Here is a question about this article: On 16 August 1960, Cyprus attained independence after the Zurich and London Agreement between the United Kingdom, Greece and Turkey. Cyprus had a total population of 573,566; of whom 442,138 (77.1%) were Greeks, 104,320 (18.2%) Turks, and 27,108 (4.7%) others The UK retained the two Sovereign Base Areas of Akrotiri and Dhekelia, while government posts and public offices were allocated by ethnic quotas, giving the minority Turkish Cypriots a permanent veto, 30% in parliament and administration, and granting the three mother-states guarantor rights.
What is the answer to this question: Which countries were part of the Zurich and London Agreement?
****
So... United Kingdom, Greece and Turkey

Here is a question about this article: Renewable energy is also the most economic solution for new grid-connected capacity in areas with good resources. As the cost of renewable power falls, the scope of economically viable applications increases. Renewable technologies are now often the most economic solution for new generating capacity. Where "oil-fired generation is the predominant power generation source (e.g. on islands, off-grid and in some countries) a lower-cost renewable solution almost always exists today". As of 2012, renewable power generation technologies accounted for around half of all new power generation capacity additions globally. In 2011, additions included 41 gigawatt (GW) of new wind power capacity, 30 GW of PV, 25 GW of hydro-electricity, 6 GW of biomass, 0.5 GW of CSP, and 0.1 GW of geothermal power.
What is the answer to this question: What are now often the most economic solution for new generating capacity?

So... Renewable technologies

Here is a question about this article: It was not unusual for electric recordings to be played back on acoustic phonographs. The Victor Orthophonic phonograph was a prime example where such playback was expected. In the Orthophonic, which benefited from telephone research, the mechanical pickup head was redesigned with lower resonance than the traditional mica type. Also, a folded horn with an exponential taper was constructed inside the cabinet to provide better impedance matching to the air. As a result, playback of an Orthophonic record sounded like it was coming from a radio.
What is the answer to this question: Was it common to hear electric recordings on phonographs?

So...
not unusual
