Input: Read this: In 1610, all but three of the survivors of the Sea Venture sailed on to Jamestown. Among them was John Rolfe, whose wife and child died and were buried in Bermuda. Later in Jamestown he married Pocahontas, a daughter of the powerful Powhatan, leader of a large confederation of about 30 Algonquian-speaking tribes in coastal Virginia. In 1612, the English began intentional settlement of Bermuda with the arrival of the ship Plough. St. George's was settled that year and designated as Bermuda's first capital. It is the oldest continually inhabited English town in the New World.
Question: What happened in 1601?

Output: unanswerable

Input: Read this: Agriculture and horticulture seek to optimize the capture of solar energy in order to optimize the productivity of plants. Techniques such as timed planting cycles, tailored row orientation, staggered heights between rows and the mixing of plant varieties can improve crop yields. While sunlight is generally considered a plentiful resource, the exceptions highlight the importance of solar energy to agriculture. During the short growing seasons of the Little Ice Age, French and English farmers employed fruit walls to maximize the collection of solar energy. These walls acted as thermal masses and accelerated ripening by keeping plants warm. Early fruit walls were built perpendicular to the ground and facing south, but over time, sloping walls were developed to make better use of sunlight. In 1699, Nicolas Fatio de Duillier even suggested using a tracking mechanism which could pivot to follow the Sun. Applications of solar energy in agriculture aside from growing crops include pumping water, drying crops, brooding chicks and drying chicken manure. More recently the technology has been embraced by vinters, who use the energy generated by solar panels to power grape presses.
Question: What was the purpose of the fruit walls built by French and English farmers?

Output: acted as thermal masses and accelerated ripening by keeping plants warm

Input: Read this: This method involves coating LEDs of one color (mostly blue LEDs made of InGaN) with phosphors of different colors to form white light; the resultant LEDs are called phosphor-based or phosphor-converted white LEDs (pcLEDs). A fraction of the blue light undergoes the Stokes shift being transformed from shorter wavelengths to longer. Depending on the color of the original LED, phosphors of different colors can be employed. If several phosphor layers of distinct colors are applied, the emitted spectrum is broadened, effectively raising the color rendering index (CRI) value of a given LED.
Question: The different colors of phosphors that can be used is based on what?

Output: the color of the original LED

Input: Read this: The inventor Nicephore Niepce produced the first permanent photograph on a polished pewter plate in Paris in 1825, and then developed the process with Louis Daguerre. The work of Etienne-Jules Marey in the 1880s contributed considerably to the development of modern photography. Photography came to occupy a central role in Parisian Surrealist activity, in the works of Man Ray and Maurice Tabard. Numerous photographers achieved renown for their photography of Paris, including Eugene Atget, noted for his depictions of street scenes, Robert Doisneau, noted for his playful pictures of people and market scenes (among which Le baiser de l'hotel de ville has became iconic of the romantic vision of Paris), Marcel Bovis, noted for his night scenes, and others such as Jacques-Henri Lartigue and Cartier-Bresson. Poster art also became an important art form in Paris in the late nineteenth century, through the work of Henri de Toulouse-Lautrec, Jules Cheret, Eugene Grasset, Adolphe Willette, Pierre Bonnard, Georges de Feure, Henri-Gabriel Ibels, Gavarni, and Alphonse Mucha.
Question: In what year was the first permanent photograph produced?

Output:
1825
