Problem: Alps:

The Alps (/lps/; Italian: Alpi [alpi]; French: Alpes [alp]; German: Alpen [alpm]; Slovene: Alpe [alp]) are the highest and most extensive mountain range system that lies entirely in Europe, stretching approximately 1,200 kilometres (750 mi) across eight Alpine countries: Austria, France, Germany, Italy, Liechtenstein, Monaco, Slovenia, and Switzerland. The Caucasus Mountains are higher, and the Urals longer, but both lie partly in Asia. The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrusting and folding into high mountain peaks such as Mont Blanc and the Matterhorn. Mont Blanc spans the FrenchItalian border, and at 4,810 m (15,781 ft) is the highest mountain in the Alps. The Alpine region area contains about a hundred peaks higher than 4,000 m (13,123 ft), known as the "four-thousanders".

How many kilometres do the Alps stretch?

A: 1,200 kilometres

Problem: Lighting:

Color temperature for white light sources also affects their use for certain applications. The color temperature of a white light source is the temperature in Kelvin of a theoretical black body emitter that most closely matches the spectral characteristics of the lamp. An incandescent bulb has a color temperature around 2800 to 3000 Kelvin; daylight is around 6400 Kelvin. Lower color temperature lamps have relatively more energy in the yellow and red part of the visible spectrum, while high color temperatures correspond to lamps with more of a blue-white appearance. For critical inspection or color matching tasks, or for retail displays of food and clothing, the color temperature of the lamps will be selected for the best overall lighting effect.

A lamp with more energy in the yellow and red spectrum are known to be?
---
A: Lower color temperature

Problem: Royal assent:

In Commonwealth realms other than the UK, royal assent is granted or withheld either by the realm's sovereign or, more frequently, by the representative of the sovereign, the governor-general. In federated realms, assent in each state, province, or territory is granted or withheld by the representatives of the sovereign. In Australia, this is the governors of the states, administrators of the territories, or the governor-general in the Australian Capital Territory. For Canada, this is the lieutenant governors of the provinces. A lieutenant governor may defer assent to the governor general, and the governor general may defer assent to federal bills to the sovereign.

The realm's sovereign grants or withholds regal what?
---
A: unanswerable

Problem: Serbo-Croatian:

Throughout the history of the South Slavs, the vernacular, literary, and written languages (e.g. Chakavian, Kajkavian, Shtokavian) of the various regions and ethnicities developed and diverged independently. Prior to the 19th century, they were collectively called "Illyric", "Slavic", "Slavonian", "Bosnian", "Dalmatian", "Serbian" or "Croatian". As such, the term Serbo-Croatian was first used by Jacob Grimm in 1824, popularized by the Vienna philologist Jernej Kopitar in the following decades, and accepted by Croatian Zagreb grammarians in 1854 and 1859. At that time, Serb and Croat lands were still part of the Ottoman and Austrian Empires. Officially, the language was called variously Serbo-Croat, Croato-Serbian, Serbian and Croatian, Croatian and Serbian, Serbian or Croatian, Croatian or Serbian. Unofficially, Serbs and Croats typically called the language "Serbian" or "Croatian", respectively, without implying a distinction between the two, and again in independent Bosnia and Herzegovina, "Bosnian", "Croatian", and "Serbian" were considered to be three names of a single official language. Croatian linguist Dalibor Brozovic advocated the term Serbo-Croatian as late as 1988, claiming that in an analogy with Indo-European, Serbo-Croatian does not only name the two components of the same language, but simply charts the limits of the region in which it is spoken and includes everything between the limits ('Bosnian' and 'Montenegrin'). Today, use of the term "Serbo-Croatian" is controversial due to the prejudice that nation and language must match. It is still used for lack of a succinct alternative, though alternative names have been used, such as Bosnian/Croatian/Serbian (BCS), which is often seen in political contexts such as the Hague War Crimes tribunal.

Who first used the term Serbo-Croatian in 1824?

A:
Jacob Grimm
