Answer:
B. Display a sense of musical phrasing
Step-by-step explanation:
This is a very interesting question that, depending on who reads it, the answer may change, especially because when it comes to babies there is not an absolute consensus about what is really going on in their brains. Besides, with the day to day advances in neuroscience there is always something new we understand (or realize we dont understand at all!) about the brain. In my case, I got to answer B just by aplying some logic:
A) "Prefer nonspeech over human speech". There are two main reasons why i think this cannot be the correct choice: first, when babies are around 7 months they start trying to imitate verbal communication of their parents, and, second, because it seems very unrealistic to say that a baby (4-7 months old) is actually prefering one way of speech over another.
C) "Prefer pieces of music with awkward breaks rather than those with pauses between phrases". This is an answer we can certainly put aside because of it subjective and demeaning way of expressing (i.e "awkward breaks").
D) "Listening to a foreign language rather than their native tongue". Again, two reasons, first the "preference" assumption, and secondly, assuming a baby would understand the difference between two diferent tongues is laughable.
B) Display a sense of musical phrasing. I would think this is the correct choice, not only because the other possible questions are clearly faulty, but also because I have encountered with multiple articles in which the music importance in the language and cognitive development of the baby is shown.
Hope this helps!
