[EX Q]: 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?
[EX A]: Belgrade

[EX Q]: Passage: The first PCBs used through-hole technology, mounting electronic components by leads inserted through holes on one side of the board and soldered onto copper traces on the other side. Boards may be single-sided, with an unplated component side, or more compact double-sided boards, with components soldered on both sides. Horizontal installation of through-hole parts with two axial leads (such as resistors, capacitors, and diodes) is done by bending the leads 90 degrees in the same direction, inserting the part in the board (often bending leads located on the back of the board in opposite directions to improve the part's mechanical strength), soldering the leads, and trimming off the ends. Leads may be soldered either manually or by a wave soldering machine. Question: For boards with two sides, to what angle are leads bent to in order to install them horizontally?
[EX A]: 90 degrees

Meanwhile, Amtrak's Downeaster service to Maine originates at North Station, despite the current lack of a dedicated passenger rail link between the two railhubs, other than the "T" subway lines. Question: Where do Amtrack's Northeast corridor and Chicago lines end?
