Problem: Eritrea:

Eritrea is a multilingual country. The nation has no official language, as the Constitution establishes the "equality of all Eritrean languages". However, Tigrinya serves as the de facto language of national identity. With 2,540,000 total speakers of a population of 5,254,000 in 2006, Tigrinya is the most widely spoken language, particularly in the southern and central parts of Eritrea. Modern Standard Arabic and English serve as de facto working languages, with the latter used in university education and many technical fields. Italian, the former colonial language, is widely used in commerce and is taught as a second language in schools, with a few elderly monolinguals.

A: The nation has no official language


Problem: Another work from Ancient Greece that made an early impact on botany is De Materia Medica, a five-volume encyclopedia about herbal medicine written in the middle of the first century by Greek physician and pharmacologist Pedanius Dioscorides. De Materia Medica was widely read for more than 1,500 years. Important contributions from the medieval Muslim world include Ibn Wahshiyya's Nabatean Agriculture, Abū Ḥanīfa Dīnawarī's (828–896) the Book of Plants, and Ibn Bassal's The Classification of Soils. In the early 13th century, Abu al-Abbas al-Nabati, and Ibn al-Baitar (d. 1248) wrote on botany in a systematic and scientific manner.
Besides the Greeks, what other culture contributed to the study of botany?
---
Answer: medieval Muslim world


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
As a consequence, there was a crisis in international confidence in Greece's ability to repay its sovereign debt, as reflected by the rise of the country's borrowing rates (although their slow rise – the 10-year government bond yield only exceeded 7% in April 2010 – coinciding with a large number of negative articles, has led to arguments about the role of international news media in the evolution of the crisis). In order to avert a default (as high borrowing rates effectively prohibited access to the markets), in May 2010 the other Eurozone countries, and the IMF, agreed to a "rescue package" which involved giving Greece an immediate €45 billion in bail-out loans, with more funds to follow, totaling €110 billion. In order to secure the funding, Greece was required to adopt harsh austerity measures to bring its deficit under control. Their implementation will be monitored and evaluated by the European Commission, the European Central Bank and the IMF.
How much money did the IMF and other Eurozone countries agree to steal from Greece in 2010?
A: unanswerable


Context and question: The format also became quite popular in Hong Kong during the 1990s before the introduction of VCDs and DVD; although people rarely bought the discs (because each LD was priced around USD100), high rental activity helped the video rental business in the city grow larger than it had ever been previously. Due to integration with the Japanese export market, NTSC LaserDiscs were used in the Hong Kong market, in contrast to the PAL standard used for broadcast (This anomaly also exists for DVD). This created a market for multi-system TVs and multi-system VCRs which could display or play both PAL and NTSC materials in addition to SECAM materials (which were never popular in Hong Kong). Some LD players could convert NTSC signals to PAL so that most TVs used in Hong Kong could display the LD materials.
How much did a LD cost in Hong Kong in the 1990s?
Answer: USD100


Question: Gaddafi briefly studied History at the University of Libya in Benghazi, before dropping out to join the military. Despite his police record, in 1963 he began training at the Royal Military Academy, Benghazi, alongside several like-minded friends from Misrata. The armed forces offered the only opportunity for upward social mobility for underprivileged Libyans, and Gaddafi recognised it as a potential instrument of political change. Under Idris, Libya's armed forces were trained by the British military; this angered Gaddafi, who viewed the British as imperialists, and accordingly he refused to learn English and was rude to the British officers, ultimately failing his exams. British trainers reported him for insubordination and abusive behaviour, stating their suspicion that he was involved in the assassination of the military academy's commander in 1963. Such reports were ignored and Gaddafi quickly progressed through the course.
Is there an answer to this question: During his time in college, what did Gaddafi study?

Answer: History


50 Hz systems support three scanning rates: 50i, 25p and 50p. 60 Hz systems support a much wider set of frame rates: 59.94i, 60i, 23.976p, 24p, 29.97p, 30p, 59.94p and 60p. In the days of standard definition television, the fractional rates were often rounded up to whole numbers, e.g. 23.976p was often called 24p, or 59.94i was often called 60i. 60 Hz high definition television supports both fractional and slightly different integer rates, therefore strict usage of notation is required to avoid ambiguity. Nevertheless, 29.97i/59.94i is almost universally called 60i, likewise 23.976p is called 24p.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What three scanning rates do 50 Hz systems support?
Ah, so..
50i, 25p and 50p
