Problem: Please answer a question about the following article about Renewable energy commercialization:
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 most economic solution for new grid-connected capacity in areas with good resources?
A: Renewable energy
Problem: Please answer a question about the following article about Portugal:
In 1348 and 1349 Portugal, like the rest of Europe, was devastated by the Black Death. In 1373, Portugal made an alliance with England, which is the longest-standing alliance in the world. This alliance served both nations' interests throughout history and is regarded by many as the predecessor to NATO. Over time this went way beyond geo-political and military cooperation (protecting both nations' interests in Africa, the Americas and Asia against French, Spanish and Dutch rivals) and maintained strong trade and cultural ties between the two old European allies. Particularly in the Oporto region, there is visible English influence to this day.
The Portugal-English alliance served as the predecessor to what?
A: NATO
Problem: Please answer a question about the following article about Umayyad Caliphate:
The Umayyad caliphate was marked both by territorial expansion and by the administrative and cultural problems that such expansion created. Despite some notable exceptions, the Umayyads tended to favor the rights of the old Arab families, and in particular their own, over those of newly converted Muslims (mawali). Therefore, they held to a less universalist conception of Islam than did many of their rivals. As G.R. Hawting has written, "Islam was in fact regarded as the property of the conquering aristocracy."
What sorts of families did the Umayyads show favor to?
A: old Arab
Problem: Please answer a question about the following article about Josip Broz Tito:
Yugoslavia organized the Yugoslav People's Army (Jugoslavenska narodna armija, or JNA) from the Partisan movement and became the fourth strongest army in Europe at the time. The State Security Administration (Uprava državne bezbednosti/sigurnosti/varnosti, UDBA) was also formed as the new secret police, along with a security agency, the Department of People's Security (Organ Zaštite Naroda (Armije), OZNA). Yugoslav intelligence was charged with imprisoning and bringing to trial large numbers of Nazi collaborators; controversially, this included Catholic clergymen due to the widespread involvement of Croatian Catholic clergy with the Ustaša regime. Draža Mihailović was found guilty of collaboration, high treason and war crimes and was subsequently executed by firing squad in July 1946.
What was formed as the new secret police?
A:
The State Security Administration
