Neurobiologists Laura Cuaya, Raúl Hernández-Perez, and colleagues investigated the language detection abilities of eighteen dogs. The researchers monitored the brain activity of Bran (a border collie), Alma (a mixed breed), and other dogs while the animals listened to three recordings: one of The Little Prince being read in Spanish, the second in Hungarian, and a third made up of short, randomly selected fragments of the first two, scrambled so that they didn't resemble human speech. Each dog was familiar with either Spanish or Hungarian, but not both. The team concluded that differences in dogs' anatomical features may affect their ability to distinguish speech from nonspeech.
Which finding from the study, if true, would most directly support the team's conclusion?
The pattern of brain activity that long-headed dogs showed when hearing the scrambled recording was different from the pattern of brain activity that short-headed dogs showed when hearing the language they were accustomed to.
A
Long-headed dogs accustomed to hearing Spanish tended to show more brain activity when hearing Spanish than long-headed dogs accustomed to hearing Hungarian showed when hearing Hungarian.
B
Compared with longer-headed dogs, shorter-headed dogs showed less difference in brain activity when hearing either Spanish or Hungarian than when hearing the scrambled recording.
C
Compared with longer-headed dogs, shorter-headed dogs showed a greater difference in brain activity when hearing the language they were accustomed to than when hearing the other language.
D
