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: In what modern-day country is the mountain where Pilate violently suppressed an armed Samaritan movement? Passage:Although Pilate is the best-attested governor of Judaea, few sources on his rule have survived. He appears to have belonged to the well-attested Pontii family, but nothing is known for certain about his life before he became governor of Judaea, nor of the circumstances that led to his appointment to the governorship. A single inscription from Pilate's governorship has survived, the so-called Pilate stone, as have coins that he minted. The Jewish historian Josephus and philosopher Philo of Alexandria both mention incidents of tension and violence between the Jewish population and Pilate's administration. Many of these involve Pilate acting in ways that offended the religious sensibilities of the Jews. The Christian Gospels record that Pilate ordered the crucifixion of Jesus at some point during his time in office; Josephus and the Roman historian Tacitus also appear to have recorded this information. According to Josephus, Pilate's removal from office occurred because he violently suppressed an armed Samaritan movement at Mount Gerizim. He was sent back to Rome by the legate of Syria to answer for this before Tiberius, who, however, had died before he arrived. Nothing is known for certain about what happened to him after this. On the basis of a mention in the second-century pagan philosopher Celsus and Christian apologist Origen, most modern historians believe that Pilate simply retired after his dismissal. Modern historians have differing assessments of Pilate as an effective ruler; while some believe he was a particularly brutal and ineffective governor, others argue that his long time in office means he must have been reasonably competent. According to one prominent post-war theory, Pilate was motivated by antisemitism in his treatment of the Jews, but this theory has been mostly abandoned.

Question: In what city and country was the  Jagdgeschwader 77 based? Passage:Born in Cologne-Lindenthal, Reinert volunteered for military service in the National Socialist Luftwaffe in 1938. Following flight training, he was posted to Jagdgeschwader 77 (JG 77—77th Fighter Wing). He fought in Operation Barbarossa, the German invasion of the Soviet Union, and claimed his first aerial victory on 8 August 1941. He received the Knight's Cross of the Iron Cross following his 53rd aerial victory. Accumulating further victories, he surpassed the century mark in October 1942 for which he was awarded the Knight's Cross of the Iron Cross with Oak Leaves. In November 1942, his unit was transferred to the Mediterranean theatre in support of the Afrika Korps. There, Reinert claimed 51 victories against the Western Allies. In August 1943, he was appointed Staffelkapitän (squadron leader) of 1. Staffel (1st squadron) of JG 77, and in February 1944 the 8. Staffel of Jagdgeschwader 27 (JG 27—27th Fighter Wing) based in France. Reinert was then appointed Gruppenkommandeur (group commander) of IV. Gruppe (4th group) of JG 27 and, credited with 174 aerial victories, received the Knight's Cross of the Iron Cross with Oak Leaves and Swords on 30 January 1945. He then received conversion training to the then new Messerschmitt Me 262 jet fighter and was posted to Jagdgeschwader 7 (JG 7—7th Fighter Wing), an all-jet fighter wing.

Question: Which ruler was in power longer, Radu I or Dan I? Passage:There is evidence that the Second Bulgarian Empire ruled at least nominally the Wallachian lands up to the Rucăr–Bran corridor as late as the late 14th century. In a charter by Radu I, the Wallachian voivode requests that tsar Ivan Alexander of Bulgaria order his customs officers at Rucăr and the Dâmboviţa River bridge to collect tax following the law. The presence of Bulgarian customs officers at the Carpathians indicates a Bulgarian suzerainty over those lands, though Radu's imperative tone hints at a strong and increasing Wallachian autonomy. Under Radu I and his successor Dan I, the realms in Transylvania and Severin continued to be disputed with Hungary. Basarab was succeeded by Nicholas Alexander, followed by Vladislav I. Vladislav attacked Transylvania after Louis I occupied lands south of the Danube, conceded to recognize him as overlord in 1368, but rebelled again in the same year; his rule also witnessed the first confrontation between Wallachia and the Ottoman Empire (a battle in which Vladislav was allied with Ivan Shishman). After the Magyar conquest (10-11th century), Transylvania had become an autonomous and multi-ethnic voivodeship led by a voivode appointed by the King of Hungary until the 16th century. Several Kings of Hungary invited settlers from Central and Western Europe, such as the Saxons, to come to Transylvania and occupy the region. The Szeklers were brought to southeastern Transylvania as border guards. Romanians are mentioned by the Hungarian documents (township called Olahteluk) in the 13th century (1283) in Bihar County. The "land of Romanians" (Terram Blacorum) appeared in Fogaras, and this area was mentioned under the name "Olachi" in 1285. After the collapse of the Hungarian Kingdom (following the disastrous Battle of Mohács, 1526) the region became the independent Principality of Transylvania until 1711.
