Teacher: Now, understand the problem? Solve this instance: Question: Who were the members of Thailand national  football team when their captain, Kawin Thamsatchanan, signed with OH Leuven? Passage 1:In the spring of 1868 he made his first trip to the edge of Central Asia, traveling with a Russian merchant, Vasilii Alekseich, by steamboat down the Volga to Samara, then by carriage to Orenburg, which at the time was the base for Russian military operations The Russians had occupied the Khanate of Bukhara in 1866 and were advancing toward Samarkand. In 1868, Schuyler was a guest of Tolstoi for a week at his estate at Yasnaya Polyana, at the time when Tolstoi was finishing War and Peace. He helped Tolstoi rearrange his library, and went hunting with him. Tolstoi, who was interested in public education in the United States, asked Schuyler for copies of American primers and school textbooks. Schuyler received Tolstoi's permission to translate his novel The Cossacks into English. In 1869, the new Administration of President Ulysses Grant removed Schuyler from his post in Moscow and replaced him with a political appointee. Schuyler was able to obtain a post as consul to the Russian port of Reval (now Tallinn). In November, 1869, President Grant appointed a new Minister to Russia, Andrew Curtin, a former Governor of Pennsylvania who knew nothing of Russia. Curtin was impressed by Schuyler and appointed him as the secretary of the American legation in St. Petersburg, a post which Schuyler held until 1876.
 Passage 2:Gillekens made his debut for OH Leuven in the 2014–15 Belgian Cup in the sixth round match against Kortrijk, a 1-3 loss, although that season he was part of the reserves and only fourth goalkeeper behind Logan Bailly, Yves Lenaerts and Senne Vits. Later that season he also played one match in the 2014–15 Belgian Second Division against Mons. Although Gillekens was promoted to third keeper for the 2015–16 season, he did not play a single match that season. Following the relegation from the 2015–16 Belgian Pro League, first goalkeeper Rudy Riou was released while second goalkeeper Yves Lenaerts had already signed for ASV Geel. As such, Gillekens was promoted to first goalkeeper for the 2016–17 season in the Belgian First Division B. During the winter 2017–18 transfer window OH Leuven signed Kawin Thamsatchanan, captain of the Thailand national football team and soon thereafter Gillekens was demoted to reserve goalkeeper. Following Thamsatchanan's injury during the 2018–19 season, Gillekens again became first goalkeeper for a few matches before then being surpassed by Laurent Henkinet. Towards the end of the season, Gillekens was even demoted to third goalkeeper with Thamsatchanan now taking his place on the bench and after the final match of the season it became clear that Gillekens would not be signing a new deal at OH Leuven.
 Passage 3:Commelina hockii is an herbaceous plant in the dayflower family found primarily in Central Africa, from southwestern Tanzania in the east, west through the Democratic Republic of the Congo and Zambia, and possibly extending further west to Angola. The species' distinctive features include its long, tapering spathes with unfused margins, its white flowers, and its many-flowered lower cymes. It can be found in grasslands and Brachystegia-dominated woodland. It is fairly unusual among Commelina species in having variation in the color of the antherodes (i.e. non-functional anthers), with some individuals having entirely yellow antherodes, while others contain a dark spot in the center. Also, it is one of the only Commelina species known to leave a papery residue of dried fluid inside its spathes; normally only fused-spathe species are known to produce this substance. Only one specimen from Angola resembles this species, but it has blue flowers, suggesting it may be a poorly understood and as-yet undescribed separate species. Commelina hockii is probably closely related to Commelina kituloensis, which shares a similar fruit type, the same tufted perennial habit, similar large spathes with dried fluid substance, and equally numerously flowered inflorescences. That species differs in having purplish flowers, hairy leaves, shorter spathes, and a preference for high altitude grassland.
