Question: Which shipmaker built the RMS Olympic for the White Star Line during the early 20th century?

full_context: Document 1: Olympic-class ocean liner: The "Olympic"-class ocean liners were a trio of British ocean liners built by the Harland & Wolff shipyard for the White Star Line during the early 20th century. They were "Olympic" (1911), "Titanic" (1912), and "Britannic" (1915). All three were designed to be the largest and most luxurious passenger ships in the world, designed to give White Star an advantage in the transatlantic passenger trade. Two were lost early in their careers: "Titanic" sank in 1912 on its maiden voyage, after hitting an iceberg in the North Atlantic Ocean, and "Britannic" in 1916, after hitting a mine laid by the minelayer submarine "U-73" in a barrier off Kea in the Aegean Sea during World War I. "Olympic", the lead vessel, had a career spanning 24 years and was retired in 1934 and sold for scrapping in 1935.
Document 2: Cunard-White Star Line: Cunard White Star Line, Ltd., was a British shipping line which existed between 1934 and 1949, It was created as an operating company to control the joint shipping assets of the Cunard Line and the White Star Line after both companies experienced financial difficulties during the Great Depression. Cunard White Star controlled a total of twenty-five large ocean liners (with Cunard contributing fifteen ships and White Star ten). Both Cunard and White Star were in dire financial trouble, and were looking to complete enormous liners: White Star had Hull 844 – RMS "Oceanic III" – and Cunard had Hull 534, which would later become  .
Document 3: Imperator-class ocean liner: The "Imperator" class ocean liners were a series of three ocean liners designed for the Hamburg America Line, commonly known as "HAPAG". These three ships were commissioned by the chairman of HAPAG Albert Ballin. Namely the "Imperator" (1912), the "Vaterland" (1913) and the largest, the "Bismarck" (1914). These liners were over 50,000 tons, sported three funnels and had a length ranging from 906 ft (276 m) to 955.8 ft (291.3 m). To this day, the "Vaterland" is the largest passenger ship operated by a German shipping company.
Document 4: RMS Aquitania: RMS "Aquitania" was a Cunard Line ocean liner designed by Leonard Peskett and built by John Brown & Company in Clydebank, Scotland. She was launched on 21 April 1913 and sailed on her maiden voyage to New York on 30 May 1914. "Aquitania" was the third in Cunard Line's "grand trio" of express liners, preceded by RMS "Mauretania" and  , and was the last surviving four-funnelled ocean liner. Widely considered one of the most attractive ships of her time, "Aquitania" earned the nickname "Ship Beautiful".
Document 5: RMS Olympic: RMS "Olympic" ( ) was a British transatlantic ocean liner, the lead ship of the White Star Line's trio of "Olympic"-class liners. Unlike her younger sister ships, "Olympic" had a long career, spanning 24 years from 1911 to 1935. This included service as a troopship during the First World War, which gained her the nickname "Old Reliable". "Olympic" returned to civilian service after the war and served successfully as an ocean liner throughout the 1920s and into the first half of the 1930s, although increased competition, and the slump in trade during the Great Depression after 1930, made her operation increasingly unprofitable.
Document 6: White Star Line: The Oceanic Steam Navigation Company or White Star Line of Boston Packers, more commonly known as just White Star Line, was a prominent British shipping company.
Document 7: HMS Royal Oak (08): HMS "Royal Oak" was one of five "Revenge"-class battleship s built for the Royal Navy during the First World War. Launched in 1914 and completed in 1916, "Royal Oak" first saw combat at the Battle of Jutland as part of the Grand Fleet. In peacetime, she served in the Atlantic, Home and Mediterranean fleets, more than once coming under accidental attack. The ship drew worldwide attention in 1928 when her senior officers were controversially court-martialled. Attempts to modernise "Royal Oak" throughout her 25-year career could not fix her fundamental lack of speed and by the start of the Second World War, she was no longer suited to front-line duty.
Document 8: SS Nomadic (1911): SS "Nomadic" is a former tender of the White Star Line, launched on 25 April 1911 in Belfast now on display in Belfast's Titanic Quarter. She was built to transfer passengers and mail to and from RMS "Olympic" and RMS "Titanic", and is the only White Star Line vessel in existence today.
Document 9: RMS Queen Mary 2: RMS "Queen Mary 2 (also referred to as the QM2") is a transatlantic ocean liner. She is the largest and only major ocean liner built for the British Cunard Line since "Queen Elizabeth 2" in 1969, the vessel she succeeded as flagship of the Cunard Line.
Document 10: Oceanic (unfinished ship): The RMMV (Royal Mail Motor Vessel) Oceanic was the planned name of an unfinished ocean liner that was partially built by Harland and Wolff for the White Star Line. The ship was to have been the first 1000 ft -long ocean liner. It was intended to be the largest ocean liner for the White Star Line, thus it would have been larger than the earlier White Star giants, "Olympic", "Titanic", "Britannic", and "Majestic".
Document 11: RMS Republic (1903): RMS Republic was a steam-powered ocean liner built in 1903 by Harland and Wolff in Belfast, and lost at sea in a collision six years later while sailing for the White Star Line. A CQD distress call was issued on the new Marconi radio device, the first recorded, resulting in the saving of around 1500 lives. Known as the "Millionaires' Ship" on account of the number of well-known and immensely rich Americans who traveled by her, she was described as a "palatial liner" and was the flagship of White Star Line's Boston service.

Document 13: RMS Homeric (1913): RMS "Homeric", originally launched as "Columbus", was built for Norddeutscher Lloyd and launched in 1913 at the F. Schichau yard in Danzig. "Columbus" was ceded to Great Britain in 1919 as part of German war reparations. She was sold to White Star Line in 1920, which named her "Homeric". Her sister ship "Hindenburg" retained her German ownership and was renamed "Columbus". "Homeric" was operated by White Star from 1922 to 1935.
Document 14: RMS Queen Mary: RMS "Queen Mary" is a retired ocean liner that sailed primarily on the North Atlantic Ocean from 1936 to 1967 for the Cunard Line (known as Cunard-White Star Line when the vessel entered service). Built by John Brown & Company in Clydebank, Scotland, "Queen Mary", along with  , were built as part of Cunard's planned two-ship weekly express service between Southampton, Cherbourg and New York. The two ships were a British response to the express superliners built by German, Italian and French companies in the late 1920s and early 1930s. "Queen Mary" was the flagship of the Cunard Line from May 1936 until October 1946 when she was replaced in that role by "Queen Elizabeth".
Document 15: RMS Titanic: RMS "Titanic" ( ) was a British passenger liner that sank in the North Atlantic Ocean in the early morning hours of 15 April 1912, after it collided with an iceberg during its maiden voyage from Southampton to New York City. There were an estimated 2,224 passengers and crew aboard the ship, and more than 1,500 died, making it one of the deadliest commercial peacetime maritime disasters in modern history. The RMS "Titanic" was the largest ship afloat at the time it entered service and was the second of three "Olympic"-class ocean liner s operated by the White Star Line. The Titanic was built by the Harland and Wolff shipyard in Belfast. Thomas Andrews, her architect, died in the disaster.
