In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Question: Who won the World Cup where the Costa Rican team had a prominent performance? Passage:Since the late 1980s, the team has continuously been visible as a solidly competitive side, with a prominent performance in the 1990 FIFA World Cup in Italy, making it to the knockout stage in their debut after finishing second in their group during the first phase, below Brazil. They also managed to qualify for the 2002 and 2006 FIFA World Cups. In 2014, Costa Rica made their best performance in history by finishing first in their group that consisted of three former World Cup champions: Uruguay, Italy, and England. During the Round of 16 they defeated Greece 5–3 via a penalty shootout after a 1–1 draw. Moreover, during the match against a much better team, Navas saved more than 15 shots due to the Costa Rican very weak defense. The match was characterized as "Navas vs Greece". They reached the quarterfinals for the very first time as the Ticos were defeated by the Netherlands also in a penalty shootout (3–4) after a scoreless draw on 5 July. Their 2018 World Cup campaign ended in a 4th place group stage exit with their only point coming from a 2-2 draw vs Switzerland.

Question: How many days did the battle the Baron was killed in last? Passage:While they were travelling to Europe in 1914, the First World War broke out and the ship carrying Von Wolf and his wife was diverted to Rio de Janeiro. Jayta Humphreys had retained her American citizenship and found passage to Europe on a Dutch ship; legend has it the Baron had to travel disguised as a woman. On arrival in Europe the Baron rejoined the German army, and was killed at the Battle of the Somme in 1916, just two weeks after signing up. His wife could not bring herself to return to Namibia alone and never again laid claim to the majestic castle. She stayed on the coast of the Tegernmeer in Bavaria (since her stepfather had been appointed consul general in Munich), before settling in the late 1930s in Zurich, where she met and married Erich Schlemmer, the consul general of Siam. After the Von Wolfs left South Africa, their friend Max Count von Lüttichau was given executorship of the farm, but it declared bankruptcy shortly after World War I, and since the South African government paid no compensation for this or several wartime raids, the house was sold for £7,500 to the Swedish Murrmann family. The new owner died shortly after his arrival and his son was killed in World War II, following which the castle was sold for 25,000 pounds to the private company Duwisib Pty Ltd and the rest of the land was divided and sold off. Jayta returned to the US to stay with her parents in Summit, New Jersey. Several changes in ownership later, the castle was acquired by the government in 1979 and extensively refurbished in 1991.

Question: Which neighbouring village to Homberg had the most residents? Passage:The mediaeval historical development that Homberg experienced closely matches that experienced by neighbouring villages such as Kirrweiler, Deimberg, Buborn, Langweiler and Hausweiler. Like these places, Homberg belonged until 1140 to the Nahegau, and then thereafter until 1263 to the Waldgraviate, which itself had arisen from the Nahegau. As far as is now known, Homberg had its first documentary mention in 1319. In the document in question, an arbitrator confirmed that Waldgrave Friedrich of Kyrburg had to forgo all his claims to rights to Hoenberg and a series of other places in the “Gericht auf der Höhe” (“Court on the Heights”). The Gericht auf der Höhe was said to be a constituent district of the “Hochgericht auf der Heide” (“High Court on the Heath”), which comprised, roughly, lands in a triangle bounded by the Nahe, the Glan and the Steinalp (another river). The 1319 document dealt with a dispute between the two Waldgravial sidelines of Kyrburg and Dhaun-Grumbach. About 1344, in his own documents, the name “Friedrich von Hoenberg” appeared. He was obviously a nobleman who came from Homberg, but nothing else about him has come to light. The villages under the Gericht auf der Höhe, among which was Homberg, were pledged first, in 1363, by Johann von Dhaun to Sponheim-Starkenburg and then in 1443 by Waldgrave and Rhinegrave Friedrich to the last of the Counts of Veldenz, namely Friedrich III, whose daughter Anna married King Ruprecht's son Count Palatine Stephan. The document whereby this arrangement was laid out referred to the village's inhabitants as the “poor people of Grumbach”. By uniting his own Palatine holdings with the now otherwise heirless County of Veldenz – his wife had inherited the county upon her father Friedrich III's death in 1444, but not his comital title – and by redeeming the hitherto pledged County of Zweibrücken, Stephan founded a new County Palatine, as whose comital residence he chose the town of Zweibrücken: the County Palatine – later Duchy – of Palatinate-Zweibrücken. Thus, Homberg, and the other villages, too, lay within this duchy, but they were all returned to the Waldgraviate in 1477 when the pledge was redeemed.
