[EX Q]: Passage: The Lookout Mountain Incline Railway is a inclined plane funicular railway leading to the top of Lookout Mountain from the historic St. Elmo neighborhood of Chattanooga, Tennessee. Passengers are transported from St. Elmo's Station at the base, to Point Park at the mountain summit, which overlooks the city and the Tennessee River. It is just a short drive to three of Chattanooga's main tourist attractions, Ruby Falls, Cavern Castle, and Rock City. The railway is approximately in length (single-track except for a short two-track passing loop at the midway point, allowing operation of two cars at one time). It has a maximum grade of 72.7%, making it one of the world's steepest passenger railways. It obtained Historic Mechanical Engineering Landmark status in 1991. The cable system for the cars was made by the Otis Elevator Company.
Link Information: The company pioneered the development of the "safety elevator", invented by Otis in 1852, which used a special mechanism to lock the elevator car in place should the hoisting ropes fail.
Question: In what year did the Otis Elevator Company first use the cable system for their railway cars?
[EX A]: Answer: 1852

[EX Q]: Passage: The Crag Group is a geological group outcropping in East Anglia, UK and adjacent areas of the North Sea. Its age ranges from approximately 4.4 to 0.478 million years BP, spanning the late Pliocene and early to middle Pleistocene epochs. It comprises a range of marine and estuarine sands, gravels, silts and clays deposited in a relatively shallow-water, tidally-dominated marine embayment on the western margins of the North Sea basin. The sands are characteristically dark green from glauconite but weather bright orange, with haematite 'iron pans' forming. The lithology of the lower part of the Group is almost entirely flint. The highest formation in the Group, the Wroxham Crag, contains over 10% of far-travelled lithologies, notably quartzite and vein quartz from the Midlands, igneous rocks from Wales, and chert from the Upper Greensand of southeastern England. This exotic rock component was introduced by rivers such as the Bytham River and Proto-Thames.
Link Information: The North Sea is a marginal sea of the Atlantic Ocean located between Great Britain (particularly England and Scotland), Denmark, Norway, Germany, the Netherlands, Belgium and France. An epeiric (or "shelf") sea on the European continental shelf, it connects to the ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than 970 km long and 580 km wide, with an area of 570000 km2 Question: What is the area in meters of the sea that is adjacent to the Crag Group?
[EX A]: Answer: 570000

[EX Q]: Passage: In 2006, Rossum appeared in Poseidon, Wolfgang Petersen's remake of the disaster film The Poseidon Adventure. She played Jennifer Ramsey, the daughter of Kurt Russell's character.

Rossum also appeared as Juliet Capulet in a 2006 Williamstown Theatre Festival production of William Shakespeare's Romeo and Juliet. In early 2009, Rossum appeared in Dragonball Evolution. Her next big screen venture was the indie Dare which was an official selection of the 2009 Sundance Film Festival. In November 2009, Rossum appeared in Broadway's 24 Hour Plays in which actors, writers, and directors collaborate to produce, and perform six one-act plays within 24 hours to benefit the Urban Arts Partnership. Rossum appeared in Warren Leight's "Daily Bread", directed by Lucie Tiberghien.
