Passage: A rejuvenated Nick Foles got his starting job back after being benched in favor of Case Keenum, who suffered a concussion after last week's loss in Baltimore. However, Foles' return was marred as he struggled to find open receivers and was picked off three times by the Bengals ranked defense. He also took hits throughout the game and he was sacked a few times. The only Rams score was a 5-yard run by Tavon Austin on a reverse play in the second quarter. St. Louis' defense was not a factor all game as they struggled to stop the high-powered Bengals offense led by quarterback Andy Dalton, and receivers A. J. Green, and Tyler Eifert, (the latter left the game with a stinger) who is leading the league in touchdown catches. With the loss, the Rams extended their losing streak to 4 games, making their record 4-7.
Question: Who did Keenum suffer his concussion playing against?

Passage: In 1945 the border between Poland and Czechoslovakia was set at the 1920 line. Polish troops then occupied northern Orava and Spiš on 17 July 1945. There were armed clashes and fatalities in some villages over the following two years. Slovaks from the Polish part of Spiš settled mainly in the newly created industrial town of Svit near Poprad, Kežmarok, Poprad, and in depopulated German villages  near Kežmarok. Slovaks from the Polish part of Orava settled mainly in Czech Silesia, and in depopulated German villages in the Czech lands . On 10 March 1947 a treaty guaranteeing basic rights for Slovaks in Poland was signed between Czechoslovakia and Poland. As a result, 41 Slovak basic schools and 1 high school were opened in Poland. Most of these however were shut down in the early sixties because of lack of Slovakian teachers. On June 13, 1958, in Warsaw, the two countries signed a treaty confirming the border at the line of January 1, 1938 , and since then there have been no conflicts regarding this matter. In March 1975 Czechoslovakia and Poland modified their border along the Dunajec to permit Poland to construct a dam in the Czorsztyn region, southeast of Kraków.

Passage: From 1623 to 1624 the Dutch had been at war over the Pescadores, and in 1633 clashed with a fleet led by Zheng Zhilong in the Battle of Liaoluo Bay, ending in another Dutch defeat. By 1632 the Dutch had established a post on a peninsula named Tayoan , which was separated from the main part of Formosa by a shallow lagoon historically referred to as the Taikang inland sea . The Dutch fortifications consisted of two forts along the bay: the first and main fortification was the multiple-walled Fort Zeelandia, situated at the entrance to the bay, while the second was the smaller Fort Provintia, a walled administrative office. Frederick Coyett, the governor of Taiwan for the Dutch East India Company, was stationed in Fort Zeelandia with 1,800 men, while his subordinate, Valentyn, was in charge of Fort Provintia and its garrison of 500 men. In 1659, after an unsuccessful attempt to capture Nanjing, Koxinga, son of Zheng Zhilong and leader of the Ming loyalist remnants, felt that the Qing Empire had consolidated their position in China sufficiently, while his troops needed more supplies and manpower. He began searching for a suitable location as his base of operations, and soon a Chinese man named He Bin , who was working for the Dutch East India Company in Formosa , fled to Koxinga's base in Xiamen and provided him with a map of Taiwan.
Question: Which forts belonged to the Dutch?
