Input: Read this: Congo's democratic progress was derailed in 1997 when Lissouba and Sassou started to fight for power in the civil war. As presidential elections scheduled for July 1997 approached, tensions between the Lissouba and Sassou camps mounted. On June 5, President Lissouba's government forces surrounded Sassou's compound in Brazzaville and Sassou ordered members of his private militia (known as "Cobras") to resist. Thus began a four-month conflict that destroyed or damaged much of Brazzaville and caused tens of thousands of civilian deaths. In early October, the Angolan socialist regime began an invasion of Congo to install Sassou in power. In mid-October, the Lissouba government fell. Soon thereafter, Sassou declared himself president.
Question: What were members of Lissouba's militia called?

Output: unanswerable

QUES: Valencia is a bilingual city: Valencian and Spanish are the two official languages. Spanish is official in all of Spain, whereas Valencian is official in the Valencian Country, as well as in Catalonia and the Balearic Islands, where it receives the name of Catalan. Despite the differentiated denomination, the distinct dialectal traits and political tension between Catalonia and the Valencian Country, Catalan and Valencian are mutually intelligible and are considered two varieties of the same language.
Valencian has been historically repressed in favour of Spanish. The effects have been more noticeable in the city proper, whereas the language has remained active in the rural and metropolitan areas. After the Castille-Aragon unification, a Spanish-speaking elite established itself in the city. In more recent history, the establishment of Franco's military and administrative apparatus in Valencia further excluded Valencian from public life. Valencian recovered its official status, prestige and use in education after the transition to democracy in 1978. However, due to industrialisation in recent decades, Valencia has attracted immigration from other regions in Spain, and hence there is also a demographic factor for its declining social use. Due to a combination of these reasons, Valencia has become the bastion of anti-Catalan blaverism, which celebrates Valencian as merely folkloric, but rejects the existing standard which was adapted from Catalan orthography.
Spanish is currently the predominant language in the city proper but, thanks to the education system, most Valencians have basic knowledge of both Spanish and Valencian, and either can be used in the city. Valencia is therefore the second biggest Catalan-speaking city after Barcelona. Institutional buildings and streets are named in Valencian. The city is also home to many pro-Valencian political and civil organisations. Furthermore, education entirely in Valencian is offered in more than 70 state-owned schools in the city, as well as by the University of Valencia across all disciplines.

What language is official in Valencia besides Valencian?
What is the answer?
ANS: Spanish

QUES: Early MPEG Layer III encoders used what is now called Constant Bit Rate (CBR). The software was only able to use a uniform bitrate on all frames in an MP3 file. Later more sophisticated MP3 encoders were able to use the bit reservoir to target an average bit rate selecting the encoding rate for each frame based on the complexity of the sound in that portion of the recording.
What did more sophisticated MP3 encoders use to target an average bit rate?

ANS: bit reservoir

On 15 September 1940, known as the Battle of Britain Day, an RAF pilot, Ray Holmes of No. 504 Squadron RAF rammed a German bomber he believed was going to bomb the Palace. Holmes had run out of ammunition and made the quick decision to ram it. Holmes bailed out. Both aircraft crashed. In fact the Dornier Do 17 bomber was empty. It had already been damaged, two of its crew had been killed and the remainder bailed out. Its pilot, Feldwebel Robert Zehbe, landed, only to die later of wounds suffered during the attack. During the Dornier's descent, it somehow unloaded its bombs, one of which hit the Palace. It then crashed into the forecourt of London Victoria station. The bomber's engine was later exhibited at the Imperial War Museum in London. The British pilot became a King's Messenger after the war, and died at the age of 90 in 2005.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What did Ray Holmes believe the German pilot was targeting?
Ah, so.. the Palace

Question: Egypt has a developed energy market based on coal, oil, natural gas, and hydro power. Substantial coal deposits in the northeast Sinai are mined at the rate of about 600,000 tonnes (590,000 long tons; 660,000 short tons) per year. Oil and gas are produced in the western desert regions, the Gulf of Suez, and the Nile Delta. Egypt has huge reserves of gas, estimated at 2,180 cubic kilometres (520 cu mi), and LNG up to 2012 exported to many countries. In 2013, the Egyptian General Petroleum Co (EGPC) said the country will cut exports of natural gas and tell major industries to slow output this summer to avoid an energy crisis and stave off political unrest, Reuters has reported. Egypt is counting on top liquid natural gas (LNG) exporter Qatar to obtain additional gas volumes in summer, while encouraging factories to plan their annual maintenance for those months of peak demand, said EGPC chairman, Tarek El Barkatawy. Egypt produces its own energy, but has been a net oil importer since 2008 and is rapidly becoming a net importer of natural gas.
Try to answer this question if possible: How much coal is mine yearly in northeast Sinai?
Answer: 600,000 tonnes

Question: Punjab during Mahabharata times was known as Panchanada. Punjab was part of the Indus Valley Civilization, more than 4000 years ago. The main site in Punjab was the city of Harrapa. The Indus Valley Civilization spanned much of what is today Pakistan and eventually evolved into the Indo-Aryan civilisation. The Vedic civilisation flourished along the length of the Indus River. This civilisation shaped subsequent cultures in South Asia and Afghanistan. Although the archaeological site at Harappa was partially damaged in 1857 when engineers constructing the Lahore-Multan railroad used brick from the Harappa ruins for track ballast, an abundance of artefacts have nevertheless been found. Punjab was part of the great ancient empires including the Gandhara Mahajanapadas, Achaemenids, Macedonians, Mauryas, Kushans, Guptas, and Hindu Shahi. It also comprised the Gujar empire for a period of time, otherwise known as the Gurjara-Pratihara empire. Agriculture flourished and trading cities (such as Multan and Lahore) grew in wealth.
