In 2006, a study by Behar et al., based on what was at that time high-resolution analysis of haplogroup K (mtDNA), suggested that about 40% of the current Ashkenazi population is descended matrilineally from just four women, or "founder lineages", that were "likely from a Hebrew/Levantine mtDNA pool" originating in the Middle East in the 1st and 2nd centuries CE. Additionally, Behar et al. suggested that the rest of Ashkenazi mtDNA is originated from ~150 women, and that most of those were also likely of Middle Eastern origin. In reference specifically to Haplogroup K, they suggested that although it is common throughout western Eurasia, "the observed global pattern of distribution renders very unlikely the possibility that the four aforementioned founder lineages entered the Ashkenazi mtDNA pool via gene flow from a European host population".
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): The founder lineages were likely from what type of mtDNA pool?
Ah, so.. Hebrew/Levantine

In spring 1987, a protest movement arose against new phosphate mines in Estonia. Signatures were collected in Tartu, and students assembled in the university's main hall to express lack of confidence in the government. At a demonstration on May 1, 1987, young people showed up with banners and slogans despite an official ban. On August 15, 1987, former political prisoners formed the MRP-AEG group (Estonians for the Public Disclosure of the Molotov-Ribbentrop Pact), which was headed by Tiit Madisson. In September 1987, the Edasi newspaper published a proposal by Edgar Savisaar, Siim Kallas, Tiit Made, and Mikk Titma calling for Estonia's transition to autonomy. Initially geared toward economic independence, then toward a certain amount of political autonomy, the project, Isemajandav Eesti ("A Self-Managing Estonia") became known according to its Estonian acronym, IME, which means "miracle". On October 21, a demonstration dedicated to those who gave their lives in the 19181920 Estonian War of Independence took place in Voru, which culminated in a conflict with the militia. For the first time in years, the blue, black, and white national tricolor was publicly displayed.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What was being protested in Estonia?
Ah, so.. new phosphate mines

Carriers have evolved since their inception in the early twentieth century from wooden vessels used to deploy balloons to nuclear-powered warships that carry dozens of aircraft, including fighter jets and helicopters. As of 3 March 2016, there are thirty-seven active aircraft carriers in the world within twelve navies. The United States Navy has 10 large nuclear-powered carriers (known as supercarriers, carrying up to 90 aircraft each), the largest carriers in the world; the total deckspace is over twice that of all other nations' combined. As well as the supercarrier fleet, the US Navy has nine amphibious assault ships used primarily for helicopters (sometimes called helicopter carriers); these can also carry up to 25 fighter jets, and in some cases, are as large as some other nations' fixed-wing carriers.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): As of 3/3/2016, how many active aircraft carriers are there worldwide?
Ah, so..
thirty-seven
