1. Which of the following, if true, would most seriously undermine the explanation proposed by the author in Passage I, third paragraph?

A. An instance of lethal force in self-defense is not absolutely absolved from blame. The law takes into account the necessary use of force at the time it is committed.
B. An individual who uses necessary defense under lethal force is in direct compliance with the law under most circumstances.
C. Lethal force in self-defense should not be forgiven in all cases for the peace of mind of the primary victim.
D. The use of lethal force is not evaluated based on the intent of the user, but rather the severity of the primary attack that warranted self-defense.

Correct answer: A

Rationale: The correct answer is A because the author in Passage I discusses the concept of lethal force in self-defense being justified and absolved from blame when used as a last resort to prevent severe harm or death. Choice A undermines this by stating that an instance of lethal force in self-defense is not absolutely absolved from blame and highlights that the law considers the necessary use of force at the time it is committed. This challenges the absolute justification of such actions and would seriously undermine the author's argument. Choice B is incorrect because compliance with the law does not necessarily address the justification and absolution of lethal force. Choice C is incorrect as forgiving lethal force in all cases is not the focus of the author's argument. Choice D is incorrect because the intent of the user is a crucial factor in evaluating the use of lethal force, contrary to what is stated.

2. Which of the answer choices gives the best definition of the underlined word in the following sentence? 'Finlay flatly refused to take part in the piano recital, so his parents had to cajole him with the promise of a trip to his favorite toy store.'

A. Prevent
B. Threaten
C. Insist
D. Coax

Correct answer: D

Rationale: In this context, 'cajole' means to persuade someone by using flattery or promises, which is best represented by 'coax.' 'Prevent' (choice A) means to stop something from happening, 'threaten' (choice B) means to communicate an intention to harm, and 'insist' (choice C) means to demand something forcefully, so these choices do not fit the context of persuading with flattery or promises.

3. What is the function of the endocrine system?

A. To protect the body from infection
B. To release digestive enzymes
C. To break down food
D. To regulate the sleep-wake cycle

Correct answer: B

Rationale: The correct answer is B. The endocrine system releases hormones that regulate various functions, including metabolism and growth. It is responsible for producing and releasing hormones that control processes such as metabolism, growth, and development. The digestive enzymes are released by the digestive system, not the endocrine system. Choices A, C, and D are incorrect because protecting the body from infection is primarily the role of the immune system, breaking down food is the function of the digestive system, and regulating the sleep-wake cycle is controlled by the circadian rhythm which is mainly influenced by the brain's hypothalamus and not the endocrine system.

4. Which of the following is a primary source?

A. A critic's summary of a book on Abraham Lincoln.
B. A peer-reviewed scientific journal's table of contents.
C. A gene splicing study report with data.
D. A news article quoting research into curing cancer.

Correct answer: C

Rationale: The correct answer is C. A gene splicing study report with data is a primary source because it provides original research findings. In contrast, choice A is a secondary source as it involves a critic's interpretation of a book. Choice B, the table of contents of a peer-reviewed scientific journal, is not a primary source but a tertiary source, providing a summary of articles. Choice D, a news article quoting research, is a secondary source that presents information based on primary sources rather than the original research itself.

5. How do spindle fiber dynamics and microtubule attachment regulate cell cycle checkpoints?

A. Misaligned chromosomes fail to attach to microtubules, triggering a delay in anaphase onset.
B. The presence of unattached kinetochores on the centromeres sends a signal to pause cell cycle progression.
C. Microtubule instability and rapid depolymerization lead to the activation of checkpoint proteins.
D. All of the above.

Correct answer: D

Rationale: A) Misaligned chromosomes fail to attach to microtubules, triggering a delay in anaphase onset: Proper attachment of chromosomes to spindle fibers is essential for accurate segregation of genetic material during cell division. Misaligned chromosomes that fail to attach to microtubules can lead to delays in anaphase onset, allowing the cell to correct errors before proceeding with division. B) The presence of unattached kinetochores on the centromeres sends a signal to pause cell cycle progression: Kinetochores at the centromeres help attach chromosomes to spindle fibers. When kinetochores are unattached or improperly attached to microtubules, they signal the cell to pause cell cycle progression, ensuring proper chromosome alignment before division. C) Microtubule instability and rapid depolymerization lead to the activation of checkpoint proteins: While microtubule dynamics are crucial for cell division, microtubule instability and rapid depolymerization can disrupt chromosome attachment. However, this mechanism is not directly related to the activation of cell cycle checkpoint proteins, making this statement incorrect. Therefore, choices A and B accurately describe how spindle fiber dynamics and microtubule attachment regulate cell cycle checkpoints, making option D the correct answer.
