1. If having a gene for Parkinson's disease guarantees that Parkinson's disease will develop, the gene is a ________.

Correct answer: B

Rationale: The correct answer is B: necessary cause. A necessary cause is an essential factor for the disorder to occur. In this scenario, if having a gene for Parkinson's disease guarantees the development of the disease, then the gene is a necessary cause. Choice A, 'risk factor,' implies an increased likelihood of developing the disease but does not indicate certainty. Choice C, 'sufficient cause,' indicates that the gene alone can bring about the disease, which is not necessarily true in this context. Choice D, 'contributory cause,' suggests that the gene plays a part in causing the disease but is not essential for its development.

2. Nearly all adults who were children living in Saigon when the U.S. armed forces left Vietnam in 1975 report that their lives were changed by those events. This exemplifies which of the following?

Correct answer: C

Rationale: The correct answer is C. This scenario exemplifies a critical period in development. Critical periods are specific times in an individual's life when certain events have a profound impact on their development. In this case, the events surrounding the departure of the U.S. armed forces from Saigon in 1975 had a lasting influence on the children living there at that time. Choices A, B, and D are incorrect. Normative age-graded influence refers to events that are common to people of a particular age group, the social clock relates to the culturally preferred timing of social events, and a sensitive period is a time when an individual is more susceptible to environmental influences but does not result in lifelong consequences as with critical periods.

3. The baby coos and the mom smiles, so the baby coos again to get mom to smile again. Piaget would say that this action is an example of?

Correct answer: C

Rationale: The correct answer is C: Secondary circular reactions. Secondary circular reactions are repeated actions that infants engage in to trigger a response from the environment, such as the baby cooing to make the mom smile. This behavior is characterized by a focus on the external environment and the repetition of actions to achieve a desired response. Choices A, B, and D are incorrect. Reflexes (choice A) are automatic, involuntary responses to a stimulus, while primary circular reactions (choice B) involve the repetition of actions primarily for the infant's own enjoyment rather than to elicit a response from the environment. Tertiary circular reactions (choice D) refer to the experimentation with new behaviors and variations in the way the infant interacts with the environment.

4. Normal human cells have ________.

Correct answer: A

Rationale: The correct answer is A. Normal human cells have twenty-two chromosome pairs and one pair of sex chromosomes. This adds up to a total of 46 chromosomes. Choice B is incorrect as it mentions twenty-one trisomy chromosome pairs, which is not a characteristic of normal human cells. Choice C is also incorrect as it states twenty-one chromosome pairs and two trisomy chromosome pairs, which is not accurate for normal human cells. Choice D is incorrect as it mentions twenty-three chromosome pairs, which is not the correct number for normal human cells.

5. Cortisol is a hormone that ________.

Correct answer: C

Rationale: Cortisol is a hormone produced by the adrenal gland that mobilizes the body to deal with stress. Therefore, choice C is the correct answer. Choices A and B are incorrect as they inaccurately describe the origin and function of cortisol. Choice D is also incorrect as it describes the action of a different type of substance, not cortisol.
