Final answer:
The Asian woman's refusal to make eye contact while learning about prenatal care is most likely due to cultural norms.
Step-by-step explanation:
When an Asian woman refuses to make eye contact while being taught about prenatal care, it is most likely due to cultural norms. In many Asian cultures, avoiding direct eye contact is considered respectful and a sign of deference. Eye contact may be seen as intrusive or aggressive in these cultures, so the woman's behavior is likely not related to vision impairment, social anxiety, or a language barrier.
