1. According to __________ theory, children learn primarily through modeling.

• A. reinforcement
• B. operant conditioning
• C. social learning
• D. classical conditioning

Correct answer: C

Rationale: According to social learning theory, children primarily learn through modeling, observation, and imitation of others. This theory emphasizes the importance of cognitive processes in learning, as opposed to only focusing on direct reinforcement or punishment. Social learning theory was developed by psychologist Albert Bandura and is a key theory in the field of child development. Choice A, reinforcement, is incorrect as it refers to the process of strengthening a behavior through rewards or punishments. Choice B, operant conditioning, is also incorrect as it is a learning process that involves reinforcement and punishment to shape behavior. Choice D, classical conditioning, is not the correct answer as it involves learning through association between stimuli.

2. Which mother is most likely to have had inadequate prenatal care?

• A. Lupe, age 25
• B. Marissa, age 32
• C. Rotunda, age 16
• D. Janette, age 40

Correct answer: C

Rationale: Rotunda, age 16, is the most likely to have had inadequate prenatal care due to her young age and possibly limited access to healthcare resources and support. Adolescents are at higher risk for inadequate prenatal care compared to older mothers due to various factors such as lack of awareness, financial constraints, and inconsistent health behaviors. Young mothers may face challenges in seeking proper prenatal care due to reasons like lack of knowledge, fear of judgment, or limited financial means. Older mothers like Lupe, Marissa, and Janette are less likely to have inadequate prenatal care compared to a younger mother like Rotunda, as they may have more access to resources, experience, and support systems.

3. In females, the twenty-third pair of chromosomes is labeled as __________.

• A. an autosome
• B. dizygotic
• C. XX
• D. XY

Correct answer: C

Rationale: In females, the twenty-third pair of chromosomes is indeed labeled as XX. This pair of chromosomes determines the biological sex of females. Choice A, 'an autosome,' is incorrect as autosomes refer to the non-sex chromosomes. Choice B, 'dizygotic,' is incorrect as it relates to twins. Choice D, 'XY,' is incorrect as it represents the chromosome pair found in males.

4. 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.

5. Three-month-old Jefferson will probably listen longer to __________ than to __________.

• A. pure tones; voices
• B. pure tones; noises
• C. human speech; nonspeech sounds
• D. a foreign language; his native language

Correct answer: C

Rationale: Three-month-old Jefferson will likely listen longer to human speech compared to nonspeech sounds because infants have a natural preference for speech sounds. This preference is believed to be attributed to their biological readiness to learn language and communicate with others. Choice A is incorrect because voices are a form of human speech, which is preferred over pure tones. Choice B is incorrect as noises do not necessarily engage infants' attention as effectively as human speech. Choice D is incorrect because Jefferson is more likely to listen longer to his native language rather than a foreign language at this early age.
