plant. With the arrival of cochineal, they had a third, carmine, which made a very fine crimson, though it had a tendency to change color if not used carefully. It was used by almost all the great painters of the 15th and 16th centuries, including Rembrandt, Vermeer, Rubens, Anthony van Dyck, Diego Velázquez and Tintoretto. Later it was used by Thomas Gainsborough, Seurat and J.M.W. Turner.

What would to the carmine pigment if not used diligently?
Answer:
change color
