instruction: Tell me about the RMS Adriatic
context: RMS Adriatic was a British ocean liner of the White Star Line. She was the fourth of a quartet of ships of more than 20,000 GRT, dubbed The Big Four. The ship was the only one of the four which was never the world's largest ship. However, she was the largest, the fastest, and the most luxurious of the Big Four, being the first ocean liner to have an indoor swimming pool and a Turkish bath.
  
  She began her career on the brand new route from Southampton to New York before joining, from 1911, her sister ships on the secondary route from Liverpool. They were in fact slow liners intended to provide a service at moderate prices. When World War I broke out, the Adriatic was among the ships that continued their civilian transatlantic service, while carrying many provisions. In 1917, she was requisitioned and served as a troop transport.
  
  After the war, she was refitted several times, and was gradually used for cruises, which became her main services in the 1930s. When Cunard Line and White Star Line merged in 1934, she was quickly deemed unnecessary and sold at the end of the year. She was scrapped in Osaka in 1935.
