Given the task definition, example input & output, solve the new input case.
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.
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.
Output: Who believes Fagin's gang make wallets and handkerchiefs?.
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.

New input case for you: Passage: On March 14, 1913, the Indiana General Assembly adopted "On the Banks of the Wabash, Far Away" as the official state song. The song's lyrics and required uses were added to the Indiana Code. The state song was the first official symbol of Indiana, adopted four years before the state flag. In 1925 Indiana General Assembly passed legislation that required Indiana's public school teachers to teach the song as part of their curriculum. That same year the New York Times reported that 20,000 copies of the song were distributed to the state's public school teachers. The song is often played at major sporting events, including the Indianapolis 500.Although "On the Banks of Wabash, Far Away" is Indiana's official song, "Back Home Again in Indiana" is more widely used and is falsely believed by many to be the state song. One of the leading causes of the state song's fall into obscurity was a change in its use at the Indianapolis 500 during the 1940s. "On the Banks of the Wabash, Far Away" is played at the event as the race cars move into their starting positions, a period that receives little television coverage, while "Back Home Again in Indiana" is sung just before the start of the race and is broadcast publicly. The change to singing "Back Home Again in Indiana" at public events continued in the following years, and it is often played in the place of "On the Banks of the Wabash, Far Away" at state college football games and other prominent events. In 1997, to commemorate the song's centennial anniversary, the Indiana General Assembly passed a resolution reconfirming "On the Banks of the Wabash, Far Away" as the state's official song and urged state institutions to make more use of it and return it to popularity.
Output:
In what year did the song that was adopted as the state song of Indiana get reconfirmed?
