1. She is hopeful that her unit will make a big turnaround in the succeeding months. Which of

• A. Wonders why things are not what it used to be
• B. Finds solutions to the problems
• C. Integrate the solutions to his day-to-day activities
• D. Selects the best change strategy

Correct answer: C

Rationale: The correct answer is C: 'Integrate the solutions to his day-to-day activities.' In the given scenario, the individual is hopeful about a turnaround in their unit, indicating a desire for positive change. Option C aligns with this by suggesting that the individual is not only finding solutions to the problems (as in option B) but also integrating these solutions into their daily routines. This integration is crucial for sustained improvement and long-term success, making it the most appropriate choice among the options provided.

2. Which of the following phrases is grammatically correct and uses parallel structure?

• A. He enjoys reading, writing, and to play sports.
• B. Walking, swimming, and cooking are his favorite hobbies.
• C. He likes to read, write, and playing sports.
• D. Singing, dancing, and to travel are his passions.

Correct answer: B

Rationale: Option B uses the gerund (-ing) form for all three hobbies, achieving parallel structure.

3. Acne vulgaris, commonly known as acne, is primarily caused by

• A. Dry skin (Dry skin can worsen acne but isn't the primary cause)
• B. Clogged pores and excess oil production
• C. Bacterial infection alone (Bacteria play a role but not the sole cause)
• D. Vitamin deficiency

Correct answer: B

Rationale: The correct answer is B: 'Clogged pores and excess oil production.' Acne vulgaris, or acne, is primarily caused by a combination of factors including excess sebum (oil) production by the skin's sebaceous glands and the accumulation of dead skin cells, leading to clogged pores. This environment provides a breeding ground for acne-causing bacteria, contributing to inflammation and the formation of pimples. While factors like dry skin, bacterial infections, and even vitamin deficiencies can exacerbate acne, they are not the primary cause. Thus, B is the most accurate option for the primary cause of acne.

4. An IV drip delivers 40 drops per minute, each containing 1mg of medication. How many milligrams are administered in 3 hours (180 minutes)?

• A. 360mg
• B. 720mg
• C. 7,200mg
• D. 14,400mg

Correct answer: C

Rationale: Rationale: In this scenario, we first calculated the total number of drops administered in 3 hours by multiplying the drops per minute by the total number of minutes. Then, we converted the drops to milligrams by multiplying the total drops by the amount of medication in each drop. This method ensures an accurate calculation of the total amount of medication administered over the given time period.

5. Peppered moths in England came in two color variations – light and dark. After the Industrial Revolution, the population shifted towards more dark moths. This is an example of:

• A. Artificial selection (humans breeding for desired traits)
• B. Natural selection acting on pre-existing variation
• C. Punctuated equilibrium (rapid bursts of evolution)
• D. Lamarckism (inheritance of acquired characteristics)

Correct answer: B

Rationale: Rationale: The phenomenon of peppered moths in England shifting towards more dark moths after the Industrial Revolution is a classic example of natural selection acting on pre-existing variation. Before the Industrial Revolution, light-colored moths were better camouflaged against lichen-covered tree trunks, which were common in the environment. However, with the increase in industrial pollution, the tree trunks became darker due to soot, making dark-colored moths better camouflaged and less likely to be eaten by predators. As a result, the population shifted towards more dark moths over time. This change in the moth population was driven by the selective pressure of predation, demonstrating the process of natural selection favoring individuals with traits that provide a survival advantage in a changing environment.

6. The muscular chamber of the heart that receives blood from the body and pumps it to the lungs is the:

• A. Right atrium
• B. Left atrium
• C. Right ventricle
• D. Left ventricle

Correct answer: C

Rationale: The correct answer is C: Right ventricle. The right ventricle receives deoxygenated blood from the body and pumps it to the lungs for oxygenation. The right atrium receives deoxygenated blood from the body and passes it to the right ventricle. The left atrium receives oxygenated blood from the lungs and passes it to the left ventricle. The left ventricle then pumps oxygenated blood to the rest of the body. Understanding the flow of blood through the heart chambers is essential for grasping the functions of each chamber in the circulatory system.
