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.

Example Input: Question: What attributes did the goddess whose birthday was being observed commonly have associated with her? Passage:The Panathenaea (, "all-Athenian festival") was the most important festival for Athens and one of the grandest in the entire ancient Greek world. Except for slaves, all inhabitants of the polis could take part in the festival. This holiday of great antiquity is believed to have been the observance of Athena's birthday and honoured the goddess as the city's patron divinity, Athena Polias ('Athena of the city'). A procession assembled before dawn at the Dipylon gate in the northern sector of the city. The procession, led by the Kanephoros, made its way to the Areopagus and in front of the Temple of Athena Nike next to the Propylaea. Only Athenian citizens were allowed to pass through the Propylaea and enter the Acropolis. The procession passed the Parthenon and stopped at the great altar of Athena in front of the Erechtheum. Every four years a newly woven peplos was dedicated to Athena.

Example Input: 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.
