[EX Q]: Question: Which countries made up the group that invaded Yugoslavia? Passage:On 6 April 1941, Yugoslavia was invaded from all sides by the Axis powers, led by German forces. Stojanović was assigned as a physician to an infantry battalion based in Banja Luka. For several days after the invasion this battalion moved toward Dalmatia, before it completely disintegrated without fighting the enemy, and Stojanović returned to Prijedor. The Royal Yugoslav Army capitulated on 17 April, and the Axis powers proceeded to dismember Yugoslavia. Almost all of modern-day Croatia, all of modern-day Bosnia-Herzegovina, and parts of modern-day Serbia were combined into a puppet state called the Independent State of Croatia (, NDH). It was an "Italian-German quasi-protectorate", which was controlled by the fascist Ustaše led by Ante Pavelić. One of its policies was to eliminate the ethnic Serb population of the NDH through mass killings, expulsions and forced assimilation, and many Serbs fled from the NDH to the German-occupied territory of Serbia.

[EX Q]: Question: Who is the current head of the government agency other than the Department of Justice that Westinghouse complained about NBC's extortion? Passage:Channel 4 was in danger of losing its NBC affiliation when Westinghouse balked at NBC's initial offer to trade sister stations KYW radio and WPTZ television (now KYW-TV) in Philadelphia in exchange for WTAM-AM-FM and WNBK television (now WKYC-TV) in Cleveland. In response, NBC threatened to pull its programming from both WBZ-TV and WPTZ unless Westinghouse agreed to the trade. The swap was made in February 1956, but Westinghouse immediately complained to the Federal Communications Commission (FCC) and the U.S. Department of Justice about NBC's extortion. The threat reemerged in 1960 after NBC announced it would swap the Philadelphia stations in exchange for a competing Boston outlet, then-CBS affiliate WNAC-TV (channel 7) and its sister radio stations, from RKO General. Approval of the RKO-NBC deal would have potentially made WBZ-TV an ABC affiliate, completing a three-way swap of network affiliations in Boston. However, in 1964, the FCC nullified the NBC-RKO trade and ordered the NBC-Westinghouse swap reversed without NBC realizing any profit on the deal. WBZ-TV retained its NBC affiliation as a result of the canceled sale.
