Question: What age was Robert I the year the Battle of Bannockburn occurred? Passage:Scottish field armies rarely managed to stand up to the usually larger and more professional armies produced by England, but they were used to good effect by Robert I of Scotland at the Battle of Bannockburn in 1314 to secure Scottish independence. He adopted a policy of slighting castles and made use of naval power to support his forces, beginning to develop a royal Scottish naval force. In the Late Middle Ages under the Stewart kings these forces were further augmented by specialist troops, particularly men-at-arms and archers, hired by bonds of manrent, similar to English indentures of the same period. New "livery and maintenance" castles were built to house these troops and castles began to be adapted to accommodate gunpowder weapons. The Stewarts also adopted major innovations in continental warfare, such as longer pikes, the extensive use of artillery, and they built up a formidable navy. However, one of the best armed and largest Scottish armies ever assembled still met with defeat at the hands of an English army at the Battle of Flodden in 1513, which saw the destruction of a large number of ordinary troops, a large section of the nobility and King James IV.

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: Which Mesopotamian civilization's city has the most people at its peak? Passage:A vast number of artifacts have been discovered from ancient Mesopotamia depicting explicit heterosexual sex. Glyptic art from the Sumerian Early Dynastic Period frequently shows scenes of frontal sex in the missionary position. In Mesopotamian votive plagues from the early second millennium BC, the man is usually shown entering the woman from behind while she bends over, drinking beer through a straw. Middle Assyrian lead votive figurines often represent the man standing and penetrating the woman as she rests on top of an altar. Scholars have traditionally interpreted all these depictions as scenes of ritual sex, but they are more likely to be associated with the cult of Inanna, the goddess of sex and prostitution. Many sexually explicit images were found in the temple of Inanna at Assur, which also contained models of male and female sexual organs, including stone phalli, which may have been worn around the neck as an amulet or used to decorate cult statues, and clay models of the female vulva.
