1. Lily weighed 8 pounds and was 21 inches long at birth. She was __________ than the average baby.

• A. heavier but shorter
• B. heavier and longer
• C. lighter but longer
• D. lighter and shorter

Correct answer: B

Rationale: Lily weighed 8 pounds and was 21 inches long at birth. Being both heavier and longer than average babies typically are at birth, Lily would be considered heavier and longer compared to the average baby. This makes choice B, 'heavier and longer,' the correct answer. Choices A, C, and D are incorrect because Lily was not shorter or lighter than the average baby at birth.

2. Ethnographies reveal that immigrant parents view __________ as the surest way to improve life chances.

• A. learning English
• B. education
• C. close ties to an ethnic community
• D. moving into an urban area

Correct answer: B

Rationale: Ethnographies reveal that immigrant parents prioritize education as the surest way to improve life chances for their children. While learning English is important for integration, education is considered the key for better opportunities and success in the long term. Close ties to an ethnic community can provide support but may not directly lead to improved life chances. Moving into an urban area is not highlighted in the context of immigrant parents' views on improving life chances through their children's development.

3. By age 2, children __________.

• A. take turns in face-to-face interaction
• B. can infer a speaker's indirectly expressed intention
• C. adjust their speech to fit the age of their listeners
• D. adjust their speech to fit the social status of their listeners

Correct answer: C

Rationale: By age 2, children are capable of adjusting their speech to fit the age of their listeners, showing early social cognition. Choice A is incorrect because taking turns in face-to-face interaction typically develops later in childhood. Choice B is incorrect as the ability to infer a speaker's indirectly expressed intention is a more advanced skill not typically seen at age 2. Choice D is also incorrect as children at age 2 are not developmentally ready to adjust their speech based on the social status of their listeners.

4. Which of the following is the best available predictor of infant survival and healthy development?

• A. Birth length
• B. Combined Apgar score
• C. Delivery date
• D. Birth weight

Correct answer: D

Rationale: The correct answer is 'Birth weight.' Birth weight is a crucial indicator of an infant's chances of survival and well-being. Low birth weight is associated with various health risks and developmental challenges. Birth length (choice A) is not as significant in predicting infant outcomes as birth weight. The Combined Apgar score (choice B) is a measure of the newborn's health status at birth, not a predictor of long-term survival and development. Delivery date (choice C) is important for determining gestational age but is not as directly related to infant survival and healthy development as birth weight.

5. Liz is 36 weeks pregnant. A rise in her baby's heart rate is probably followed within five seconds by __________.

• A. a burst of motor activity
• B. a period of sleep
• C. a rise in Liz's heart rate
• D. a drop in Liz's body temperature

Correct answer: A

Rationale: A rise in the baby's heart rate during pregnancy is usually followed within five seconds by a burst of motor activity. This indicates that the baby is responding to stimuli and is an important sign of healthy fetal development. A period of sleep, a rise in Liz's heart rate, or a drop in Liz's body temperature are not typically immediate responses to changes in the baby's heart rate. Sleep is less likely to be a direct response to changes in heart rate, Liz's heart rate is independent of the baby's heart rate changes, and a drop in Liz's body temperature is not a common immediate response to fetal heart rate changes.
