English Grammar

1. Which sentence uses the word "literally" correctly?

Correct answer: B

Rationale: Option B uses "literally" to emphasize the magnitude of work, not to exaggerate a simple action.

2. Which respiratory structure is responsible for the production of mucus to trap particles and for the movement of cilia to sweep mucus and trapped particles out of the respiratory tract?

Correct answer: D

Rationale: The correct answer is D: Respiratory epithelium. The respiratory epithelium is a specialized tissue lining the respiratory tract that produces mucus to trap particles and contains cilia that beat in a coordinated manner to move the mucus and trapped particles out of the respiratory tract. The trachea, larynx, and bronchi are all structures within the respiratory system, but they do not directly produce mucus or have cilia for sweeping particles. Therefore, the respiratory epithelium is the specific structure responsible for these functions.

3. A lab test result shows a blood glucose level of 5.5 millimoles per liter (mmol/L). What is the equivalent level in milligrams per deciliter (mg/dL)?

Correct answer: A

Rationale: This requires a double conversion: millimoles to milligrams and liters to deciliters. 1 millimole is equal to 180.15 milligrams, and 1 liter is equal to 10 deciliters. Multiply the glucose level (5.5 mmol/L) by the conversion factor for millimoles to milligrams (180.15 mg/mmol) and then divide by the conversion factor for liters to deciliters (10 dL/L): 5.5 mmol/L * 180.15 mg/mmol / 10 dL/L ≈ 55 mg/dL.

4. In the sentence "The house was dilapidated," what effect does the word "dilapidated" have on the reader's understanding?

Correct answer: C

Rationale: The word "dilapidated" specifically describes the house's deteriorating state.

5. Which part of the brainstem is responsible for controlling vital functions such as heart rate, blood pressure, and breathing?

Correct answer: a

Rationale: The correct answer is A: Medulla oblongata. The medulla oblongata is the lower part of the brainstem that regulates vital autonomic functions such as heart rate, blood pressure, and breathing. It contains important centers for controlling these essential bodily functions, making it a critical part of the brain for maintaining life. The pons, midbrain, and cerebellum are also parts of the brainstem, but they are not primarily responsible for regulating these vital functions. Therefore, the medulla oblongata is the specific region of the brainstem that directly controls these essential physiological processes.

6. Which blood vessels carry oxygenated blood from the heart to the rest of the body?

Correct answer: C

Rationale: The correct answer is C: Systemic arteries. Systemic arteries carry oxygenated blood from the heart to the rest of the body, delivering vital nutrients and oxygen to tissues and organs. Pulmonary arteries carry deoxygenated blood from the heart to the lungs for oxygenation. Pulmonary veins carry oxygenated blood from the lungs back to the heart. Systemic veins return deoxygenated blood from the body to the heart. It's important to differentiate between pulmonary and systemic vessels in understanding the circulation of blood throughout the body.
