Your job is to generate a question that can use the information provided to obtain the given answer. You should use the information on both passage and link information to create the question. Note that the answer to the question should be exactly the given answer, and if the answer is none, the answer to the question shouldn't be obtainable from the passage or linked information.

Input: Consider Input: Passage: In 1971, Bob Shad, who had worked with her as producer at Mercury, asked her to record for his label, Mainstream, which he had founded after leaving Mercury. Breaking a four-year hiatus, Vaughan signed a contract with Mainstream and returned to the studio for A Time in My Life, a step away from jazz into pop music with songs by Bob Dylan, John Lennon, and Marvin Gaye arranged by Ernie Wilkins. She didn't complain about this eclectic change in direction, but she chose the material for her next album after admiring the work of Michel Legrand. He conducted an orchestra of over one hundred musicians for Sarah Vaughan with Michel Legrand, an album of compositions by Legrand with lyrics by Alan and Marilyn Bergman. The songs brought some of the musicians to tears during the sessions. But Shad wanted a hit, and the album yielded none. She sang a version of the pop hit "Rainy Days and Mondays" by the Carpenters for Feelin' Good. This was followed by Live in Japan, her first live album since 1963. Sarah Vaughan and the Jimmy Rowles Quintet (1974) was more experimental, containing free improvisation and some unconventional scatting.

Output: How many songs were on Vaughan's first album with Mainstream?


Input: Consider Input: Passage: The Anzac class originated from RAN plans to replace the six River-class destroyer escorts with a mid-capability patrol frigate. The Australian shipbuilding industry was thought to be incapable of warship design, so the RAN decided to take a proven foreign design and modify it. Around the same time, the Royal New Zealand Navy (RNZN) was looking to replace four Leander-class frigates; a deterioration in New Zealand-United States relations, the need to improve alliances with nearby nations, and the commonalities between the RAN and RNZN ships' requirements led the two nations to begin collaborating on the acquisition in 1987. Tenders were requested by the Anzac Ship Project at the end of 1986, with 12 ship designs (including an airship) submitted. By August 1987, the tenders were narrowed down in October to Blohm + Voss's MEKO 200 design, the M class (later Karel Doorman class) offered by Royal Schelde, and a scaled-down Type 23 frigate proposed by Yarrow Shipbuilders. In 1989, the Australian government announced that Melbourne-based shipbuilder AMECON (which became Tenix Defense) would build the modified MEKO 200 design. The Australians ordered eight ships, while New Zealand ordered two, with an unexercised option for two more.

Output: What other ships had Yarrow Shipbuilders completed the year they submitted a tender for the Anzac Ship Project?


Input: Consider Input: Passage: Baldwin built many 4-4-0 "American" type locomotives (the locomotive that built America). Surviving examples of which include the 1872 Countess of Dufferin and 1875's Virginia and Truckee Railroad No.22 "Inyo", but it was perhaps best known for the 2-8-2 "Mikado" and 2-8-0 "Consolidation" types. It was also well known for the unique cab-forward 4-8-8-2 articulateds built for the Southern Pacific Company and massive 2-10-2 for the Atchison, Topeka and Santa Fe Railway. Baldwin also produced their most powerful steam engines in history, the 2-8-8-4 "Yellowstone" for the Duluth, Missabe and Iron Range Railway. The Yellowstone could put down over of Tractive force. They routinely hauled 180 car trains weighing over . The Yellowstones were so good that the DM&IR refused to part with them; they hauled ore trains well into the diesel era, and the last one retired in 1963. Three have been preserved. One of Baldwin's last new and improved locomotive designs were the 4-8-4 "Northern" locomotives. Baldwin's last domestic steam locomotives were 2-6-6-2s built for the Chesapeake and Ohio Railway in 1949. Baldwin 60000, the company's 1926 demonstration steam locomotive, is on display at the Franklin Institute in Philadelphia. On a separate note, the restored and running 2-6-2 steam locomotive at Fort Edmonton Park was built by Baldwin in 1919.
 Link Information: The Southern Pacific Transportation Company was acquired by the Union Pacific Corporation and merged with their Union Pacific Railroad Answer: Union Pacific Corporation


Output: What is the name of the successor company for the company that received 4-8-8-2 articulateds?
