To find out whether mice put such sounds together in song-like 25 , the researchers recorded the sounds of 1 mice. Using computer 26 , they were able to separate the sounds into specific types of syllables(音節(jié)), and found the mice produced about 10 syllables per second.
The results showed that nearly all of the mice repeated sequences(順序) of syllables in different patterns. That’s enough to meet the definition of what scientists 27 song. But not all scientists are 28 _ that what the mice are doing is 29 singing. To prove it, the researchers must show that there’s learning involved. And, they need to __ 30 why the mice sing.
