Problem: Extract the answer to the question from the following context. Question: what event is mentioned first? Context: Following the Fall of Constantinople on 29 May 1453, many Greeks sought better employment and education opportunities by leaving for the West, particularly Italy, Central Europe, Germany and Russia. Greeks are greatly credited for the European cultural revolution, later called, the Renaissance. In Greek-inhabited territory itself, Greeks came to play a leading role in the Ottoman Empire, due in part to the fact that the central hub of the empire, politically, culturally, and socially, was based on Western Thrace and Greek Macedonia, both in Northern Greece, and of course was centred on the mainly Greek-populated, former Byzantine capital, Constantinople. As a direct consequence of this situation, Greek-speakers came to play a hugely important role in the Ottoman trading and diplomatic establishment, as well as in the church. Added to this, in the first half of the Ottoman period men of Greek origin made up a significant proportion of the Ottoman army, navy, and state bureaucracy, having been levied as adolescents (along with especially Albanians and Serbs) into Ottoman service through the devshirme. Many Ottomans of Greek (or Albanian or Serb) origin were therefore to be found within the Ottoman forces which governed the provinces, from Ottoman Egypt, to Ottomans occupied Yemen and Algeria, frequently as provincial governors.

A: the Fall of Constantinople


Problem: Extract the answer to the question from the following context. Question: Where are differences in weather felt? Context: Temperatures in Israel vary widely, especially during the winter. Coastal areas, such as those of Tel Aviv and Haifa, have a typical Mediterranean climate with cool, rainy winters and long, hot summers. The area of Beersheba and the Northern Negev has a semi-arid climate with hot summers, cool winters and fewer rainy days than the Mediterranean climate. The Southern Negev and the Arava areas have desert climate with very hot and dry summers, and mild winters with few days of rain. The highest temperature in the continent of Asia (54.0 °C or 129.2 °F) was recorded in 1942 at Tirat Zvi kibbutz in the northern Jordan river valley.

A: in Israel


Problem: Extract the answer to the question from the following context. Question: Why do scientists seek biological explanations for sexual orientation? Context: Though researchers generally believe that sexual orientation is not determined by any one factor but by a combination of genetic, hormonal, and environmental influences, with biological factors involving a complex interplay of genetic factors and the early uterine environment, they favor biological models for the cause. They believe that sexual orientation is not a choice, and some of them believe that it is established at conception. That is, individuals do not choose to be homosexual, heterosexual, bisexual, or asexual. While current scientific investigation usually seeks to find biological explanations for the adoption of a particular sexual orientation, there are yet no replicated scientific studies supporting any specific biological etiology for sexual orientation. However, scientific studies have found a number of statistical biological differences between gay people and heterosexuals, which may result from the same underlying cause as sexual orientation itself.

A: They believe that sexual orientation is not a choice, and some of them believe that it is established at conception


Problem: Extract the answer to the question from the following context. Question: What church role was only for men? Context: Women in the Middle Ages were officially required to be subordinate to some male, whether their father, husband, or other kinsman. Widows, who were often allowed much control over their own lives, were still restricted legally. Women's work generally consisted of household or other domestically inclined tasks. Peasant women were usually responsible for taking care of the household, child-care, as well as gardening and animal husbandry near the house. They could supplement the household income by spinning or brewing at home. At harvest-time, they were also expected to help with field-work. Townswomen, like peasant women, were responsible for the household, and could also engage in trade. What trades were open to women varied by country and period. Noblewomen were responsible for running a household, and could occasionally be expected to handle estates in the absence of male relatives, but they were usually restricted from participation in military or government affairs. The only role open to women in the Church was that of nuns, as they were unable to become priests.

A:
priests
