Passage: The V&A has its origins in the Great Exhibition of 1851, with which Henry Cole, the museum's first director, was involved in planning; initially it was known as the Museum of Manufactures, first opening in May 1852 at Marlborough House, but by September had been transferred to Somerset House. At this stage the collections covered both applied art and science. Several of the exhibits from the Exhibition were purchased to form the nucleus of the collection. By February 1854 discussions were underway to transfer the museum to the current site and it was renamed South Kensington Museum. In 1855 the German architect Gottfried Semper, at the request of Cole, produced a design for the museum, but it was rejected by the Board of Trade as too expensive. The site was occupied by Brompton Park House; this was extended including the first refreshment rooms opened in 1857, the museum being the first in the world to provide such a facility. Question: The V&A has its origins in which world exposition?

Ex Output:
Great Exhibition of 1851

Passage: In 2010 the Amazon rainforest experienced another severe drought, in some ways more extreme than the 2005 drought. The affected region was approximate 1,160,000 square miles (3,000,000 km2) of rainforest, compared to 734,000 square miles (1,900,000 km2) in 2005. The 2010 drought had three epicenters where vegetation died off, whereas in 2005 the drought was focused on the southwestern part. The findings were published in the journal Science. In a typical year the Amazon absorbs 1.5 gigatons of carbon dioxide; during 2005 instead 5 gigatons were released and in 2010 8 gigatons were released. Question: How many areas were impacted by the the death of vegetation in the 2010 drought?

Ex Output:
three epicenters

Passage: Although the reciprocating steam engine is no longer in widespread commercial use, various companies are exploring or exploiting the potential of the engine as an alternative to internal combustion engines. The company Energiprojekt AB in Sweden has made progress in using modern materials for harnessing the power of steam. The efficiency of Energiprojekt's steam engine reaches some 27-30% on high-pressure engines. It is a single-step, 5-cylinder engine (no compound) with superheated steam and consumes approx. 4 kg (8.8 lb) of steam per kWh.[not in citation given] Question: How many cylinders does the Energiprojekt AB engine have?

Ex Output:
5
