In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Let me give you an example: Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
The answer to this example can be: Who believes Fagin's gang make wallets and handkerchiefs?.
Here is why: This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.

OK. solve this:
Passage: In 1979, the locomotive was renumbered "1881", painted black with silver stripes, and leased to a Hollywood company for use in the filming of the horror movie Terror Train (1979), starring Jamie Lee Curtis. In 1980, the locomotive was repainted with a color scheme used by Canadian Pacific in the 1930s.  The black, gold, and Tuscan red paint job was popular with railroad enthusiasts and photographers.  The number 1293 was also restored to the engine.  In February 1982, the headlights, handrails, and cab roof of 1293 were damaged when the roof of a Steamtown storage building gave way to heavy snow.Although the Steamtown Special History Study reasoned that, since this type of locomotive had historically operated in New England, perhaps as far south as Boston, it qualified to be part of the federal government's collection, the Canadian native sat unused for 12 years following the move to Scranton. Ohio Central Railroad System purchased it in 1996, and it underwent a 13-month restoration.  As of July 2010, Ohio Central Railroad has lost control of most of its holdings, but former owner, Jerry Joe Jacobson, maintained a collection of vintage equipment including CPR 1293 and her sister, CRP 1278, which is also a veteran of Steamtown, U.S.A. operational locomotives. No. 1293 is still operational as of October 2011.Canadian Pacific Railway No. 1278, like her sister, CPR 1293, was also built by Canadian Locomotive Company in 1948, and is a type 4-6-2, class G5d light-weight "Pacific" locomotive.  It was purchased by Blount in May 1965, and renumbered 127.  Blount had planned to renumber all three of the series 1200 CRP locomotives in his collection from 1246, 1278, and 1293 to 124, 127 and 129 respectively, but 1278 was the only one of the three that underwent the change.  The new number remained on the locomotive from 1966 until 1973, when its former number was restored.  The locomotive was leased to the Cadillac and Lake City Railroad in Michigan from 1970 to 1971.  After some repair work, the locomotive was returned to Bellows Falls where it served on excursion runs. After moving to Scranton, CPR 1278 was traded to the Gettysburg Steam Railroad in Pennsylvania.
Answer:
What is the number of the locomotive that was leased to Cadillac and Lake City Railroad in Michigan from 1970 to 1971?
