1. Which of the following most logically completes the passage?

• A. A war between the world powers was extremely likely.
• B. World War I never would have happened.
• C. England, France, and Russia would have started the war.
• D. Austria would have started the war.

Correct answer: A

Rationale: The correct answer is A. The passage indicates that the world powers were already in a combustible situation due to complicated military alliances, making war extremely likely even without the assassination of Archduke Franz Ferdinand. Choice B is incorrect because the passage does not suggest that World War I would never have happened. Choice C is incorrect as it specifically names the countries that would have started the war, which is not supported by the passage. Choice D is also incorrect as the passage does not solely attribute the war's start to Austria.

2. Identify the genre of writing in the following brief passage: I am asking each department supervisor to identify the advantages of reconfiguring our internal accounting system. Indicate to me by next Friday if you feel this change would improve the DPD program. Which of the following genres of writing does the passage represent?

• A. Literary
• B. Professional
• C. Colloquial
• D. Scientific

Correct answer: B

Rationale: The passage represents professional writing because it is formal, work-related communication involving a request for input on a specific business-related matter. The passage's focus on internal accounting system reconfiguration and improvement of a specific program aligns with professional communication in a workplace setting. Choices A, C, and D are incorrect: A) 'Literary' writing typically focuses on creative expression and storytelling, which is not evident in this passage; C) 'Colloquial' writing is informal and conversational, unlike the formal tone of the passage; D) 'Scientific' writing involves research, data analysis, and objective facts, which are not present in the passage.

3. Microfilaments and microtubules are both components of the cytoskeleton, but they have different functions. Which of these describes microfilaments?

• A. Provide structural support and shape
• B. Facilitate cell movement and contraction
• C. Form the mitotic spindle during cell division
• D. Transport materials within the cell

Correct answer: A

Rationale: Microfilaments are thin, solid rods made of the protein actin and are primarily responsible for providing structural support to the cell and determining its shape. While they also play a role in cell movement, their main function is related to maintaining the structural integrity of the cell. Choice B, 'Facilitate cell movement and contraction,' describes microtubules, which are responsible for facilitating cell movement, providing structural support, and aiding in cell division. Choice C, 'Form the mitotic spindle during cell division,' specifically refers to the function of microtubules in forming the mitotic spindle. Choice D, 'Transport materials within the cell,' is characteristic of microtubules that are involved in intracellular transport of organelles and materials within the cell.

4. What is the technical term for the free edges of your fingernails and toenails?

• A. Lunula (The lunula is the white crescent moon shape at the base of the nail)
• B. Matrix (The matrix is the area under the nail where new nail cells are produced)
• C. Hyponychium (This is the skin under the free edge of the nail)
• D. Free edge

Correct answer: C

Rationale: The correct answer is C, hyponychium. The hyponychium is the skin under the free edge of the nail, responsible for sealing the nail to the fingertip and protecting the nail bed from bacteria and debris. The lunula (choice A) refers to the white crescent moon shape at the base of the nail. The matrix (choice B) is the area under the nail where new nail cells are produced. The free edge (choice D) is the part of the nail that extends beyond the fingertip or toe.

5. What is the pathway of oxygenated blood from the lungs?

• A. Lungs to the left atrium, through the mitral valve into the left ventricle, pumped into the aorta upon contraction, then dispersed to tissues via a network of arteries and capillaries
• B. Lungs to the right atrium, through the mitral valve into the right ventricle, pumped into the aorta upon contraction, then dispersed to tissues via a network of arteries and veins
• C. Lungs to the left atrium, directly to the right aorta, then dispersed to tissues via a network of arteries and capillaries
• D. Lungs to the left atrium, through the septal valve, stored in the left ventricles, then dispersed to tissues via a network of arteries and capillaries

Correct answer: A

Rationale: The correct pathway of oxygenated blood from the lungs is as follows: Oxygenated blood travels from the lungs to the left atrium, then passes through the mitral valve into the left ventricle. From there, it is pumped into the aorta upon contraction of the heart and is then dispersed to various tissues throughout the body via a network of arteries and capillaries. Choice B is incorrect as it incorrectly mentions the right atrium and ventricle, which are associated with deoxygenated blood. Choice C is incorrect as it mentions a direct connection to the right aorta, which does not exist in the circulatory system. Choice D is incorrect as it refers to the septal valve (which is not anatomically correct) and storing blood in the left ventricle, which does not occur in the normal circulation of blood.
