1. Which of the following is the greatest value?

• A. 43 ÷ 55
• B. 7 ÷ 5
• C. 0.729
• D. 73%

Correct answer: B

Rationale: To determine the greatest value among the choices, you need to convert all options to a common format. In this case, converting fractions to decimals will help compare them. When 7 ÷ 5 is calculated, it equals 1.4, which is greater than 0.729 (choice C) and 0.78 (choice A when rounded). The percentage 73% (choice D) is equivalent to 0.73, making 7 ÷ 5 the largest value. Therefore, the correct answer is B. Choice A is smaller than B, as 43 ÷ 55 equals approximately 0.78. Choice C is smaller than B, as 0.729 is less than 1.4. Choice D is smaller than B, as 73% is equal to 0.73, which is less than 1.4.

2. Where does sperm production occur?

• A. Prostate gland
• B. Seminal vesicles
• C. Scrotum
• D. Seminiferous tubules

Correct answer: D

Rationale: Sperm production occurs in the seminiferous tubules within the testes. These tubules are responsible for spermatogenesis, the process of sperm creation. The prostate gland and seminal vesicles contribute to seminal fluid production, while the scrotum houses the testes but does not produce sperm. Therefore, choices A, B, and C are incorrect as they are not sites for sperm production.

3. Veronica has to create the holiday schedule for the neonatal unit at her hospital. 35% of her staff will be unavailable during the holidays, and of the remaining staff, only 20% are certified to work in the neonatal unit. What percentage of the total staff is certified and available to work?

• A. 7%
• B. 13%
• C. 65%
• D. 80%

Correct answer: B

Rationale: The correct answer is 13%. To find the percentage of the total staff that is certified and available to work, we first calculate the percentage of staff available, which is 100% - 35% = 65%. Then, we find the percentage of the available staff that is certified, which is 20% of 65% = 0.20 × 0.65 = 0.13, or 13%.

4. Which of the following statements regarding heart valves is correct?

• A. The atrioventricular valves lie between the atria and the ventricles.
• B. The pulmonary semilunar valve lies between the right ventricle and the pulmonary trunk.
• C. The atrioventricular valves prevent backflow into the atria when the ventricles contract.
• D. All of the above

Correct answer: D

Rationale: All of the statements are correct regarding heart valves. Choice A is accurate as the atrioventricular valves indeed lie between the atria and the ventricles. Choice B correctly identifies the location of the pulmonary semilunar valve. Choice C is true as the atrioventricular valves do prevent backflow into the atria during ventricular contraction. Therefore, selecting 'All of the above' as the correct answer is appropriate as all statements are accurate.

5. 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.
