1. Fraternal twins are ____________.
- A. genetically identical
- B. no more alike than ordinary siblings
- C. less common than other types of multiple offspring
- D. less likely with each additional birth
Correct answer: B
Rationale: The correct answer is B. Fraternal twins are no more alike than ordinary siblings because they share about 50% of their genes, just like other siblings. Choice A is incorrect as fraternal twins are not genetically identical. Choice C is incorrect as fraternal twins are actually the most common type of multiple offspring. Choice D is incorrect as the likelihood of fraternal twins is not affected by the number of births a mother has had.
2. Dr. Dias's research shows that the death of a spouse in old age is correlated with a decline in the surviving partner's physical health. Which conclusion is supported by this study?
- A. The death of a spouse causes a decline in the surviving partner's physical health.
- B. The death of a spouse is related to a decline in the surviving partner's physical health.
- C. A decline in a surviving partner's physical health can cause the death of a spouse.
- D. A third variable, such as memory loss, causes a surviving partner's decline in physical health following the death of a spouse.
Correct answer: B
Rationale: Dr. Dias's research findings indicate a correlation between the death of a spouse and a decline in the surviving partner's physical health. This correlation suggests a relationship between the two variables, but it does not necessarily imply a direct cause-and-effect relationship. Therefore, the correct conclusion supported by this study is option B - 'The death of a spouse is related to a decline in the surviving partner's physical health.' Option A is too direct in its causation claim, which is not proven by correlation alone. Option C reverses the cause and effect relationship suggested by the research. Option D introduces an unrelated third variable, which is not supported by the study's findings.
3. Prenatally malnourished babies frequently __________.
- A. reject breast milk
- B. have enlarged hearts
- C. catch respiratory illnesses
- D. have a higher-than-average birth weight
Correct answer: C
Rationale: Prenatally malnourished babies frequently catch respiratory illnesses. Malnourished babies have weakened immune systems, making them more susceptible to illnesses such as respiratory infections. This is a common consequence that is observed in babies who did not receive adequate nutrition during the prenatal period. Choices A, B, and D are incorrect. While malnourished babies may have feeding challenges, rejecting breast milk is not a common consequence. Enlarged hearts are not typically associated with prenatal malnutrition, and having a higher-than-average birth weight is unlikely in malnourished babies.
4. Among preschoolers, __________ contributes to gains in emotional self-regulation.
- A. permissive child rearing
- B. authoritarian child rearing
- C. language
- D. family size
Correct answer: C
Rationale: Corrected Rationale: Language development plays a crucial role in emotional self-regulation in preschoolers. It enables children to express and manage their emotions effectively. Choices A and B, permissive and authoritarian child rearing styles, focus more on the parenting approach rather than the child's intrinsic development. Family size, as mentioned in choice D, does not directly contribute to gains in emotional self-regulation.
5. Tiffany is a small-for-date baby. This means she __________.
- A. was born several weeks or more before her due date
- B. was born below her expected weight considering the length of the pregnancy
- C. will probably have much less serious problems than a preterm infant
- D. may have difficulties in infancy but will outgrow them by the preschool years
Correct answer: B
Rationale: A small-for-date baby, also known as a small-for-gestational-age (SGA) baby, is a baby who is born below their expected weight considering the length of the pregnancy. This can be due to various factors including issues with growth restriction in the womb. Being small-for-date is different from being preterm (born prematurely) and does not necessarily mean that the baby was born early. Choice A is incorrect because being small-for-date does not specifically indicate being born several weeks or more before the due date. Choice C is incorrect because being small-for-date does not guarantee fewer problems than a preterm infant, as each baby's health outcomes can vary. Choice D is incorrect because while small-for-date babies may have initial difficulties, it does not guarantee that these issues will be outgrown by the preschool years.
