The problem: Answer a question about this article:
The major time divisions of classical music up to 1900 are the early music period, which includes Medieval (500–1400) and Renaissance (1400–1600) eras, and the Common practice period, which includes the Baroque (1600–1750), Classical (1750–1830) and Romantic (1804–1910) eras. Since 1900, classical periods have been reckoned more by calendar century than by particular stylistic movements that have become fragmented and difficult to define. The 20th century calendar period (1901–2000) includes most of the early modern musical era (1890–1930), the entire high modern (mid 20th-century), and the first 25 years of the contemporary or postmodern musical era (1975–current). The 21st century has so far been characterized by a continuation of the contemporary/postmodern musical era.
What era has the 21st century has been characterized by?
****
The answer: the contemporary/postmodern musical era


Problem: Please answer a question about the following article about PlayStation 3:
The console was first officially announced at E3 2005, and was released at the end of 2006. It was the first console to use Blu-ray Disc as its primary storage medium. The console was the first PlayStation to integrate social gaming services, included it being the first to introduce Sony's social gaming service, PlayStation Network, and its remote connectivity with PlayStation Portable and PlayStation Vita, being able to remote control the console from the devices. In September 2009, the Slim model of the PlayStation 3 was released, being lighter and thinner than the original version, which notably featured a redesigned logo and marketing design, as well as a minor start-up change in software. A Super Slim variation was then released in late 2012, further refining and redesigning the console. As of March 2016, PlayStation 3 has sold 85 million units worldwide. Its successor, the PlayStation 4, was released later in November 2013.
What year did the Super Slim model hit stores?
A: 2012


Question: Read this and answer the question

The first Dominican site in England was at Oxford, in the parishes of St. Edward and St. Adelaide. The friars built an oratory to the Blessed Virgin Mary and by 1265, the brethren, in keeping with their devotion to study, began erecting a school. Actually, the Dominican brothers likely began a school immediately after their arrival, as priories were legally schools. Information about the schools of the English Province is limited, but a few facts are known. Much of the information available is taken from visitation records. The "visitation" was a section of the province through which visitors to each priory could describe the state of its religious life and its studies to the next chapter. There were four such visits in England and Wales—Oxford, London, Cambridge and York. All Dominican students were required to learn grammar, old and new logic, natural philosophy and theology. Of all of the curricular areas, however, theology was the most important. This is not surprising when one remembers Dominic's zeal for it.

What was the most important subject for Dominican students?
Answer: theology


Problem: Natural uranium consists of three major isotopes: uranium-238 (99.28% natural abundance), uranium-235 (0.71%), and uranium-234 (0.0054%). All three are radioactive, emitting alpha particles, with the exception that all three of these isotopes have small probabilities of undergoing spontaneous fission, rather than alpha emission. There are also five other trace isotopes: uranium-239, which is formed when 238U undergoes spontaneous fission, releasing neutrons that are captured by another 238U atom; uranium-237, which is formed when 238U captures a neutron but emits two more, which then decays to neptunium-237; uranium-233, which is formed in the decay chain of that neptunium-237; and finally, uranium-236 and -240, which appear in the decay chain of primordial plutonium-244. It is also expected that thorium-232 should be able to undergo double beta decay, which would produce uranium-232, but this has not yet been observed experimentally.
When uranium isotope is formed from the decay of neptunium-237?
The answer is the following: uranium-233


Input: Article: Historians estimate that between the advent of Islam in 650CE and the abolition of slavery in the Arabian Peninsula in the mid-20th century, 10 to 18 million sub-Saharan Black Africans were enslaved by Arab slave traders and transported to the Arabian Peninsula and neighboring countries. This number far exceeded the number of slaves who were taken to the Americas. Several factors affected the visibility of descendants of this diaspora in 21st-century Arab societies: The traders shipped more female slaves than males, as there was a demand for them to serve as concubines in harems in the Arabian Peninsula and neighboring countries. Male slaves were castrated in order to serve as harem guards. The death toll of Black African slaves from forced labor was high. The mixed-race children of female slaves and Arab owners were assimilated into the Arab owners' families under the patrilineal kinship system. As a result, few distinctive Afro-Arab black communities have survived in the Arabian Peninsula and neighboring countries.

Now answer this question: Why were women slaves more popular?

Output:
for them to serve as concubines
