Question

metody they re singing nowadays was sung in the 1960s. then they stopped singing it for many years and no longer knew it. remarkably, the oldie - but - goodie is back. this is thanks to researchers at the university of buenos aires (uba). they found the song and created a robotic tutor to reteach it to the chingolos. what prompted the researchers to reintroduce the song? why had the chingolos \forgotten,\ it, and how was it rediscovered? heres the birds - eye view. male chingolos learn their songs in infancy. they imitate the ones they hear their fathers sing. the songs are short, and each chingolo sings a different one. its their way of marking their territory and of letting female chingolos know where they are. now suppose a chingolo community experiences loss of habitat or of adult tutors. the teaching process might be threatened. young chingolos might not learn their melodies. and an important part of their bird culture would be lost forever. these possibilities motivated the researchers at uba. they wanted to see if they could preserve the chingolos songs. so, they taught the birds a lost song with the help of a robotic tutor. so, how do you find a birdsong after its lost? fortunately, back in the 1960s, an animal scientist wrote down many of the melodies chingolos were singing in the park at the time. he used handwritten symbols to represent the notes. the uba researchers then recorded the songs that the chingolos were question 2 according to the article, what is one reason why only three chingolo melodies remained from the 1960s? a. the chingolos chose to only sing the songs that best protected their territory. b. migration decreased the chingolo population in certain areas of argentina. c. researchers confused the chingolos by introducing them to too many new songs. d. the chingolos stopped singing due to the low temperatures in buenos aires. submit

Explanation:

The article mentions that in the 1960s, an animal scientist wrote down many of the melodies (the chingolo songs). The UBA researchers then recorded the songs that the chingolos were singing in the park at that time. This implies that the melodies from the 1960s were preserved through the scientist's written work and the UBA's recordings. Option A aligns with this as it suggests the chingolos chose to only sing the songs that were best protected (i.e., the ones from the 1960s that were documented).

Answer:

A. The chingolos chose to only sing the songs that best protected their territory.
