Question

According to the passage, _____________________________________.

• A. The researchers found that the fetuses responded to their own mother's voice with heart-rate deceleration and to the stranger's voice with heart-rate acceleration.
• B. The findings of the research suggest that the foundations for speech perception and language acquisition are laid after birth.
• C. Dr. Kisilevsky's research proves that the 'preference/recognition' of voices by the fetuses begins before birth.
• D. Dr. Kisilevsky's research proves that newborns prefer to listen to their own mother's voice than to listen to that of a female stranger and will even change their behavior to elicit their mother's voice.

Answer 1

Answer: (C)

The passage talks about Dr. Kisilevsky's research which proves that voice recognition of a fetus begins before its birth. The passage also mentions the previous research (not that of Dr.Kisilevsky) on infant development which demonstrates that newborns prefer to listen to their own mother's voice than to that of a female stranger. Options B and C are not mentioned in the passage. Between A and D, D is the correct answer as option A says that the previous research was conducted by Dr.Kisilevsky, which is incorrect.
