Input: Read this: At Maecenas' insistence (according to the tradition) Virgil spent the ensuing years (perhaps 37–29 BC) on the long didactic hexameter poem called the Georgics (from Greek, "On Working the Earth") which he dedicated to Maecenas. The ostensible theme of the Georgics is instruction in the methods of running a farm. In handling this theme, Virgil follows in the didactic ("how to") tradition of the Greek poet Hesiod's Works and Days and several works of the later Hellenistic poets. The four books of the Georgics focus respectively on raising crops and trees (1 and 2), livestock and horses (3), and beekeeping and the qualities of bees (4). Well-known passages include the beloved Laus Italiae of Book 2, the prologue description of the temple in Book 3, and the description of the plague at the end of Book 3. Book 4 concludes with a long mythological narrative, in the form of an epyllion which describes vividly the discovery of beekeeping by Aristaeus and the story of Orpheus' journey to the underworld. Ancient scholars, such as Servius, conjectured that the Aristaeus episode replaced, at the emperor's request, a long section in praise of Virgil's friend, the poet Gallus, who was disgraced by Augustus, and who committed suicide in 26 BC.
Question: Who discovered how to raise crops?

Output: unanswerable


QUES: Providing sufficient base drive current is a key problem in the use of bipolar transistors as switches. The transistor provides current gain, allowing a relatively large current in the collector to be switched by a much smaller current into the base terminal. The ratio of these currents varies depending on the type of transistor, and even for a particular type, varies depending on the collector current. In the example light-switch circuit shown, the resistor is chosen to provide enough base current to ensure the transistor will be saturated.

How much current is needed to saturate a light-switch?
What is the answer?
ANS: unanswerable


QUES: In the semiconductor industry, infrared light can be used to characterize materials such as thin films and periodic trench structures. By measuring the reflectance of light from the surface of a semiconductor wafer, the index of refraction (n) and the extinction Coefficient (k) can be determined via the Forouhi-Bloomer dispersion equations. The reflectance from the infrared light can also be used to determine the critical dimension, depth, and sidewall angle of high aspect ratio trench structures.
What letter represents the index of refraction?

ANS: n


The Dutch Republic formally made claim to Saint Helena in 1633, although there is no evidence that they ever occupied, colonised or fortified it. By 1651, the Dutch had mainly abandoned the island in favour of their colony at the Cape of Good Hope.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Which colony did the Dutch abandon the island for?
Ah, so.. Cape of Good Hope.


Question: In 1681, in partial repayment of a debt, Charles II of England granted William Penn a charter for what would become the Pennsylvania colony. Despite the royal charter, Penn bought the land from the local Lenape to be on good terms with the Native Americans and ensure peace for his colony. Penn made a treaty of friendship with Lenape chief Tammany under an elm tree at Shackamaxon, in what is now the city's Fishtown section. Penn named the city Philadelphia, which is Greek for brotherly love (from philos, "love" or "friendship", and adelphos, "brother"). As a Quaker, Penn had experienced religious persecution and wanted his colony to be a place where anyone could worship freely. This tolerance, far more than afforded by most other colonies, led to better relations with the local Native tribes and fostered Philadelphia's rapid growth into America's most important city. Penn planned a city on the Delaware River to serve as a port and place for government. Hoping that Philadelphia would become more like an English rural town instead of a city, Penn laid out roads on a grid plan to keep houses and businesses spread far apart, with areas for gardens and orchards. The city's inhabitants did not follow Penn's plans, as they crowded by the Delaware River, the port, and subdivided and resold their lots. Before Penn left Philadelphia for the last time, he issued the Charter of 1701 establishing it as a city. It became an important trading center, poor at first, but with tolerable living conditions by the 1750s. Benjamin Franklin, a leading citizen, helped improve city services and founded new ones, such as fire protection, a library, and one of the American colonies' first hospitals.
Try to answer this question if possible: When was Philadelphia established as a city?
Answer: 1701


Context and question: The city hosts numerous theatres and production houses, including the Yale Repertory Theatre, the Long Wharf Theatre, and the Shubert Theatre. There is also theatre activity from the Yale School of Drama, which works through the Yale University Theatre and the student-run Yale Cabaret. Southern Connecticut State University hosts the Lyman Center for the Performing Arts. The shuttered Palace Theatre (opposite the Shubert Theatre) is being renovated and will reopen as the College Street Music Hall in May, 2015. Smaller theatres include the Little Theater on Lincoln Street. Cooperative Arts and Humanities High School also boasts a state-of-the-art theatre on College Street. The theatre is used for student productions as well as the home to weekly services to a local non-denominational church, the City Church New Haven.
What was the original name of the College Street Music Hall?
Answer:
Palace Theatre
