Problem: Armenians:

Armenia established a Church that still exists independently of both the Catholic and the Eastern Orthodox churches, having become so in 451 AD as a result of its stance regarding the Council of Chalcedon. Today this church is known as the Armenian Apostolic Church, which is a part of the Oriental Orthodox communion, not to be confused with the Eastern Orthodox communion. During its later political eclipses, Armenia depended on the church to preserve and protect its unique identity. The original location of the Armenian Catholicosate is Echmiadzin. However, the continuous upheavals, which characterized the political scenes of Armenia, made the political power move to safer places. The Church center moved as well to different locations together with the political authority. Therefore, it eventually moved to Cilicia as the Holy See of Cilicia.

What is Armenia's church called?

A: Armenian Apostolic Church


Problem: Tuvalu:

Reverse osmosis (R/O) desalination units supplement rainwater harvesting on Funafuti. The 65 m3 desalination plant operates at a real production level of around 40 m3 per day. R/O water is only intended to be produced when storage falls below 30%, however demand to replenish household storage supplies with tanker-delivered water means that the R/O desalination units are continually operating. Water is delivered at a cost of A$3.50 per m3. Cost of production and delivery has been estimated at A$6 per m3, with the difference subsidised by the government.

At what storage  point is R/O water production meant to be used?
---
A: below 30%


Problem: Copper:

Copper, silver and gold are in group 11 of the periodic table, and they share certain attributes: they have one s-orbital electron on top of a filled d-electron shell and are characterized by high ductility and electrical conductivity. The filled d-shells in these elements do not contribute much to the interatomic interactions, which are dominated by the s-electrons through metallic bonds. Unlike metals with incomplete d-shells, metallic bonds in copper are lacking a covalent character and are relatively weak. This explains the low hardness and high ductility of single crystals of copper. At the macroscopic scale, introduction of extended defects to the crystal lattice, such as grain boundaries, hinders flow of the material under applied stress, thereby increasing its hardness. For this reason, copper is usually supplied in a fine-grained polycrystalline form, which has greater strength than monocrystalline forms.

What makes copper bondings weaker than other metals?
---
A: filled d-electron shell


Problem: Labour Party (UK):

On 1 March 2014, at a special conference the party reformed internal Labour election procedures, including replacing the electoral college system for selecting new leaders with a "one member, one vote" system following the recommendation of a review by former general-secretary Ray Collins. Mass membership would be encouraged by allowing "registered supporters" to join at a low cost, as well as full membership. Members from the trade unions would also have to explicitly "opt in" rather than "opt out" of paying a political levy to Labour.

What replaced the "one member, one vote" system?
