Example Input: Question: Was the route updated before The Weavers' Triangle Visitor Centre was built? Passage:The route is described in a series of six sectional leaflets, updated in 2008, which are available from Burnley Tourist Information Centre. The first section begins at the Manchester Road canal bridge (where the Weavers' Triangle Visitor Centre is located), and follows the towpath of the Leeds and Liverpool Canal over the Burnley Embankment to Thompson Park. It then follows the River Brun through Bank Hall Park and past Heasandford House where it joins the route of the Brontë Way out of Burnley, almost to Lea Green Reservoir. It then passes the ruined Extwistle Hall and over the River Don to Queen Street Mill Textile Museum in Harle Syke. The second section crosses Todmorden Road, passing a number of farms and over Thursden brook. It then follows the road up the Thursden valley and crosses into West Yorkshire, descending to Widdop Reservoir. Joining the Mary Towneley Loop section of the Pennine Bridleway at the Gorpe track, it moves back into Lancashire and past Hurstwood Reservoir to the Elizabethan hamlet of Hurstwood.

Example Input: Question: How big was El Aguila the year it was purchased by Royal Dutch Shell? Passage:DeGolyer opened a petroleum geology consultancy in 1914, moving to Montclair, New Jersey to work in New York City in 1916. In 1919, while working as a consultant to the British entrepreneur Lord Cowdray, DeGolyer negotiated the sale of the El Aguila company to Royal Dutch Shell. In the same year, DeGolyer organized the formation of the Rycade Oil Company as well as the Amerada Petroleum Corporation for Lord Cowdray, rising to become general manager, president, and chairman from 1929 to 1932 DeGolyer left the firm in 1932, but remained with Rycade, which was established to explore salt dome oil deposits through 1941. As a geophysical consultant with Rycade, DeGolyer made the first torsion balance survey in the United States at the Spindletop oilfield. An oilfield found by DeGolyer on behalf of Rycade at Nash, Texas was the first oilfield anywhere to be discovered using geophysics. From 1925 DeGolyer established the Geophysical Research Corporation as a subsidiary of Amerada to develop reflection seismology techniques originated by J. Clarence Karcher and Eugene McDermott, leaving in 1932 to move to Dallas, Texas. DeGolyer provided financial support for the 1930 establishment of GRC's successor, Geophysical Service Incorporated. GSI went on to spin off Texas Instruments. In 1936 with Lewis MacNaughton, DeGolyer established the petroleum exploration consulting firm DeGolyer and MacNaughton, and Core Laboratories, Incorporated the same year to provide drilling core and fluids analysis. DeGolyer was also associated with the Atlatl Royalty Company from 1932 to 1950 and the Felmont Corporation in 1934. In 1956 he established Isotopes, Incorporated to provide radioactive isotopes for oilfield and industrial purposes.
