1. Which of the following is the MOST common symptom of angina pectoris, a condition related to insufficient blood flow to the heart?

• A. Fever and chills.
• B. Chest pain or discomfort.
• C. Sudden onset of severe shortness of breath.
• D. Numbness or tingling in the extremities.

Correct answer: B

Rationale: Chest pain or discomfort is the most common symptom of angina pectoris. This pain is often described as squeezing, pressure, heaviness, tightness, or pain in the chest. Fever and chills, sudden onset of severe shortness of breath, and numbness or tingling in the extremities are not typical symptoms of angina pectoris. The pain associated with angina is usually triggered by physical or emotional stress and typically subsides with rest or medication, distinguishing it from other conditions.

2. A spring with a spring constant of 100 N/m is stretched 0.2 m from its equilibrium position. What is the potential energy stored in the spring?

• A. 2 J
• B. 4 J
• C. 8 J
• D. 20 J

Correct answer: C

Rationale: The potential energy stored in a spring is given by the formula \(PE = \frac{1}{2}kx^2\), where \(k\) is the spring constant and \(x\) is the displacement from the equilibrium position. Substituting the given values, we get \(PE = \frac{1}{2} \times 100 \times (0.2)^2 = 8\) J.

3. Which hormone is responsible for milk production in the breasts after childbirth?

• A. Estrogen
• B. Prolactin
• C. Oxytocin
• D. Relaxin

Correct answer: B

Rationale: Prolactin is the hormone responsible for milk production in the breasts after childbirth. It is produced by the pituitary gland and stimulates the mammary glands to produce milk. Estrogen aids in the development of breast tissue during pregnancy but is not directly involved in milk production. Oxytocin is responsible for milk ejection during breastfeeding, while Relaxin helps relax uterine muscles during pregnancy but is not directly linked to milk production.

4. The plump old white cat basked in the warm sunlight. Which of the following options correctly punctuates the above?

• A. The plump, old, white cat basked in the warm sunlight.
• B. The plump, old, white, cat basked in the warm sunlight.
• C. The plump, old white cat basked in the warm sunlight.
• D. The plump old white cat, basked in the warm sunlight.

Correct answer: A

Rationale: The correct answer is A: 'The plump, old, white cat basked in the warm sunlight.' Commas should be used to separate coordinate adjectives describing the cat. In this sentence, 'plump,' 'old,' and 'white' are coordinate adjectives, each providing distinct information about the cat. Option B incorrectly places a comma after 'white,' creating a nonessential element. Option C lacks commas to separate the coordinate adjectives. Option D incorrectly places a comma after 'cat,' causing a punctuation error.

5. Arrange the following sentences into a chronological paragraph on preparing for the basketball season: There is a myriad of preparation to be completed before the basketball season begins. First, a player must ensure they are in the physical shape required to play an aerobic game such as basketball. This could include lifting weights, short- and long-distance running, and completing ball-handling drills. Additionally, players must ensure they are in good academic standing. Lastly, players can prepare for the basketball season by purchasing the necessary equipment, including proper shoes and socks.

• A. First, a player must ensure they are in physical shape.
• B. Next, players should lift weights and complete drills.
• C. Then, players should ensure they are in good academic standing.
• D. Finally, players should purchase necessary equipment.

Correct answer: C

Rationale: The correct chronological order for the sentences is as follows: First, a player must ensure they are in the physical shape required for basketball. Next, they should engage in physical activities like lifting weights, running, and completing drills. Then, players need to ensure they are in good academic standing to participate. Finally, players can prepare by purchasing the necessary equipment. Choice C, 'Then, players should ensure they are in good academic standing,' is the correct answer as it aligns with the sequence of steps required for preparing for the basketball season. Choices A, B, and D are incorrect because they do not follow the chronological order presented in the paragraph.
