question:
Passage: On 7 March 1945, the provisional government of the Democratic Federal Yugoslavia (Demokratska Federativna Jugoslavija, DFY) was assembled in Belgrade by Josip Broz Tito, while the provisional name allowed for either a republic or monarchy. This government was headed by Tito as provisional Yugoslav Prime Minister and included representatives from the royalist government-in-exile, among others Ivan Šubašić. In accordance with the agreement between resistance leaders and the government-in-exile, post-war elections were held to determine the form of government. In November 1945, Tito's pro-republican People's Front, led by the Communist Party of Yugoslavia, won the elections with an overwhelming majority, the vote having been boycotted by monarchists. During the period, Tito evidently enjoyed massive popular support due to being generally viewed by the populace as the liberator of Yugoslavia. The Yugoslav administration in the immediate post-war period managed to unite a country that had been severely affected by ultra-nationalist upheavals and war devastation, while successfully suppressing the nationalist sentiments of the various nations in favor of tolerance, and the common Yugoslav goal. After the overwhelming electoral victory, Tito was confirmed as the Prime Minister and the Minister of Foreign Affairs of the DFY. The country was soon renamed the Federal People's Republic of Yugoslavia (FPRY) (later finally renamed into Socialist Federal Republic of Yugoslavia, SFRY). On 29 November 1945, King Peter II was formally deposed by the Yugoslav Constituent Assembly. The Assembly drafted a new republican constitution soon afterwards. Question: Where was the provisional government of the Democratic Federal Yugoslavia assembled?
answer:
Belgrade


question:
Passage: Efforts to identify the origins of Ashkenazi Jews through DNA analysis began in the 1990s. Currently, there are three types of genetic origin testing, autosomal DNA (atDNA), mitochondrial DNA (mtDNA), and Y-chromosomal DNA (Y-DNA). Autosomal DNA is a mixture from an individual's entire ancestry, Y-DNA shows a male's lineage only along his strict-paternal line, mtDNA shows any person's lineage only along the strict-maternal line. Genome-wide association studies have also been employed to yield findings relevant to genetic origins. Question: How many types of genetic origin testing currently exist?
answer:
three types of genetic origin testing


question:
Passage: Of all the questions on the scale, Sell considered those assessing sexual attraction to be the most important as sexual attraction is a better reflection of the concept of sexual orientation which he defined as "extent of sexual attractions toward members of the other, same, both sexes or neither" than either sexual identity or sexual behavior. Identity and behavior are measured as supplemental information because they are both closely tied to sexual attraction and sexual orientation. Major criticisms of the SASO have not been established, but a concern is that the reliability and validity remains largely unexamined. Question: What is a huge concern for SASO?
answer:

the reliability and validity remains largely unexamined.
