1. In an experiment, the independent variable __________.

• A. is the one the investigator expects to be influenced by another variable
• B. is the one the investigator expects to cause changes in another variable
• C. cannot be manipulated or controlled by the researcher
• D. is the number that describes how two measures are associated with each other

Correct answer: B

Rationale: In an experiment, the independent variable is the one that the investigator expects to cause changes in another variable. It is the factor that is deliberately manipulated or changed by the researcher to observe its effects on the dependent variable. The purpose of manipulating the independent variable is to study its impact on the outcome, allowing researchers to establish cause-and-effect relationships in their investigations. Choice A is incorrect because the independent variable is not influenced but rather influences another variable. Choice C is incorrect as the independent variable is intentionally manipulated by the researcher. Choice D is incorrect as it refers to a different concept unrelated to the independent variable in an experiment.

2. In the United States, the second leading cause of neonatal mortality is __________, which is largely preventable.

• A. malnutrition
• B. physical abnormality
• C. low birth weight
• D. sudden infant death syndrome

Correct answer: C

Rationale: The second leading cause of neonatal mortality in the United States is low birth weight, which is largely preventable through proper prenatal care, nutrition, and health interventions. Low birth weight infants are at higher risk for various health complications and mortality, making it an important issue to address in maternal and child health programs. Malnutrition (choice A) can contribute to low birth weight but is not the direct cause of neonatal mortality. Physical abnormality (choice B) can be a factor in some cases but is not the second leading cause overall. Sudden infant death syndrome (choice D) refers to unexplained deaths of seemingly healthy babies and is not related to low birth weight as a leading cause of neonatal mortality.

3. What is a major strength of the clinical interview?

• A. Makes comparing individuals' responses very easy
• B. Can provide a large amount of information in a fairly brief period
• C. Is directed toward understanding a culture or distinct social group
• D. Allows researchers to see the behavior of interest as it occurs in natural settings

Correct answer: B

Rationale: The major strength of the clinical interview is that it can provide a large amount of information in a fairly brief period. This allows researchers to gather detailed data about an individual's thoughts, feelings, and behaviors efficiently. Choice A is incorrect because the clinical interview focuses on gathering information from individuals rather than comparing their responses. Choice C is incorrect as clinical interviews are primarily aimed at understanding individuals rather than cultures or social groups. Choice D is incorrect as it describes a strength of naturalistic observations, not clinical interviews.

4. In egalitarian marriages, __________.

• A. there is a clear division of roles
• B. partners share power and authority
• C. the husband is the head of the household
• D. the wife is responsible for family economic well-being

Correct answer: B

Rationale: In egalitarian marriages, the correct answer is B - partners share power and authority. This type of marriage promotes equality and balance, where both spouses have an equal say in decision-making and share responsibilities. Choice A is incorrect because egalitarian marriages aim to reduce traditional role divisions. Choice C is incorrect as it suggests a patriarchal structure, which is contrary to the principles of egalitarianism. Choice D is incorrect as it assigns a specific financial role based on gender, which goes against the idea of equal sharing in all aspects of the marriage.

5. In the __________ period, teratogens rarely have any impact.

• A. germinal
• B. embryonic
• C. fetal
• D. prenatal

Correct answer: A

Rationale: In the germinal period of prenatal development, which lasts for about the first two weeks after fertilization, the developing organism is a zygote that has not yet implanted in the uterus. During this period, teratogens rarely have any impact because essential implantation and early cellular division processes are occurring. Teratogens are more likely to have significant effects during the later embryonic and fetal periods of development. Therefore, the correct answer is A. Choice B, embryonic period, is incorrect because teratogens have a higher likelihood of impacting development during this period. Choice C, fetal period, is also incorrect as teratogens can impact development during this stage as well. Choice D, prenatal, is a broad term encompassing the entire period of development from conception to birth and is not a specific developmental stage where teratogens have a minimal impact.
