Problem: Please answer a question about the following article about Umayyad Caliphate:
The Diwan of Umar, assigning annuities to all Arabs and to the Muslim soldiers of other races, underwent a change in the hands of the Umayyads. The Umayyads meddled with the register and the recipients regarded pensions as the subsistence allowance even without being in active service. Hisham reformed it and paid only to those who participated in battle. On the pattern of the Byzantine system the Umayyads reformed their army organization in general and divided it into five corps: the centre, two wings, vanguards and rearguards, following the same formation while on march or on a battle field. Marwan II (74050) abandoned the old division and introduced Kurdus (cohort), a small compact body. The Umayyad troops were divided into three divisions: infantry, cavalry and artillery. Arab troops were dressed and armed in Greek fashion. The Umayyad cavalry used plain and round saddles. The artillery used arradah (ballista), manjaniq (the mangonel) and dabbabah or kabsh (the battering ram). The heavy engines, siege machines and baggage were carried on camels behind the army.
What did the Umayyads call the mangonel?
A: manjaniq

Phaininda and episkyros were Greek ball games. An image of an episkyros player depicted in low relief on a vase at the National Archaeological Museum of Athens appears on the UEFA European Championship Cup. Athenaeus, writing in 228 AD, referenced the Roman ball game harpastum. Phaininda, episkyros and harpastum were played involving hands and violence. They all appear to have resembled rugby football, wrestling and volleyball more than what is recognizable as modern football. As with pre-codified "mob football", the antecedent of all modern football codes, these three games involved more handling the ball than kicking. Non-competitive games included kemari in Japan, chuk-guk in Korea and woggabaliri in Australia.

What is the name of a similar, non-competitive game in Japan called?
Answer: kemari

Problem: During a period of tough competition between mortgage lenders for revenue and market share, and when the supply of creditworthy borrowers was limited, mortgage lenders relaxed underwriting standards and originated riskier mortgages to less creditworthy borrowers. In the view of some analysts, the relatively conservative government-sponsored enterprises (GSEs) policed mortgage originators and maintained relatively high underwriting standards prior to 2003. However, as market power shifted from securitizers to originators and as intense competition from private securitizers undermined GSE power, mortgage standards declined and risky loans proliferated. The worst loans were originated in 20042007, the years of the most intense competition between securitizers and the lowest market share for the GSEs.
In what year were high underwriting standards relaxed?
The answer is the following: 2003

On 15 October 1969, while paying a visit to the northern town of Las Anod, Somalia's then President Abdirashid Ali Shermarke was shot dead by one of his own bodyguards. His assassination was quickly followed by a military coup d'etat on 21 October 1969 (the day after his funeral), in which the Somali Army seized power without encountering armed opposition essentially a bloodless takeover. The putsch was spearheaded by Major General Mohamed Siad Barre, who at the time commanded the army.
Who was the commander of the army when the coup occurred?
Mohamed Siad Barre

Input: Treaty
There are several reasons an otherwise valid and agreed upon treaty may be rejected as a binding international agreement, most of which involve problems created at the formation of the treaty.[citation needed] For example, the serial Japan-Korea treaties of 1905, 1907 and 1910 were protested; and they were confirmed as "already null and void" in the 1965 Treaty on Basic Relations between Japan and the Republic of Korea.

In what treaty were the serial Japan-Korea treaties of 1905, 1907, and 1910 confirmed as "already null and void?"
Output: the 1965 Treaty on Basic Relations between Japan and the Republic of Korea

Problem: Please answer a question about the following article about Elevator:
Historically, AC motors were used for single or double speed elevator machines on the grounds of cost and lower usage applications where car speed and passenger comfort were less of an issue, but for higher speed, larger capacity elevators, the need for infinitely variable speed control over the traction machine becomes an issue. Therefore, DC machines powered by an AC/DC motor generator were the preferred solution. The MG set also typically powered the relay controller of the elevator, which has the added advantage of electrically isolating the elevators from the rest of a building's electrical system, thus eliminating the transient power spikes in the building's electrical supply caused by the motors starting and stopping (causing lighting to dim every time the elevators are used for example), as well as interference to other electrical equipment caused by the arcing of the relay contactors in the control system.
Why were AC motors used?
A:
cost and lower usage applications where car speed and passenger comfort were less of an issue
