Input: Frederic Chopin
Although this period had been productive, the bad weather had such a detrimental effect on Chopin's health that Sand determined to leave the island. To avoid further customs duties, Sand sold the piano to a local French couple, the Canuts.[n 8] The group traveled first to Barcelona, then to Marseilles, where they stayed for a few months while Chopin convalesced. In May 1839 they headed for the summer to Sand's estate at Nohant, where they spent most summers until 1846. In autumn they returned to Paris, where Chopin's apartment at 5 rue Tronchet was close to Sand's rented accommodation at the rue Pigalle. He frequently visited Sand in the evenings, but both retained some independence. In 1842 he and Sand moved to the Square d'Orleans, living in adjacent buildings.

Who did Sand sell the piano to?
Output: the Canuts.

Input: Database
The relational model also allowed the content of the database to evolve without constant rewriting of links and pointers. The relational part comes from entities referencing other entities in what is known as one-to-many relationship, like a traditional hierarchical model, and many-to-many relationship, like a navigational (network) model. Thus, a relational model can express both hierarchical and navigational models, as well as its native tabular model, allowing for pure or combined modeling in terms of these three models, as the application requires.

What is the relationship called in a navigational model?
Output: many-to-many

Input: University of Notre Dame
Holy Cross Father John Francis O'Hara was elected vice-president in 1933 and president of Notre Dame in 1934. During his tenure at Notre Dame, he brought numerous refugee intellectuals to campus; he selected Frank H. Spearman, Jeremiah D. M. Ford, Irvin Abell, and Josephine Brownson for the Laetare Medal, instituted in 1883. O'Hara strongly believed that the Fighting Irish football team could be an effective means to "acquaint the public with the ideals that dominate" Notre Dame. He wrote, "Notre Dame football is a spiritual service because it is played for the honor and glory of God and of his Blessed Mother. When St. Paul said: 'Whether you eat or drink, or whatsoever else you do, do all for the glory of God,' he included football."

For whos glory did Father O'Hara believed that the Notre Dame football team played?
Output: God

Input: Utrecht
In the early 19th century, the role of Utrecht as a fortified town had become obsolete. The fortifications of the Nieuwe Hollandse Waterlinie were moved east of Utrecht. The town walls could now be demolished to allow for expansion. The moats remained intact and formed an important feature of the Zocher plantsoen, an English style landscape park that remains largely intact today. Growth of the city increased when, in 1843, a railway connecting Utrecht to Amsterdam was opened. After that, Utrecht gradually became the main hub of the Dutch railway network. With the industrial revolution finally gathering speed in the Netherlands and the ramparts taken down, Utrecht began to grow far beyond the medieval centre. In 1853, the Dutch government allowed the bishopric of Utrecht to be reinstated by Rome, and Utrecht became the centre of Dutch Catholicism once more. From the 1880s onward neighbourhoods such as Oudwijk, Wittevrouwen, Vogelenbuurt to the East, and Lombok to the West were developed. New middle class residential areas, such as Tuindorp and Oog in Al, were built in the 1920s and 1930s. During this period, several Jugendstil houses and office buildings were built, followed by Rietveld who built the Rietveld Schroder House (1924), and Dudok's construction of the city theater (1941).
