Problem: Alaska:

Most food in Alaska is transported into the state from "Outside", and shipping costs make food in the cities relatively expensive. In rural areas, subsistence hunting and gathering is an essential activity because imported food is prohibitively expensive. Though most small towns and villages in Alaska lie along the coastline, the cost of importing food to remote villages can be high, because of the terrain and difficult road conditions, which change dramatically, due to varying climate and precipitation changes. The cost of transport can reach as high as 50 per pound ($1.10/kg) or more in some remote areas, during the most difficult times, if these locations can be reached at all during such inclement weather and terrain conditions. The cost of delivering a 1 US gallon (3.8 L) of milk is about $3.50 in many villages where per capita income can be $20,000 or less. Fuel cost per gallon is routinely 2030 higher than the continental United States average, with only Hawaii having higher prices.

How much does it cost to transport a gallon of milk in some rural areas of Alaska?

A: $3.50

Problem: As a teenager, he was greatly troubled by the Metaphysics of Aristotle, which he could not understand until he read al-Farabi's commentary on the work. For the next year and a half, he studied philosophy, in which he encountered greater obstacles. In such moments of baffled inquiry, he would leave his books, perform the requisite ablutions, then go to the mosque, and continue in prayer till light broke on his difficulties. Deep into the night, he would continue his studies, and even in his dreams problems would pursue him and work out their solution. Forty times, it is said, he read through the Metaphysics of Aristotle, till the words were imprinted on his memory; but their meaning was hopelessly obscure, until one day they found illumination, from the little commentary by Farabi, which he bought at a bookstall for the small sum of three dirhams. So great was his joy at the discovery, made with the help of a work from which he had expected only mystery, that he hastened to return thanks to God, and bestowed alms upon the poor.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The first newspaper in Namibia was the German-language Windhoeker Anzeiger, founded 1898. Radio was introduced in 1969, TV in 1981. During German rule, the newspapers mainly reflected the living reality and the view of the white German-speaking minority. The black majority was ignored or depicted as a threat. During South African rule, the white bias continued, with mentionable influence of the Pretoria government on the "South West African" media system. Independent newspapers were seen as a menace to the existing order, critical journalists threatened.
When was radio introduced in Namibia?
A: 1969

Context and question: The sky is usually clear above the desert and the sunshine duration is extremely high everywhere in the Sahara. Most of the desert enjoys more than 3,600 h of bright sunshine annually or over 82% of the time and a wide area in the eastern part experiences in excess of 4,000 h of bright sunshine a year or over 91% of the time, and the highest values are very close to the theoretical maximum value. A value of 4,300 h or 98% of the time would be recorded in Upper Egypt (Aswan, Luxor) and in the Nubian Desert (Wadi Halfa). The annual average direct solar irradiation is around 2,800 kWh/(m2 year) in the Great Desert. The Sahara has a huge potential for solar energy production. The constantly high position of the sun, the extremely low relative humidity, the lack of vegetation and rainfall make the Great Desert the hottest continuously large area worldwide and certainly the hottest place on Earth during summertime in some spots. The average high temperature exceeds 38 C (100.4 F) - 40 C (104 F) during the hottest month nearly everywhere in the desert except at very high mountainous areas. The highest officially recorded average high temperature was 47 C (116.6 F) in a remote desert town in the Algerian Desert called Bou Bernous with an elevation of 378 meters above sea level. It's the world's highest recorded average high temperature and only Death Valley, California rivals it. Other hot spots in Algeria such as Adrar, Timimoun, In Salah, Ouallene, Aoulef, Reggane with an elevation between 200 and 400 meters above sea level get slightly lower summer average highs around 46 C (114.8 F) during the hottest months of the year. Salah, well known in Algeria for its extreme heat, has an average high temperature of 43.8 C (110.8 F), 46.4 C (115.5 F), 45.5 (113.9 F). Furthermore, 41.9 C (107.4 F) in June, July, August and September. In fact, there are even hotter spots in the Sahara, but they are located in extremely remote areas, especially in the Azalai, lying in northern Mali. The major part of the desert experiences around 3 5 months when the average high strictly exceeds 40 C (104 F). The southern central part of the desert experiences up to 6 7 months when the average high temperature strictly exceeds 40 C (104 F) which shows the constancy and the length of the really hot season in the Sahara. Some examples of this are Bilma, Niger and Faya-Largeau, Chad. The annual average daily temperature exceeds 20 C (68 F) everywhere and can approach 30 C (86 F) in the hottest regions year-round. However, most of the desert has a value in excess of 25 C (77 F). The sand and ground temperatures are even more extreme. During daytime, the sand temperature is extremely high as it can easily reach 80 C (176 F) or more. A sand temperature of 83.5 C (182.3 F) has been recorded in Port Sudan. Ground temperatures of 72 C (161.6 F) have been recorded in the Adrar of Mauritania and a value of 75 C (167 F) has been measured in Borkou, northern Chad. Due to lack of cloud cover and very low humidity, the desert usually features high diurnal temperature variations between days and nights. However, it's a myth that the nights are cold after extremely hot days in the Sahara. The average diurnal temperature range is typically between 13 C (55.4 F) and 20 C (68 F). The lowest values are found along the coastal regions due to high humidity and are often even lower than 10 C (50 F), while the highest values are found in inland desert areas where the humidity is the lowest, mainly in the southern Sahara. Still, it's true that winter nights can be cold as it can drop to the freezing point and even below, especially in high-elevation areas.
How much solar energy does the Sahara produce per year?
Answer: unanswerable
