Article: The Han-era family was patrilineal and typically had four to five nuclear family members living in one household. Multiple generations of extended family members did not occupy the same house, unlike families of later dynasties. According to Confucian family norms, various family members were treated with different levels of respect and intimacy. For example, there were different accepted time frames for mourning the death of a father versus a paternal uncle. Arranged marriages were normal, with the father's input on his offspring's spouse being considered more important than the mother's. Monogamous marriages were also normal, although nobles and high officials were wealthy enough to afford and support concubines as additional lovers. Under certain conditions dictated by custom, not law, both men and women were able to divorce their spouses and remarry.

Question: What type of marriage was thought of as a normal occurrence in this era?
Ans: Arranged marriages

Here is a question about this article: The roots of Greek success in the Ottoman Empire can be traced to the Greek tradition of education and commerce. It was the wealth of the extensive merchant class that provided the material basis for the intellectual revival that was the prominent feature of Greek life in the half century and more leading to the outbreak of the Greek War of Independence in 1821. Not coincidentally, on the eve of 1821, the three most important centres of Greek learning were situated in Chios, Smyrna and Aivali, all three major centres of Greek commerce. Greek success was also favoured by Greek domination of the Christian Orthodox church.
What is the answer to this question: Who held much of the wealth in the Greek society ?
****
So... the wealth of the extensive merchant class

The Gospel of Luke begins its account of Mary's life with the Annunciation, when the angel Gabriel appeared to her and announced her divine selection to be the mother of Jesus. According to gospel accounts, Mary was present at the Crucifixion of Jesus and is depicted as a member of the early Christian community in Jerusalem. According to Apocryphal writings, at some time soon after her death, her incorrupt body was assumed directly into Heaven, to be reunited with her soul, and the apostles thereupon found the tomb empty; this is known in Christian teaching as the Assumption.
Which angel appeared to Mary?
****
The answer: Gabriel

Problem: Please answer a question about the following article about Elevator:
In each case, cables are attached to a hitch plate on top of the cab or may be "underslung" below a cab, and then looped over the drive sheave to a counterweight attached to the opposite end of the cables which reduces the amount of power needed to move the cab. The counterweight is located in the hoist-way and rides a separate railway system; as the car goes up, the counterweight goes down, and vice versa. This action is powered by the traction machine which is directed by the controller, typically a relay logic or computerized device that directs starting, acceleration, deceleration and stopping of the elevator cab. The weight of the counterweight is typically equal to the weight of the elevator cab plus 40-50% of the capacity of the elevator. The grooves in the drive sheave are specially designed to prevent the cables from slipping. "Traction" is provided to the ropes by the grip of the grooves in the sheave, thereby the name. As the ropes age and the traction grooves wear, some traction is lost and the ropes must be replaced and the sheave repaired or replaced. Sheave and rope wear may be significantly reduced by ensuring that all ropes have equal tension, thus sharing the load evenly. Rope tension equalization may be achieved using a rope tension gauge, and is a simple way to extend the lifetime of the sheaves and ropes.
The counterweight runs equal to the cab weight plus what percentage of the elevator capacity?
A: 40-50%

During the last decade, Philadelphia experienced a large shift in its age profile. In 2000, the city's population pyramid had a largely stationary shape. In 2013, the city took on an expansive pyramid shape, with an increase in the three millennial age groups, 20 to 24, 25 to 29, and 30 to 34. The city's 25- to 29-year-old age group was the city's largest age cohort. According to the 2010 Census, 343,837 (22.5%) were under the age of 18; 203,697 (13.3%) from 18 to 25; 434,385 (28.5%) from 25 to 44; 358,778 (23.5%) from 45 to 64; and 185,309 (12.1%) who were 65 years of age or older. The median age was 33.5 years. For every 100 females there were 89.4 males. For every 100 females age 18 and over, there were 85.7 males. The city had 22,018 births in 2013, down from a peak 23,689 births in 2008. Philadelphia's death rate was at its lowest in at least a half-century, 13,691 deaths in 2013. Another factor attributing to the population increase is Philadelphia's immigration rate. In 2013, 12.7 percent of residents were foreign-born, just shy of the national average, 13.1 percent.

How many people at the last census were under 18?
Answer: 343,837

One of John's principal challenges was acquiring the large sums of money needed for his proposed campaigns to reclaim Normandy. The Angevin kings had three main sources of income available to them, namely revenue from their personal lands, or demesne; money raised through their rights as a feudal lord; and revenue from taxation. Revenue from the royal demesne was inflexible and had been diminishing slowly since the Norman conquest. Matters were not helped by Richard's sale of many royal properties in 1189, and taxation played a much smaller role in royal income than in later centuries. English kings had widespread feudal rights which could be used to generate income, including the scutage system, in which feudal military service was avoided by a cash payment to the king. He derived income from fines, court fees and the sale of charters and other privileges. John intensified his efforts to maximise all possible sources of income, to the extent that he has been described as "avaricious, miserly, extortionate and moneyminded". John also used revenue generation as a way of exerting political control over the barons: debts owed to the crown by the king's favoured supporters might be forgiven; collection of those owed by enemies was more stringently enforced.
