Which would be an appropriate way to apply research on fetal brain activity?
◦ A mother-to-be plays music and speech loudly through a speaker next to her abdomen, to promote development of the auditory cortex.
◦ A mother-to-be uses a "pregaphone" to promote bonding with her unborn child.
◦ A mother-to-be plays classical music in her home more frequently to encourage development.
◦ A mother-to-be watches Spanish-language television so that her child will learn a second language more easily.
