Question

question 3 based on information in the article, which of these happened third? a. uba researchers recorded songs that the chingolos were currently singing. b. uba researchers placed three devices in a park to play songs to the chingolos. c. uba researchers used ai to identify which chingolo songs were still sung. d. uba researchers developed a song based on the way chingolos produce notes. submit

Explanation:

The article mentions that researchers at the University of Buenos Aires (UBA) found the song and created a robotic tutor to reteach it to the chingolos. It also states that the old - but - goodie (the song) is back. This implies that the researchers used AI (the robotic tutor which can be considered an AI application in this context) to re - introduce the song. Option C is incorrect as the text says the song was no longer sung for years. Option A is wrong because the text indicates the song was not currently being sung in the normal way (it was restored). Option B is not mentioned in the text. Option D is about notes production which is not the main focus. The key is that the researchers (UBA) used a method (similar to using AI in a sense of creating a tutor) to re - introduce the song, and the most relevant among the options is that UBA researchers developed a song (the re - introduced one) based on the way chingolos produce notes (the original song structure).

Answer:

D. UBA researchers developed a song based on the way chingolos produce notes.
