Anatomy
1. The measurable electrical activity of the brain is recorded by a:
- A. CAT scan
- B. MRI scan
- C. Electroencephalogram (EEG)
- D. X-ray
Correct answer: C
Rationale: The correct answer is C: "Electroencephalogram (EEG)". An EEG is a non-invasive test that measures the electrical activity of the brain by placing electrodes on the scalp. It is specifically designed to record brain wave patterns, making it a valuable tool in diagnosing conditions such as epilepsy, sleep disorders, and brain injuries. A CAT scan (A) and MRI scan (B) are imaging techniques that show the structure of the brain, while an X-ray (D) is not typically used to measure brain electrical activity.
2. You design an experiment to test the effectiveness of a new fertilizer. Which of the following factors would be considered a dependent variable?
- A. The type of fertilizer used
- B. The size and age of the plants
- C. The amount of plant growth observed
- D. The cost of the fertilizer per unit
Correct answer: C
Rationale: The dependent variable is the factor that is being measured or observed in an experiment. In this case, the amount of plant growth observed is the variable that is being influenced by the independent variable, which is the type of fertilizer used. The size and age of the plants (option B) could potentially be controlled variables, while the type of fertilizer used (option A) is the independent variable being tested. The cost of the fertilizer per unit (option D) is not directly related to the plant growth being measured in this experiment.
3. Which statement best summarizes the main argument of the passage?
- A. Smart cities are a revolutionary solution to all urban challenges.
- B. Technology alone can fix modern cities' problems.
- C. Smart cities offer potential but require careful consideration of data privacy and ethical implications.
- D. Traditional city planning methods are superior to implementing smart technology.
Correct answer: C
Rationale: The passage acknowledges both the potential and concerns surrounding smart cities, making it the most accurate summary.
4. He discusses the goal of the department. Which of the following statements is a goal?
- A. Increase the patient satisfaction rate
- B. Eliminate the incidence of delayed administration of medications
- C. Establish rapport with patients.
- D. Reduce response time to two minutes.
Correct answer: A
Rationale: Option A, 'Increase the patient satisfaction rate,' is a goal because it represents an objective that the department aims to achieve. Patient satisfaction is a key indicator of quality care and reflects the department's commitment to providing excellent service. In contrast, options B, C, and D are more focused on specific actions or strategies rather than overarching goals. Eliminating delayed medication administration, establishing rapport with patients, and reducing response time are important tasks that may contribute to achieving the goal of increasing patient satisfaction, but they are not goals in themselves. Therefore, option A is the most appropriate choice as it directly addresses the department's ultimate objective of enhancing patient satisfaction.
5. Photons, the basic unit of light, are:
- A. Charged particles
- B. Packets of energy with wave-particle duality
- C. Electromagnetic waves only
- D. Always absorbed by matter
Correct answer: B
Rationale: The correct answer is B: Packets of energy with wave-particle duality. Photons are the smallest discrete amount of electromagnetic radiation and exhibit both wave-like and particle-like properties. While photons do not have a charge, they do carry energy and momentum. This dual nature of photons is a fundamental concept in quantum mechanics. Photons can travel as both waves and particles, and their behavior is described by the wave-particle duality principle. Therefore, option B accurately describes the nature of photons as packets of energy with wave-particle duality.
6. Which word best completes the sentence: "The scientist's breakthrough was met with _____ applause."
- A. thunderous
- B. scattered
- C. polite
- D. hesitant
Correct answer: A
Rationale: "Thunderous" emphasizes the intensity and volume of the applause, fitting the significance of the breakthrough.
