1. During which phase of the cell cycle does cytokinesis typically occur?

• A. Interphase
• B. Mitosis
• C. Meiosis
• D. G2 phase

Correct answer: B

Rationale: Cytokinesis is the process of dividing the cytoplasm of a cell into two daughter cells after the nucleus has divided during mitosis. In the cell cycle, cytokinesis typically occurs at the end of the mitotic phase, following the separation of the duplicated chromosomes into two identical sets in the daughter nuclei. Interphase (option A) is the phase where the cell grows, carries out its normal functions, and prepares for cell division, but cytokinesis does not occur during this phase. Meiosis (option C) is a specialized type of cell division that occurs in sexually reproducing organisms to produce gametes, and cytokinesis occurs at the end of meiosis II, not meiosis I. G2 phase (option D) is the phase of the cell cycle following DNA replication in S phase and preceding mitosis, where the cell prepares for cell division, but cytokinesis occurs during mitosis, not in the G2 phase.

2. During the Civil War, the United States, still a fairly young country, was divided into the North and South on strongly felt issues. President Abraham Lincoln took a stand on the side of the North, which ultimately emerged victorious. What is the most appropriate topic sentence for the passage below?

• A. The Civil War was a war that was not easily won, but hard fought.
• B. The Civil War ended in 1865.
• C. Jefferson Davis was the President of the Confederate States.
• D. Many countries have had civil wars.

Correct answer: A

Rationale: The topic sentence sets the stage for the discussion that follows. Choice A, 'The Civil War was a war that was not easily won, but hard fought,' is the most appropriate as it introduces the theme of the challenges faced during the Civil War and the determination required for victory. Choice B, 'The Civil War ended in 1865,' is a factual statement but does not lead into the paragraph content. Choice C, 'Jefferson Davis was the President of the Confederate States,' introduces a different historical figure not central to the paragraph. Choice D, 'Many countries have had civil wars,' is a broad statement not related to the specific context of the Civil War in the United States.

3. What is the main idea conveyed in the extract?

• A. Shia hears strange noises in the dark hallway
• B. Shia is working late at the office
• C. Shia is preparing for a presentation
• D. Shia encounters a terrifying situation in the CFO's office

Correct answer: D

Rationale: The main idea conveyed in the extract is that Shia encounters a terrifying situation in the CFO's office. The passage describes Shia hearing strange noises, feeling fear, and encountering alarming events like crashes and howls. This builds tension and indicates a dangerous situation unfolding. Choices A, B, and C are incorrect as they do not capture the central theme of Shia facing a frightening encounter in the CFO's office.

4. What is the tough, fibrous tissue that connects bones at joints called?

• A. Cartilage
• B. Ligaments
• C. Tendons
• D. Fascia

Correct answer: B

Rationale: Ligaments are the tough, fibrous tissue that connects bones at joints, providing stability and support to prevent excessive movement and potential injury. Cartilage is a smooth, rubbery connective tissue that covers bone ends at joints. Tendons connect muscles to bones, enabling movement. Fascia surrounds muscles, blood vessels, and nerves, providing support and structure to these tissues. In this context, ligaments are specifically the connective tissues that bind bones together at joints, not cartilage, tendons, or fascia.

5. Which property of a substance resists a change in its shape?

• A. Density
• B. Mass
• C. Inertia
• D. Elasticity

Correct answer: D

Rationale: Elasticity refers to a material's ability to resist deformation and return to its original shape after stress is applied. It is the property that resists a change in shape. Density is the mass per unit volume of a substance. Mass is the amount of matter in an object, while inertia is the tendency of an object to resist changes in its state of motion. Viscosity, not mentioned in the question, is the resistance of a fluid to flow, not shape change.
