1. During pregnancy, the placenta __________.

• A. forms in the second trimester of pregnancy
• B. encloses the developing organism in amniotic fluid
• C. contains one large vein that delivers nutrients to the embryo
• D. delivers food and oxygen to the developing organism

Correct answer: D

Rationale: The placenta delivers food and oxygen to the developing organism during pregnancy. It is a temporary organ that forms in the first trimester of pregnancy. Choice A is incorrect as the placenta forms in the first trimester, not the second trimester. Choice B is incorrect as the amniotic sac, not the placenta, encloses the developing organism in amniotic fluid. Choice C is incorrect as the placenta contains blood vessels (arteries and veins) that deliver nutrients to the embryo, not just one large vein.

2. Vygotsky's emphasis on culture and social experience led him to __________.

• A. understand the interaction between biological factors and social influences in cognitive development
• B. overemphasize the role of heredity in cognitive change
• C. emphasize children's independent efforts to make sense of their world
• D. place too much emphasis on children's capacity to shape their own 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.

3. School-age children master concrete operational tasks ________.

• A. all at once
• B. gradually, in a continuum of acquisition
• C. much later than Piaget believed
• D. after they master abstract thinking

Correct answer: B

Rationale: Correct answer: School-age children master concrete operational tasks gradually, in a continuum of acquisition. Piaget's theory suggests that children develop cognitive abilities in stages, with concrete operational tasks being acquired gradually as part of this process. Choices A, C, and D are incorrect because concrete operational tasks are not typically mastered all at once, much later than Piaget believed, or necessarily after mastering abstract thinking.

4. Pregnant women are wise to avoid eating __________, which are heavily contaminated with __________.

• A. long-lived predatory fish; mercury
• B. freshwater fish; lead
• C. long-lived predatory fish; polychlorinated biphenyls
• D. freshwater fish; radiation

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.

5. In egalitarian marriages, __________.

• A. there is a clear division of roles
• B. partners share power and authority
• C. the husband is the head of the household
• D. the wife is responsible for family economic well-being

Correct answer: B

Rationale: In egalitarian marriages, the correct answer is B - partners share power and authority. This type of marriage promotes equality and balance, where both spouses have an equal say in decision-making and share responsibilities. Choice A is incorrect because egalitarian marriages aim to reduce traditional role divisions. Choice C is incorrect as it suggests a patriarchal structure, which is contrary to the principles of egalitarianism. Choice D is incorrect as it assigns a specific financial role based on gender, which goes against the idea of equal sharing in all aspects of the marriage.
