Correct Answer: A

Rationale: Pregnant women are wise to avoid eating long-lived predatory fish, which are heavily contaminated with mercury. Mercury is a known teratogen, meaning it can negatively impact the development of the fetus and lead to birth defects. It is recommended that pregnant women choose fish with lower levels of mercury to reduce potential risks to the baby's health. Choices B, C, and D are incorrect because lead, polychlorinated biphenyls, and radiation are not typically found in fish at levels that pose significant risks to pregnant women and the developing fetus.

Correct Answer: A

Rationale: Dr. Torrez's belief about conflicts between biological drives and social expectations influencing a person's ability to learn, get along with others, and cope with anxiety aligns with the psychoanalytic perspective. This perspective, developed by Sigmund Freud, focuses on the unconscious mind, early childhood experiences, and the resolution of inner conflicts as important factors in shaping personality and behavior. The other choices are incorrect because psychosocial theory, cognitive-developmental theory, and social learning theory do not specifically focus on conflicts between biological drives and social expectations as central to understanding human behavior and development.

Correct Answer: A

Rationale: Vygotsky's emphasis on culture and social experience did not lead him to neglect the biological side of development. Instead, he believed that biological factors and social influences interact to shape cognitive development. Choice A is correct because it reflects Vygotsky's view that biological factors and social experiences work together in cognitive development. Choices B, C, and D are incorrect as Vygotsky's emphasis was not on overemphasizing heredity, focusing solely on independent efforts of children, or placing too much emphasis on children's capacity to shape their own development.

Correct Answer: B

Rationale: The correct answer is B: eye-blink. The eye-blink reflex is the one that protects an infant from strong stimulation by causing them to quickly shut their eyes in response to sudden bright light or a loud noise. This reflex helps to safeguard the infant's sensitive eyes from potential harm. The Moro reflex (choice A) is the startle reflex, the sucking reflex (choice C) helps with feeding, and the palmar grasp reflex (choice D) is when the infant's fingers close around an object placed in their hand; none of these reflexes specifically protect the infant from strong stimulation.

Correct Answer: C

Rationale: Small-for-date infants more often show evidence of brain damage than preterm infants. This can be attributed to factors such as intrauterine growth restriction and poor nutrition during pregnancy, which can affect the development of the baby's brain. Choices A, B, and D are incorrect because there is no evidence to support that small-for-date infants catch fewer infections, are less likely to die, or have higher intelligence tests compared to preterm infants.
