Q: Question: "What could be seen along with Jesus on the cross?"  Context: "According to the canonical gospels, Jesus, whom Christians believe to be the Son of God as well as the Messiah (Christ), was arrested, tried, and sentenced by Pontius Pilate to be scourged, and finally crucified by the Romans. Jesus was stripped of his clothing and offered wine mixed with gall to drink, before being crucified. He was then hung for six hours (according to Mark's Gospel) between two convicted thieves. During this time, the soldiers affixed a sign to the top of the cross stating "Jesus of Nazareth, King of the Jews" in three languages. They then divided his garments among them, but cast lots for his seamless robe. After Jesus' death they pierced his side with a spear to be certain that he had died. The Bible records seven statements that Jesus made while he was on the cross, as well as several supernatural events that occurred."  Answer:
A: a sign to the top of the cross stating "Jesus of Nazareth, King of the Jews" in three languages

Q: Question: "Who had the higher number of votes between Labour and The Conservatives after the 2010 election?"  Context: "In the 2010 general election on 6 May that year, Labour with 29.0% of the vote won the second largest number of seats (258). The Conservatives with 36.5% of the vote won the largest number of seats (307), but no party had an overall majority, meaning that Labour could still remain in power if they managed to form a coalition with at least one smaller party. However, the Labour Party would have had to form a coalition with more than one other smaller party to gain an overall majority; anything less would result in a minority government. On 10 May 2010, after talks to form a coalition with the Liberal Democrats broke down, Brown announced his intention to stand down as Leader before the Labour Party Conference but a day later resigned as both Prime Minister and party leader."  Answer:
A: The Conservatives

Q: Question: "The rebels gained representation because of what event causing the uprising?"  Context: "Accusing the rebels of being "drugged" and linked to al-Qaeda, Gaddafi proclaimed that he would die a martyr rather than leave Libya. As he announced that the rebels would be "hunted down street by street, house by house and wardrobe by wardrobe", the army opened fire on protests in Benghazi, killing hundreds. Shocked at the government's response, a number of senior politicians resigned or defected to the protesters' side. The uprising spread quickly through Libya's less economically developed eastern half. By February's end, eastern cities like Benghazi, Misrata, al-Bayda and Tobruk were controlled by rebels, and the Benghazi-based National Transitional Council (NTC) had been founded to represent them."  Answer:
A:
the army opened fire
