Question: Read this and answer the question

Due to recording mastering and manufacturing limitations, both high and low frequencies were removed from the first recorded signals by various formulae. With low frequencies, the stylus must swing a long way from side to side, requiring the groove to be wide, taking up more space and limiting the playing time of the record. At high frequencies, hiss, pops, and ticks are significant. These problems can be reduced by using equalization to an agreed standard. During recording the amplitude of low frequencies is reduced, thus reducing the groove width required, and the amplitude at high frequencies is increased. The playback equipment boosts bass and cuts treble so as to restore the tonal balance in the original signal; this also reduces the high frequency noise. Thus more music will fit on the record, and noise is reduced.

What is a benefit of using equalization devices?
Answer: problems can be reduced


Problem: At the level of the individual, there is a large literature, generally related to the work of Jacob Mincer, on how earnings are related to the schooling and other human capital. This work has motivated a large number of studies, but is also controversial. The chief controversies revolve around how to interpret the impact of schooling. Some students who have indicated a high potential for learning, by testing with a high intelligence quotient, may not achieve their full academic potential, due to financial difficulties.[citation needed]
This view of how schooling and earnings has sparked a lot of studies, but what else has it brought up?
The answer is the following: is also controversial


The Reconquista of Portugal and Spain led to a series of oceanic explorations resulting in the Age of Discovery that established direct links with Africa, the Americas, and Asia, while religious wars continued to be fought in Europe, which ended in 1648 with the Peace of Westphalia. The Spanish crown maintained its hegemony in Europe and was the leading power on the continent until the signing of the Treaty of the Pyrenees, which ended a conflict between Spain and France that had begun during the Thirty Years' War. An unprecedented series of major wars and political revolutions took place around Europe and indeed the world in the period between 1610 and 1700. Observers at the time, and many historians since, have argued that wars caused the revolutions. Galileo Galilei, invented the telescope and the thermometer which allowed him to observe and describe the solar system. Leonardo da Vinci painted the most famous work in the world. Guglielmo Marconi invented the radio.
Between which two nations was the Treaty of the Pyrenees signed?
Spain and France


Input: Christian
Another Arabic word sometimes used for Christians, particularly in a political context, is Ṣalībī (صليبي "Crusader") from ṣalīb (صليب "cross") which refers to Crusaders and has negative connotations. However, Salibi is a modern term; historically, Muslim writers described European Christian Crusaders as al-Faranj or Alfranj (الفرنج) and Firinjīyah (الفرنجيّة) in Arabic" This word comes from the Franks and can be seen in the Arab history text Al-Kamil fi al-Tarikh by Ali ibn al-Athir.

Ṣalībī comes from the word ṣalīb, which means what?
Output: cross


Input: Article: According to the latest International Monetary Fund estimates, its per capita GDP (adjusted for purchasing power) at $30,769 is just above the average of the European Union.[citation needed] Cyprus has been sought as a base for several offshore businesses for its low tax rates. Tourism, financial services and shipping are significant parts of the economy. Economic policy of the Cyprus government has focused on meeting the criteria for admission to the European Union. The Cypriot government adopted the euro as the national currency on 1 January 2008.

Now answer this question: When was the Euro declared as the national currency of Cyprus?

Output: 1 January 2008


Problem: Anthropologists have contributed to the debate by shifting the focus of research: One of the first challenges for the researcher wishing to carry out empirical research in this area is to identify an appropriate analytical tool. The concept of boundaries is useful here for demonstrating how identity works. In the same way as Barth, in his approach to ethnicity, advocated the critical focus for investigation as being "the ethnic boundary that defines the group rather than the cultural stuff that it encloses" (1969:15), social anthropologists such as Cohen and Bray have shifted the focus of analytical study from identity to the boundaries that are used for purposes of identification. If identity is a kind of virtual site in which the dynamic processes and markers used for identification are made apparent, boundaries provide the framework on which this virtual site is built. They concentrated on how the idea of community belonging is differently constructed by individual members and how individuals within the group conceive ethnic boundaries.
Boundaries are frequently used by researchers to help define what?
The answer is the following:
identity
