1. What is the name of the white blood cells that attack foreign invaders?
- A. Phagocytes
- B. Lymphocytes
- C. Platelets
- D. Red blood cells
Correct answer: A
Rationale: Rationale: Phagocytes are a type of white blood cell that plays a crucial role in the immune system by engulfing and digesting foreign invaders such as bacteria, viruses, and other harmful substances. They are part of the body's innate immune response and are essential for protecting the body against infections. Lymphocytes, on the other hand, are another type of white blood cell involved in the adaptive immune response, producing antibodies and coordinating immune responses. Platelets are cell fragments involved in blood clotting, while red blood cells are responsible for carrying oxygen to tissues.
2. A birthday party hat has a cone-shaped top with a radius of 5cm and a height of 12cm. What is its volume?
- A. 60 cu cm
- B. 120 cu cm
- C. 150 cu cm
- D. 180 cu cm
Correct answer: C
Rationale: Use the formula for volume of a cone: (1/3) * π * (radius)^2 * height. Substitute the values: (1/3) * π * (5cm)^2 * 12cm ≈ 150 cu cm.
3. Stephanie is often seen interacting with the medical intern during coffee breaks and after duty
- A. Formal
- B. Informal
- C. Staff
- D. Line
Correct answer: B
Rationale: The correct answer is 'B: Informal.' Stephanie's interactions with the medical intern during coffee breaks and after duty suggest a casual and friendly relationship, rather than a formal or official one. 'Informal' describes interactions that are relaxed, personal, and not bound by strict professional protocols. In contrast, 'formal' interactions would involve more structured and official communication, such as meetings or professional discussions. 'Staff' and 'line' are not relevant in this context, as they do not describe the nature of the relationship between Stephanie and the medical intern.
4. The phrase "think outside the box" encourages readers to:
- A. Follow established procedures.
- B. Be creative and find new solutions.
- C. Accept traditional ideas.
- D. Avoid making mistakes.
Correct answer: B
Rationale: The phrase emphasizes unconventional thinking and exploring new approaches.
5. The artist paints breathtaking landscapes. What is the third-person singular, present tense form of the verb "paint"?
- A. painted
- B. paints
- C. painting
- D. painter
Correct answer: B
Rationale: Verbs change depending on the subject (person) and time (tense).
6. A study finds a correlation between increased ice cream consumption and lower crime rates. What is the MOST likely explanation for this observation?
- A. Ice cream directly reduces criminal behavior.
- B. People who commit crimes eat less ice cream.
- C. A third factor, like hot weather, influences both.
- D. The study design is flawed and the connection is false.
Correct answer: C
Rationale: The most likely explanation for the correlation between increased ice cream consumption and lower crime rates is a third factor influencing both variables. In this case, hot weather could be the common factor as both ice cream consumption and crime rates tend to increase during warmer months. This scenario illustrates the importance of considering confounding variables when interpreting correlations.
