Problem: Gothic architecture:

At the Abbey Saint-Denis, Noyon Cathedral, Notre Dame de Paris and at the eastern end of Canterbury Cathedral in England, simple cylindrical columns predominate over the Gothic forms of clustered columns and shafted piers. Wells Cathedral in England, commenced at the eastern end in 1175, was the first building in which the designer broke free from Romanesque forms. The architect entirely dispensed with the round arch in favour of the pointed arch and with cylindrical columns in favour of piers composed of clusters of shafts which lead into the mouldings of the arches. The transepts and nave were continued by Adam Locke in the same style and completed in about 1230. The character of the building is entirely Gothic. Wells Cathedral is thus considered the first truly Gothic cathedral.

Problem: By the early 1800s, Indian removal was a significant issue throughout the southeastern U.S. and also in Florida. In 1830, the U.S. Congress passed the Indian Removal Act and as settlement increased, pressure grew on the United States government to remove the Indians from Florida. Seminoles harbored runaway blacks, known as the Black Seminoles, and clashes between whites and Indians grew with the influx of new settlers. In 1832, the Treaty of Payne's Landing promised to the Seminoles lands west of the Mississippi River if they agreed to leave Florida. Many Seminole left at this time.
Who did Seminoles harbor

Answer: runaway blacks, known as the Black Seminoles

Plymouth railway station, which opened in 1877, is managed by Great Western Railway and also sees trains on the CrossCountry network. Smaller stations are served by local trains on the Tamar Valley Line and Cornish Main Line. First Great Western have come under fire recently, due to widespread rail service cuts across the south-west, which affect Plymouth greatly. Three MPs from the three main political parties in the region have lobbied that the train services are vital to its economy.
Trains from what network sometimes operate out of Plymouth's railroad station?
A: CrossCountry


Context and question: Instruments were marketed by teacher-dealers, much as the title character in the popular musical The Music Man. Often, these teacher-dealers conducted mandolin orchestras: groups of 4-50 musicians who played various mandolin family instruments. However, alongside the teacher-dealers were serious musicians, working to create a spot for the instrument in classical music, ragtime and jazz. Like the teacher-dealers, they traveled the U.S., recording records, giving performances and teaching individuals and mandolin orchestras. Samuel Siegel played mandolin in Vaudeville and became one of America's preeminent mandolinists. Seth Weeks was an African American who not only taught and performed in the United States, but also in Europe, where he recorded records. Another pioneering African American musician and director who made his start with a mandolin orchestra was composer James Reese Europe. W. Eugene Page toured the country with a group, and was well known for his mandolin and mandola performances. Other names include Valentine Abt, Samuel Adelstein, William Place, Jr., and Aubrey Stauffer.
What popular musical casted a teacher-dealer? 
Answer: The Music Man


Question: ASCII was incorporated into the Unicode character set as the first 128 symbols, so the 7-bit ASCII characters have the same numeric codes in both sets. This allows UTF-8 to be backward compatible with 7-bit ASCII, as a UTF-8 file containing only ASCII characters is identical to an ASCII file containing the same sequence of characters. Even more importantly, forward compatibility is ensured as software that recognizes only 7-bit ASCII characters as special and does not alter bytes with the highest bit set (as is often done to support 8-bit ASCII extensions such as ISO-8859-1) will preserve UTF-8 data unchanged.
Is there an answer to this question: What is a UTF-8 file containing ISO-8859-1 identical to? 

Answer: unanswerable


QUES: Amensalism is an interaction where an organism inflicts harm to another organism without any costs or benefits received by the other. A clear case of amensalism is where sheep or cattle trample grass. Whilst the presence of the grass causes negligible detrimental effects to the animal's hoof, the grass suffers from being crushed. Amensalism is often used to describe strongly asymmetrical competitive interactions, such as has been observed between the Spanish ibex and weevils of the genus Timarcha which feed upon the same type of shrub. Whilst the presence of the weevil has almost no influence on food availability, the presence of ibex has an enormous detrimental effect on weevil numbers, as they consume significant quantities of plant matter and incidentally ingest the weevils upon it.

What happens when the grass causes damage to an animal's hoof?
