Input: Question: Was King John IV of Portugal still alive when The Anglo-Maratha wars ended? Passage 1:In 1979 Williams won his first British National Hill Climb Championships setting a new course record that still stands to this day. A rival, Andy Hitchens, who remembers it well, said: "Williams looked like he'd been on starvation rations for months — he was built like a sparrow. Some people assume that there was a howling tailwind that day, but there wasn't. It was sunny, but cool.” In 1980 Williams joined the Manchester Wheelers' Club and was expected to win International honours during the next two or three seasons. Later that year he won his first stage in the Sealink International finishing four minutes clear. However Williams was left disappointed in the National Hill Climb Championships that year beaten into second place by Malcolm Elliott by only one fifth of a second after being knocked off his bike whilst warming up and receiving a broken nose and severe bruising. At the age of 21 Williams competed for Great Britain in the individual road race at the 1980 Moscow Olympic Games. He was sponsored by Harry Hall Cycles. Williams finished 47th, alongside Stephen Roche. At the end of the 1980 season Williams publicly declared his intention of living and racing in France for the 1981 racing calendar with a view to turning professional therefore joining the French club ACBB (Athletic Club de Boulogne Billencourt), Europe’s most successful sports club.
 Passage 2:The Bombay Presidency was created when the city of Bombay was leased in fee tail to the East India Company by a Royal Charter from the King of England, Charles II, who had in turn acquired it on May 11, 1661, when his marriage treaty with Catherine of Braganza, daughter of King John IV of Portugal, placed the islands of Bombay in possession of the English Empire, as part of Catherine's dowry to Charles. The English East India Company transferred its Western India headquarters from Surat, its first colony in that region, to Bombay in 1687. The Presidency was brought under British Parliament control along with other parts of British India through Pitt's India Act. Major territorial acquisitions were made during the Anglo-Maratha Wars when the whole of the Peshwa's dominions and much of the Gaekwad's sphere of influence were annexed to the Bombay Presidency in different stages till 1818. Aden was annexed in 1839, while Sind was annexed by the Company in 1843 after defeating the Talpur dynasty in the Battle of Hyderabad and it was made a part of the Bombay Presidency.
 Passage 3:Sited at the confluence of the rapidly flowing Lehigh River's waters with the more stately waters of the deeper wider Delaware, Easton became a major commercial center during the canal and railroad periods of the 19th century, when it would become a transportation hub for the eastern steel industry. The Delaware Canal, was quickly built soon after the lower Lehigh Canal (1818) became effective in regularly and reliably delivering much needed anthracite coal, into more settled lands along the rivers. And eventually the Morris would also serve to connect the rapidly developing Coal Regions to the north and west, to the fuel starved iron works to the west, the commercial port of Philadelphia to the south, and to the many home owners seeking fuel for heat within Pennsylvania, Maryland, New Jersey, Delaware and New York. Seeing other ways of exploiting the new fuel source, other entrepreneurs quickly moved to connect across the Delaware River reaching into the New York City area to the east via a connection with the Morris Canal in Phillipsburg, New Jersey, so the town became a canal nexus or hub from which the Coal from Mauch Chunk reached the world. The early railroads were often built to parallel and speed shipping along transportation corridors, and by the late 1860s the Lehigh and Susquehanna Railroad (LH&S) and Lehigh Valley Railroad (LVRR) were built to augment the bulk traffic through the canals and provide lucrative passenger travel services. The LVRR, known as 'the Black Diamond Line' would boast the twice daily "Black Diamond Express" daily passenger trains to and from New York City and Buffalo, New York via Easton. The Central Railroad of New Jersey (CNJ), would lease and operate the LH&S tracks from the 1870s until the Conrail consolidations absorbed both the Central Railroad of New Jersey and Lehigh Valley Railroad in 1966. Today, the Lehigh Valley Railroad's main line is the only major rail line that goes through Easton and is now known as the Lehigh Line; the Lehigh Line was bought by the Norfolk Southern Railway in 1999.
