Problem: Please answer a question about the following article about Galicia (Spain):
On the other hand, the lack of an effective royal justice system in the Kingdom led to the social conflict known as the Guerras Irmandinas ('Wars of the brotherhoods'), when leagues of peasants and burghers, with the support of a number of knights, noblemen, and under legal protection offered by the remote king, toppled many of the castles of the Kingdom and briefly drove the noblemen into Portugal and Castile. Soon after, in the late 15th century, in the dynastic conflict between Isabella I of Castile and Joanna La Beltraneja, part of the Galician aristocracy supported Joanna. After Isabella's victory, she initiated an administrative and political reform which the chronicler Jeronimo Zurita defined as "doma del Reino de Galicia": 'It was then when the taming of Galicia began, because not just the local lords and knights, but all the people of that nation were the ones against the others very bold and warlike'. These reforms, while establishing a local government and tribunal (the Real Audiencia del Reino de Galicia) and bringing the nobleman under submission, also brought most Galician monasteries and institutions under Castilian control, in what has been criticized as a process of centralisation. At the same time the kings began to call the Xunta or Cortes of the Kingdom of Galicia, an assembly of deputies or representatives of the cities of the Kingdom, to ask for monetary and military contributions. This assembly soon developed into the voice and legal representation of the Kingdom, and the depositary of its will and laws.
Which two royals were part of the dynastic conflict of the 15th century?
A: Isabella I of Castile and Joanna La Beltraneja

Problem: Elizabeth's only sibling, Princess Margaret, was born in 1930. The two princesses were educated at home under the supervision of their mother and their governess, Marion Crawford, who was casually known as "Crawfie". Lessons concentrated on history, language, literature and music. Crawford published a biography of Elizabeth and Margaret's childhood years entitled The Little Princesses in 1950, much to the dismay of the royal family. The book describes Elizabeth's love of horses and dogs, her orderliness, and her attitude of responsibility. Others echoed such observations: Winston Churchill described Elizabeth when she was two as "a character. She has an air of authority and reflectiveness astonishing in an infant." Her cousin Margaret Rhodes described her as "a jolly little girl, but fundamentally sensible and well-behaved".
Who was Elizabeth only sibling?P
The answer is the following: Princess Margaret

A dense wave of smog began in the Central and Eastern part of China on 2 December 2013 across a distance of around 1,200 kilometres (750 mi), including Tianjin, Hebei, Shandong, Jiangsu, Anhui, Shanghai and Zhejiang. A lack of cold air flow, combined with slow-moving air masses carrying industrial emissions, collected airborne pollutants to form a thick layer of smog over the region. The heavy smog heavily polluted central and southern Jiangsu Province, especially in and around Nanjing, with its AQI pollution Index at "severely polluted" for five straight days and "heavily polluted" for nine. On 3 December 2013, levels of PM2.5 particulate matter average over 943 micrograms per cubic metre, falling to over 338 micrograms per cubic metre on 4 December 2013. Between 3:00 pm, 3 December and 2:00pm, 4 December local time, several expressways from Nanjing to other Jiangsu cities were closed, stranding dozens of passenger buses in Zhongyangmen bus station. From 5 to 6 December, Nanjing issued a red alert for air pollution and closed down all kindergarten through middle schools. Children's Hospital outpatient services increased by 33 percent; general incidence of bronchitis, pneumonia, upper respiratory tract infections significantly increased. The smog dissipated 12 December. Officials blamed the dense pollution on lack of wind, automobile exhaust emissions under low air pressure, and coal-powered district heating system in North China region. Prevailing winds blew low-hanging air masses of factory emissions (mostly SO2) towards China's east coast.
How long was Nanjing ranked as "severely polluted" during this wave?
five straight days

Problem: Please answer a question about the following article about Richmond, Virginia:
On 17 April 1861, five days after the Confederate attack on Fort Sumter, the legislature voted to secede from the United States and joined the Confederacy. Official action came in May, after the Confederacy promised to move its national capital to Richmond. The city was at the end of a long supply line, which made it somewhat difficult to defend, although supplies continued to reach the city by canal and wagon for years, since it was protected by the Army of Northern Virginia and arguably the Confederacy's best troops and commanders. It became the main target of Union armies, especially in the campaigns of 1862 and 1864-5.
Along with 1864-5, what year notably saw US campaigns directed at Richmond?
A:
1862
