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. Nonnormative influences are irregular and do not follow a predictable timetable.

• A. Nonnormative
• B. History-graded
• C. Age-graded
• D. Bio-historical

Correct answer: A

Rationale: The correct answer is A: Nonnormative. Nonnormative influences are events or experiences that are irregular and unique to the individual, so they do not follow a predictable timetable. These influences can include major life events like winning the lottery or experiencing a natural disaster, and they have a significant impact on a person's development. Choice B, History-graded influences, are events that are common to people of a particular generation due to historical circumstances. Choice C, Age-graded influences, are events that are typical for people of a certain age group. Choice D, Bio-historical, is not a recognized term in developmental psychology.

3. Brain growth is especially dramatic during __________, when the brain more than doubles in size.

• A. the first year
• B. the second year
• C. middle childhood
• D. adolescence

Correct answer: A

Rationale: Brain growth is especially dramatic during the first year of life when the brain more than doubles in size. This period is characterized by rapid neural development and growth. The brain doesn't double in size during the second year, making choice B incorrect. Middle childhood and adolescence do not represent periods where the brain more than doubles in size, making choices C and D incorrect, respectively.

4. According to Erikson, __________ occurs when aging adults feel they have made many wrong decisions, yet time is too short to find an alternate route to integrity.

• A. mistrust
• B. despair
• C. stagnation
• D. isolation

Correct answer: B

Rationale: According to Erikson's theory of psychosocial development, despair is the stage that aging adults face when they reflect on their life and feel they have not achieved their goals, with little time left to correct their mistakes. Mistrust (choice A) is associated with infancy, stagnation (choice C) with middle adulthood, and isolation (choice D) with young adulthood, and are not relevant to the described scenario of aging adults reflecting on their life decisions.

5. Lanugo ________.

• A. permits food and oxygen to reach the organism
• B. provides the fetus a cushion against jolts caused by the mother's movements
• C. helps regulate the fetus's body temperature
• D. helps the vernix stick to the skin

Correct answer: D

Rationale: Lanugo helps the vernix stick to the skin. Vernix is a waxy substance that covers the fetus's skin during pregnancy. Lanugo is a fine, downy hair that helps to anchor the vernix to the skin, providing protection and nourishment to the developing fetus. Choices A, B, and C are incorrect as they do not accurately describe the role of lanugo in prenatal development.
