Problem: Cyprus:

The physical relief of the island is dominated by two mountain ranges, the Troodos Mountains and the smaller Kyrenia Range, and the central plain they encompass, the Mesaoria. The Mesaoria plain is drained by the Pedieos River, the longest on the island. The Troodos Mountains cover most of the southern and western portions of the island and account for roughly half its area. The highest point on Cyprus is Mount Olympus at 1,952 m (6,404 ft), located in the centre of the Troodos range. The narrow Kyrenia Range, extending along the northern coastline, occupies substantially less area, and elevations are lower, reaching a maximum of 1,024 m (3,360 ft). The island lies within the Anatolian Plate.

A: 1,952 m (6,404 ft)

Problem: Labour Party (UK):

As it was founded by the unions to represent the interests of working-class people, Labour's link with the unions has always been a defining characteristic of the party. In recent years this link has come under increasing strain, with the RMT being expelled from the party in 2004 for allowing its branches in Scotland to affiliate to the left-wing Scottish Socialist Party. Other unions have also faced calls from members to reduce financial support for the Party and seek more effective political representation for their views on privatisation, public spending cuts and the anti-trade union laws. Unison and GMB have both threatened to withdraw funding from constituency MPs and Dave Prentis of UNISON has warned that the union will write "no more blank cheques" and is dissatisfied with "feeding the hand that bites us". Union funding was redesigned in 2013 after the Falkirk candidate-selection controversy.

What is a defining characteristic of the Conservatives?

Problem: Hyderabad:

According to John Everett-Heath, the author of Oxford Concise Dictionary of World Place Names, Hyderabad means "Haydar's city" or "lion city", from haydar (lion) and abad (city). It was named to honour the Caliph Ali Ibn Abi Talib, who was also known as Haydar because of his lion-like valour in battles. Andrew Petersen, a scholar of Islamic architecture, says the city was originally called Baghnagar (city of gardens). One popular theory suggests that Muhammad Quli Qutb Shah, the founder of the city, named it "Bhagyanagar" or "Bhagnagar" after Bhagmati, a local nautch (dancing) girl with whom he had fallen in love. She converted to Islam and adopted the title Hyder Mahal. The city was renamed Hyderabad in her honour. According to another source, the city was named after Haidar, the son of Quli Qutb Shah.

What person is Hyderabad said to have been renamed for?
---
A: "Bhagyanagar" or "Bhagnagar" after Bhagmati, a local nautch (dancing) girl

Problem: Renewable energy commercialization:

The driving force behind voluntary green electricity within the EU are the liberalized electricity markets and the RES Directive. According to the directive the EU Member States must ensure that the origin of electricity produced from renewables can be guaranteed and therefore a "guarantee of origin" must be issued (article 15). Environmental organisations are using the voluntary market to create new renewables and improving sustainability of the existing power production. In the US the main tool to track and stimulate voluntary actions is Green-e program managed by Center for Resource Solutions. In Europe the main voluntary tool used by the NGOs to promote sustainable electricity production is EKOenergy label.

n the US, what is not the main tool to track and stimulate voluntary actions?
