Problem: Dutch Republic:

In 1582 the United Provinces invited Francis, Duke of Anjou to lead them; but after a failed attempt to take Antwerp in 1583, the duke left the Netherlands again. After the assassination of William of Orange (10 July 1584), both Henry III of France and Elizabeth I of England declined the offer of sovereignty. However, the latter agreed to turn the United Provinces into a protectorate of England (Treaty of Nonsuch, 1585), and sent the Earl of Leicester as governor-general. This was unsuccessful and in 1588 the provinces became a confederacy. The Union of Utrecht is regarded as the foundation of the Republic of the Seven United Provinces, which was not recognized by the Spanish Empire until the Peace of Westphalia in 1648.

What two rulers fought over the provinces after the assassination of William of Orange?

A: unanswerable

Problem: Detroit:

The city of Detroit and other private-public partnerships have attempted to catalyze the region's growth by facilitating the building and historical rehabilitation of residential high-rises in the downtown, creating a zone that offers many business tax incentives, creating recreational spaces such as the Detroit RiverWalk, Campus Martius Park, Dequindre Cut Greenway, and Green Alleys in Midtown. The city itself has cleared sections of land while retaining a number of historically significant vacant buildings in order to spur redevelopment; though it has struggled with finances, the city issued bonds in 2008 to provide funding for ongoing work to demolish blighted properties. Two years earlier, downtown reported $1.3 billion in restorations and new developments which increased the number of construction jobs in the city. In the decade prior to 2006, downtown gained more than $15 billion in new investment from private and public sectors.

Which part of Detroit has gotten billions in investment around the turn of the millennium?
---
A: downtown

Problem: Alloy:

An alloy is a mixture of either pure or fairly pure chemical elements, which forms an impure substance (admixture) that retains the characteristics of a metal. An alloy is distinct from an impure metal, such as wrought iron, in that, with an alloy, the added impurities are usually desirable and will typically have some useful benefit. Alloys are made by mixing two or more elements; at least one of which being a metal. This is usually called the primary metal or the base metal, and the name of this metal may also be the name of the alloy. The other constituents may or may not be metals but, when mixed with the molten base, they will be soluble, dissolving into the mixture.

What kind of substance is an alloy?
---
A: impure

Problem: Late Middle Ages:

Dante Alighieri's Divine Comedy, written in the early 14th century, merged a medieval world view with classical ideals. Another promoter of the Italian language was Boccaccio with his Decameron. The application of the vernacular did not entail a rejection of Latin, and both Dante and Boccaccio wrote prolifically in Latin as well as Italian, as would Petrarch later (whose Canzoniere also promoted the vernacular and whose contents are considered the first modern lyric poems). Together the three poets established the Tuscan dialect as the norm for the modern Italian language.

Whose work, Canzoniere, is considered to be the first example of modern lyric poetry?
---
A:
Petrarch
