[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: What country won the most medals at the competition that Kim qualified for by placing second in the Asian Championships? Passage:Kim qualified for the North Korean squad in the women's middleweight class (70 kg) at the 2004 Summer Olympics in Athens, by placing second and receiving a berth from the Asian Championships in Almaty, Kazakhstan. She easily thwarted Angola's Antonia Moreira with an earth-shattering ippon in her opening match, before succumbed to a similar tactic and an sumi gaeshi (corner reversal) hold from Australia's Catherine Arlove. In the repechage round, Kim chased Czech judoka and two-time Olympian Andrea Pažoutová with a sensational ōuchi gari (big inner reap) throw to score a waza-ari (half point) within a five-minute limit, but her rigid form was not enough to combat Belgium's Catherine Jacques in their subsequent match, relegating Kim into the seventh position.

[EX Q]: Question: How old was Arrhenius when he found the rock? Passage:In 1787, Swedish part-time chemist Carl Axel Arrhenius found a heavy black rock near the Swedish village of Ytterby, Sweden (part of the Stockholm Archipelago). Thinking that it was an unknown mineral containing the newly discovered element tungsten, he named it ytterbite. Finnish scientist Johan Gadolin identified a new oxide or "earth" in Arrhenius' sample in 1789, and published his completed analysis in 1794; in 1797, the new oxide was named yttria. In the decades after French scientist Antoine Lavoisier developed the first modern definition of chemical elements, it was believed that earths could be reduced to their elements, meaning that the discovery of a new earth was equivalent to the discovery of the element within, which in this case would have been yttrium. Until the early 1920s, the chemical symbol "Yt" was used for the element, after which "Y" came into common use. Yttrium metal was first isolated in 1828 when Friedrich Wöhler heated anhydrous yttrium(III) chloride with potassium to form metallic yttrium and potassium chloride.
