Problem: Chinese generals and officials such as Zuo Zongtang led the suppression of rebellions and stood behind the Manchus. When the Tongzhi Emperor came to the throne at the age of five in 1861, these officials rallied around him in what was called the Tongzhi Restoration. Their aim was to adopt western military technology in order to preserve Confucian values. Zeng Guofan, in alliance with Prince Gong, sponsored the rise of younger officials such as Li Hongzhang, who put the dynasty back on its feet financially and instituted the Self-Strengthening Movement. The reformers then proceeded with institutional reforms, including China's first unified ministry of foreign affairs, the Zongli Yamen; allowing foreign diplomats to reside in the capital; establishment of the Imperial Maritime Customs Service; the formation of modernized armies, such as the Beiyang Army, as well as a navy; and the purchase from Europeans of armament factories.
What year did Tongzhi take power?
The answer is the following: 1861

Problem: Deciduous trees and plants have been promoted as a means of controlling solar heating and cooling. When planted on the southern side of a building in the northern hemisphere or the northern side in the southern hemisphere, their leaves provide shade during the summer, while the bare limbs allow light to pass during the winter. Since bare, leafless trees shade 1/3 to 1/2 of incident solar radiation, there is a balance between the benefits of summer shading and the corresponding loss of winter heating. In climates with significant heating loads, deciduous trees should not be planted on the Equator facing side of a building because they will interfere with winter solar availability. They can, however, be used on the east and west sides to provide a degree of summer shading without appreciably affecting winter solar gain.
Why should trees not be planted on the side of a building facing the equator?
The answer is the following: they will interfere with winter solar availability

Problem:
Australia: The event was held in Canberra, Australian Capital Territory on April 24, and covered around 16 km of Canberra's central areas, from Reconciliation Place to Commonwealth Park. Upon its arrival in Canberra, the Olympic flame was presented by Chinese officials to local Aboriginal elder Agnes Shea, of the Ngunnawal people. She, in turn, offered them a message stick, as a gift of peace and welcome. Hundreds of pro-Tibet protesters and thousands of Chinese students reportedly attended. Demonstrators and counter-demonstrators were kept apart by the Australian Federal Police. Preparations for the event were marred by a disagreement over the role of the Chinese flame attendants, with Australian and Chinese officials arguing publicly over their function and prerogatives during a press conference.
Who received the flame from Chinese officials in Canberra?
The answer is the following: Agnes Shea

Problem: In the first 200 years that black people were in the United States, they primarily identified themselves by their specific ethnic group (closely allied to language) and not by skin color. Individuals identified themselves, for example, as Ashanti, Igbo, Bakongo, or Wolof. However, when the first captives were brought to the Americas, they were often combined with other groups from West Africa, and individual ethnic affiliations were not generally acknowledged by English colonists. In areas of the Upper South, different ethnic groups were brought together. This is significant as the captives came from a vast geographic region: the West African coastline stretching from Senegal to Angola and in some cases from the south-east coast such as Mozambique. A new African-American identity and culture was born that incorporated elements of the various ethnic groups and of European cultural heritage, resulting in fusions such as the Black church and Black English. This new identity was based on provenance and slave status rather than membership in any one ethnic group.[citation needed] By contrast, slave records from Louisiana show that the French and Spanish colonists recorded more complete identities of the West Africans, including ethnicities and given tribal names.
Which colonists recorded more complete identities of the West Africans?
The answer is the following:
French and Spanish colonists
