Around 1200 BC, the Dorians, another Greek-speaking people, followed from Epirus. Traditionally, historians have believed that the Dorian invasion caused the collapse of the Mycenaean civilization, but it is likely the main attack was made by seafaring raiders (sea peoples) who sailed into the eastern Mediterranean around 1180 BC. The Dorian invasion was followed by a poorly attested period of migrations, appropriately called the Greek Dark Ages, but by 800 BC the landscape of Archaic and Classical Greece was discernible.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When didn't these groups make the migration ?
Ah, so.. unanswerable

Alaska's economy depends heavily on increasingly expensive diesel fuel for heating, transportation, electric power and light. Though wind and hydroelectric power are abundant and underdeveloped, proposals for statewide energy systems (e.g. with special low-cost electric interties) were judged uneconomical (at the time of the report, 2001) due to low (less than 50¢/gal) fuel prices, long distances and low population. The cost of a gallon of gas in urban Alaska today is usually 30–60¢ higher than the national average; prices in rural areas are generally significantly higher but vary widely depending on transportation costs, seasonal usage peaks, nearby petroleum development infrastructure and many other factors.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What does Alaska's economy not rely on?
Ah, so.. unanswerable

Growing out of the Somali people's rich storytelling tradition, the first few feature-length Somali films and cinematic festivals emerged in the early 1960s, immediately after independence. Following the creation of the Somali Film Agency (SFA) regulatory body in 1975, the local film scene began to expand rapidly. The Somali filmmaker Ali Said Hassan concurrently served as the SFA's representative in Rome. In the 1970s and early 1980s, popular musicals known as riwaayado were the main driving force behind the Somali movie industry. Epic and period films as well as international co-productions followed suit, facilitated by the proliferation of video technology and national television networks. Said Salah Ahmed during this period directed his first feature film, The Somali Darwish (The Somalia Dervishes), devoted to the Dervish State. In the 1990s and 2000s, a new wave of more entertainment-oriented movies emerged. Referred to as Somaliwood, this upstart, youth-based cinematic movement has energized the Somali film industry and in the process introduced innovative storylines, marketing strategies and production techniques. The young directors Abdisalam Aato of Olol Films and Abdi Malik Isak are at the forefront of this quiet revolution.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In what year was the SFA founded?
Ah, so..
1975
