1. In an investigation of over 120,000 New York City births, babies born even 1 to 2 weeks early __________ than children who experienced a full-length prenatal period.

• A. showed lower reading and math scores at a third-grade follow-up
• B. were less likely to suffer from childhood obesity
• C. were less likely to suffer from neurological impairments
• D. showed higher language and social/emotional scores in early childhood

Correct answer: A

Rationale: In the investigation of over 120,000 New York City births, babies born even 1 to 2 weeks early showed lower reading and math scores at a third-grade follow-up compared to children who experienced a full-length prenatal period. This suggests that being born slightly premature can have an impact on cognitive development, leading to educational challenges later on. Choices B, C, and D are incorrect because the study specifically highlighted lower reading and math scores, not a reduced likelihood of suffering from childhood obesity or neurological impairments, or improved language and social/emotional scores in early childhood.

2. Mounting evidence suggests that __________ is a major contributor to SIDS.

• A. impaired brain functioning
• B. higher-than-average birth weight
• C. organized and patterned sleep behavior
• D. a family history of chromosomal abnormalities

Correct answer: A

Rationale: Impaired brain functioning is a major contributor to Sudden Infant Death Syndrome (SIDS). Research has shown that abnormalities in the brainstem, which controls automatic functions like breathing and heart rate, can play a role in SIDS cases. As such, mounting evidence suggests that compromised brain functioning is a significant factor in the occurrence of SIDS. Choices B, C, and D are incorrect. Higher-than-average birth weight, organized and patterned sleep behavior, and a family history of chromosomal abnormalities are not identified as major contributors to SIDS according to the provided information.

3. Which country does not rank well on any key measure of children's health and well-being?

• A. Sweden
• B. Spain
• C. Australia
• D. The United States

Correct answer: D

Rationale: The United States is the correct answer as it ranks poorly in measures of children's health and well-being compared to other developed nations. According to the extract provided, the United States does not perform well in this aspect. Choices A, B, and C are incorrect as there is no information provided suggesting that Sweden, Spain, or Australia do not rank well on key measures of children's health and well-being.

4. By using which method of assignment of participants to treatment conditions, investigators increase the chances that participants' characteristics will be equally distributed across treatment groups?

• A. sequential
• B. random
• C. systematic
• D. correlational

Correct answer: B

Rationale: By using random assignment of participants to treatment conditions, investigators increase the chances that participants' characteristics will be equally distributed across treatment groups. Random assignment helps reduce the likelihood of bias in the selection process and ensures that any differences between groups are due to the treatment and not pre-existing group differences. Sequential, systematic, and correlational assignment methods do not provide the same level of assurance in distributing participants' characteristics equally across treatment groups.

5. What is the function of the corpus luteum?

• A. is where fertilization usually takes place
• B. secretes hormones that prepare the lining of the uterus to receive a fertilized ovum
• C. is one of two long, thin structures that lead to the hollow, softly lined uterus
• D. is one of two walnut-sized organs located deep inside a woman's abdomen

Correct answer: B

Rationale: The correct answer is B. The corpus luteum is a temporary endocrine structure in the ovary that forms after ovulation. It secretes hormones, particularly progesterone, which help prepare the uterine lining for possible implantation of a fertilized ovum. This process is crucial for maintaining a potential pregnancy. Choices A, C, and D are incorrect. Choice A is inaccurate as fertilization typically occurs in the fallopian tubes. Choice C describes the fallopian tubes, not the corpus luteum. Choice D refers to the ovaries, not specifically the corpus luteum.
