Problem: Text: Westminster Abbey, formally titled the Collegiate Church of St Peter at Westminster, is a large, mainly Gothic abbey church in the City of Westminster, London, England, just to the west of the Palace of Westminster. It is one of the United Kingdom's most notable religious buildings and the traditional place of coronation and burial site for English and, later, British monarchs. The building itself was a Benedictine monastic church until the monastery was dissolved in 1539. Between 1540 and 1556, the abbey had the status of a cathedral. Since 1560, the building is no longer an abbey or a cathedral, having instead the status of a Church of England ''Royal Peculiar''--a church responsible directly to the sovereign.

Problem: Text: The Amazon river dolphin is the largest species of river dolphin, with adult males reaching 185 kilograms (408 lb) in weight, and 2.5 metres (8.2 ft) in length. Adults acquire a pink color, more prominent in males, giving it its nickname ''pink river dolphin''. Sexual dimorphism is very evident, with males measuring 16% longer and weighing 55% more than females. Like other toothed whales, they have a melon, an organ that is used for bio sonar. The dorsal fin, although short in height, is regarded as long, and the pectoral fins are also large. The fin size, unfused vertebrae, and its relative size allow for improved manoeuvrability when navigating flooded forests and capturing prey.

Question: is there such a thing as pink dolphins?
A:
yes
