Problem: The first attempt to establish a proper governing body and adopted the current set of Rugby rules was the Foot Ball Association of Canada, organized on March 24, 1873 followed by the Canadian Rugby Football Union (CRFU) founded June 12, 1880, which included teams from Ontario and Quebec. Later both the Ontario and Quebec Rugby Football Union (ORFU and QRFU) were formed (January 1883), and then the Interprovincial (1907) and Western Interprovincial Football Union (1936) (IRFU and WIFU). The CRFU reorganized into an umbrella organization forming the Canadian Rugby Union (CRU) in 1891. The original forerunners to the current Canadian Football League, was established in 1956 when the IRFU and WIFU formed an umbrella organization, The Canadian Football Council (CFC). And then in 1958 the CFC left The CRFU to become The CFL.
When did the Football Association of Canada reorganize to form CRU?

Problem: Hydrogen production technologies been a significant area of solar chemical research since the 1970s. Aside from electrolysis driven by photovoltaic or photochemical cells, several thermochemical processes have also been explored. One such route uses concentrators to split water into oxygen and hydrogen at high temperatures (2,300–2,600 °C or 4,200–4,700 °F). Another approach uses the heat from solar concentrators to drive the steam reformation of natural gas thereby increasing the overall hydrogen yield compared to conventional reforming methods. Thermochemical cycles characterized by the decomposition and regeneration of reactants present another avenue for hydrogen production. The Solzinc process under development at the Weizmann Institute uses a 1 MW solar furnace to decompose zinc oxide (ZnO) at temperatures above 1,200 °C (2,200 °F). This initial reaction produces pure zinc, which can subsequently be reacted with water to produce hydrogen.
The Solznic process produces what?
---
Answer: pure zinc


Problem: Eritrea is a multilingual country. The nation has no official language, as the Constitution establishes the "equality of all Eritrean languages". However, Tigrinya serves as the de facto language of national identity. With 2,540,000 total speakers of a population of 5,254,000 in 2006, Tigrinya is the most widely spoken language, particularly in the southern and central parts of Eritrea. Modern Standard Arabic and English serve as de facto working languages, with the latter used in university education and many technical fields. Italian, the former colonial language, is widely used in commerce and is taught as a second language in schools, with a few elderly monolinguals.
What is the official language of Eritrea?

Answer:
The nation has no official language
