[EX Q]: Question: How many books has the author of the children's book that inspired the character of Princess Fiona written? Passage:Created by screenwriters Ted Elliott and Terry Rossio, Fiona is loosely based on the unsightly princess in William Steig's children's book Shrek!, from which her role and appearance were significantly modified. The screenwriters adapted the character into a princess under a shapeshifting enchantment, an idea that was initially greatly contested by other filmmakers. Fiona is voiced by actress Cameron Diaz. Comedian and actress Janeane Garofalo was originally cast as the character until she was fired from the first film with little explanation, although it is believed that the producers found Garofalo's sarcastic approach to the princess unsuitable after Shrek's original voice actor died. Fiona was one of the first human characters to have a lead role in a computer-animated film, thus the animators aspired to make her both beautiful and realistic in appearance. However, an early test screening resulted in children reacting negatively towards the character's uncanny realism, prompting the animators to re-design Fiona into a more stylized, cartoonish heroine.

[EX Q]: Question: Is the person who served as Lebanese President during 1982 still alive? Passage:According to historians William Cleveland and Martin Bunton, Beirut became an international banking center because of its "laissez-faire economic system". Business owners from Cairo, Damascus, and Baghdad moved to Beirut for economic opportunities. Despite Lebanon's cultural liberalism and economic prosperity, sectarian tensions remained as citizens identified themselves through their sects. With Muslims calling for greater representation and with Cold War tensions, Lebanese leadership had to decide whether to ally with the West or with Egypt, Syria and its Arab history. Christians wanted to continue alliances with the West but Muslims were drawn to Nasser's pan-Arabism. Multiple factors including sectarian tensions and Palestinian refugee settlement in southern Lebanon contributed to the beginnings of the Lebanese Civil War. In 1976, Syrian President Hafez al-Assad sent troops into Lebanon to fight PLO forces on behalf of Christian militias. This led to escalated fighting until a cease-fire agreement later that year that allowed for the stationing of Syrian troops within Lebanon. The Syrian presence in Lebanon quickly changed sides; soon after they entered Lebanon they had flip-flopped and began to fight the Christian nationalists in Lebanon they allegedly entered the country to protect. The Kateab Party and the Lebanese Forces under Bachir Gemayel strongly resisted the Syrians in Lebanon. Following the Israeli invasion into Lebanon in 1982, new Lebanese President Amine Gemayel sought the support of Syrian troops to stabilize the region. Syria fought Israeli troops after the latter's invasion of Lebanon.

[EX Q]: Question: What ocean was the Isle of Sheppey in? Passage:At the beginning of the ninth century, England was almost wholly under the control of the Anglo-Saxons. The Midland kingdom of Mercia dominated southern England, but their supremacy came to an end in 825 when they were decisively defeated by Ecgberht at the Battle of Ellendun. The two kingdoms became allies, which was important in the resistance to Viking attacks. In the same year Ecgberht sent his son thelwulf to conquer the Mercian sub-kingdom of Kent (the area of the modern county plus Essex, Surrey and Sussex) and appointed him sub-king. In 835 the Isle of Sheppey was ravaged by Vikings and in the following year they defeated Ecgberht at Carhampton in Somerset, but in 838 he was victorious over an alliance of Cornishmen and Vikings at the Battle of Hingston Down, reducing Cornwall to the status of a client kingdom. He died in 839 and was succeeded by thelwulf, who appointed his eldest son thelstan as sub-king of Kent. thelwulf and Ecgberht may not have intended a permanent union between Wessex and Kent as they both appointed sons as sub-kings and charters in Wessex were attested (witnessed) by West Saxon magnates, while Kentish charters were witnessed by the Kentish elite; both kings kept overall control and the sub-kings were not allowed to issue their own coinage.
