Input: Prime minister
Bahrain's prime minister, Sheikh Khalifah bin Sulman Al Khalifah has been in the post since 1970, making him the longest serving non-elected prime minister.

When did Khalifa first take the post of prime minister?
Output: 1970

Input: Article: According to a tradition first reported by Sulcard in about 1080, a church was founded at the site (then known as Thorn Ey (Thorn Island)) in the 7th century, at the time of Mellitus, a Bishop of London. Construction of the present church began in 1245, on the orders of King Henry III.

Now answer this question: In what century was the church established at the location?

Output: 7th century

Article: Although NPOs are permitted to generate surplus revenues, they must be retained by the organization for its self-preservation, expansion, or plans. NPOs have controlling members or a board of directors. Many have paid staff including management, whereas others employ unpaid volunteers and even executives who work with or without compensation (occasionally nominal). In some countries, where there is a token fee, in general it is used to meet legal requirements for establishing a contract between the executive and the organization.

Question: How does an NPO have to handle surplus money?
Ans: they must be retained by the organization for its self-preservation, expansion, or plans

Here is a question about this article: The clergy was divided into two types: the secular clergy, who lived out in the world, and the regular clergy, who lived under a religious rule and were usually monks. Throughout the period monks remained a very small proportion of the population, usually less than one per cent. Most of the regular clergy were drawn from the nobility, the same social class that served as the recruiting ground for the upper levels of the secular clergy. The local parish priests were often drawn from the peasant class. Townsmen were in a somewhat unusual position, as they did not fit into the traditional three-fold division of society into nobles, clergy, and peasants. During the 12th and 13th centuries, the ranks of the townsmen expanded greatly as existing towns grew and new population centres were founded. But throughout the Middle Ages the population of the towns probably never exceeded 10 per cent of the total population.
What is the answer to this question: What percentage of the European population consisted of monks?
****
So... less than one per cent

The problem: Answer a question about this article:
A 2010 study by Bray et al., using SNP microarray techniques and linkage analysis found that when assuming Druze and Palestinian Arab populations to represent the reference to world Jewry ancestor genome, between 35 to 55 percent of the modern Ashkenazi genome can possibly be of European origin, and that European "admixture is considerably higher than previous estimates by studies that used the Y chromosome" with this reference point. Assuming this reference point the linkage disequilibrium in the Ashkenazi Jewish population was interpreted as "matches signs of interbreeding or 'admixture' between Middle Eastern and European populations". On the Bray et al. tree, Ashkenazi Jews were found to be a genetically more divergent population than Russians, Orcadians, French, Basques, Italians, Sardinians and Tuscans. The study also observed that Ashkenazim are more diverse than their Middle Eastern relatives, which was counterintuitive because Ashkenazim are supposed to be a subset, not a superset, of their assumed geographical source population. Bray et al. therefore postulate that these results reflect not the population antiquity but a history of mixing between genetically distinct populations in Europe. However, it's possible that the relaxation of marriage prescription in the ancestors of Ashkenazim that drove their heterozygosity up, while the maintenance of the FBD rule in native Middle Easterners have been keeping their heterozygosity values in check. Ashkenazim distinctiveness as found in the Bray et al. study, therefore, may come from their ethnic endogamy (ethnic inbreeding), which allowed them to "mine" their ancestral gene pool in the context of relative reproductive isolation from European neighbors, and not from clan endogamy (clan inbreeding). Consequently, their higher diversity compared to Middle Easterners stems from the latter's marriage practices, not necessarily from the former's admixture with Europeans.
In one study it was found that the Ashkenazim were more or less diverse than their Middle Eastern relatives?
****
The answer: more diverse

The problem: Answer a question about this article:
A species can be listed in two ways. The United States Fish and Wildlife Service (FWS) or NOAA Fisheries (also called the National Marine Fisheries Service) can directly list a species through its candidate assessment program, or an individual or organizational petition may request that the FWS or NMFS list a species. A "species" under the act can be a true taxonomic species, a subspecies, or in the case of vertebrates, a "distinct population segment." The procedures are the same for both types except with the person/organization petition, there is a 90-day screening period.
How many different ways can a species be added to the endangered list?
****
The answer:
two ways
