Input: Read this: In the post-apartheid era, the Constitution of South Africa has declared the country to be a "Non-racial democracy". In an effort to redress past injustices, the ANC government has introduced laws in support of affirmative action policies for Blacks; under these they define "Black" people to include "Africans", "Coloureds" and "Asians". Some affirmative action policies favor "Africans" over "Coloureds" in terms of qualifying for certain benefits. Some South Africans categorized as "African Black" say that "Coloureds" did not suffer as much as they did during apartheid. "Coloured" South Africans are known to discuss their dilemma by saying, "we were not white enough under apartheid, and we are not black enough under the ANC (African National Congress)".[citation needed]
Question: What did South Africa's Constitution Declare to be?

QUES: President Benito Juarez was re-elected in the general election of 1867 in which he received strong liberal support, especially in Chihuahua. Luis Terrazas was confirmed by the people of Chihuahua to be governor of the state. But soon after the election, President Juarez had another crisis on his hands; the Juarez administration was suspected to be involved in the assassination of the military chief Jose Maria Patoni executed by General Canto in August 1868. General Canto turned himself over to Donato Guerra. Canto was sentenced to death, but later his sentence changed to 10 years imprisonment. The sense of injustice gave rise to a new rebellion in 1869 that threatened the federal government. In response, the Juarez administration took drastic measures by temporarily suspending constitutional rights, but the governor of Chihuahua did not support this action. Hostilities continued to increase especially after the election of 1871 which was perceived to be fraudulent. A new popular leader arose among the rebels, Porfirio Diaz. The federal government was successful in quelling rebellions in Durango an Chihuahua. On July 18, 1872, President Juarez died from a heart attack; soon after, many of his supporters ceased the fighting. Peace returned to Chihuahua and the new government was led by Governor Antonio Ochoa (formerly a co-owner of the Batopilas silver mines) in 1873 after Luis Terrazas finished his term in 1872.

Question: In the 20th century, new types of glass such as laminated glass, reinforced glass and glass bricks have increased the use of glass as a building material and resulted in new applications of glass. Multi-storey buildings are frequently constructed with curtain walls made almost entirely of glass. Similarly, laminated glass has been widely applied to vehicles for windscreens. While glass containers have always been used for storage and are valued for their hygienic properties, glass has been utilized increasingly in industry. Optical glass for spectacles has been used since the late Middle Ages. The production of lenses has become increasingly proficient, aiding astronomers as well as having other application in medicine and science. Glass is also employed as the aperture cover in many solar energy systems.
Try to answer this question if possible: The walls of skyscrapers are often made of what material?
Answer: glass

Input: Read this: The path to independence for the white colonies of the British Empire began with the 1839 Durham Report, which proposed unification and self-government for Upper and Lower Canada, as a solution to political unrest there. This began with the passing of the Act of Union in 1840, which created the Province of Canada. Responsible government was first granted to Nova Scotia in 1848, and was soon extended to the other British North American colonies. With the passage of the British North America Act, 1867 by the British Parliament, Upper and Lower Canada, New Brunswick and Nova Scotia were formed into the Dominion of Canada, a confederation enjoying full self-government with the exception of international relations. Australia and New Zealand achieved similar levels of self-government after 1900, with the Australian colonies federating in 1901. The term "dominion status" was officially introduced at the Colonial Conference of 1907.
Question: When was it proposed to unify Upper and Lower Canada?
