1. Which of the following represents the correct plural form of the word 'syllabus'?
- A. Syllabus
- B. Syllaba
- C. Syllabi
- D. Syllabis
Correct answer: C
Rationale: The correct plural form of 'syllabus' is 'syllabi.' In English, when a word ends in -us, the plural form is often changed to -i. Therefore, 'Syllabi' is the correct plural form. Choice A, 'Syllabus,' is the singular form, not the plural. Choice B, 'Syllaba,' does not follow the standard pluralization rule for words ending in -us. Choice D, 'Syllabis,' is an incorrect plural form that does not follow the standard English pluralization rules.
2. What is the longest bone in the human body?
- A. Tibia
- B. Fibula
- C. Femur
- D. Humerus
Correct answer: C
Rationale: The femur is indeed the longest bone in the human body. It extends from the hip to the knee, providing crucial support for the body's weight and enabling various movements. The tibia and fibula are bones in the lower leg, while the humerus is located in the upper arm. Therefore, choices A, B, and D are incorrect in this context.
3. When making a dilution, what do you do?
- A. Add more solvent to a concentrated solution
- B. Change the temperature of the solution
- C. Decrease the concentration of a solution
- D. All of the above
Correct answer: C
Rationale: When making a dilution, you decrease the concentration of a solution by adding more solvent to a concentrated solution. This process does not involve changing the temperature of the solution, so option B is incorrect. Option A is also incorrect because you are not adding more solute to the solution during dilution. Therefore, the correct answer is C) Decrease the concentration of a solution. Options A and B are incorrect as dilution involves adding more solvent, not solute, and does not require changing the temperature of the solution.
4. What is the average length of a human eyelash?
- A. 1 nanometer
- B. 1 centimeter
- C. 1 meter
- D. 1 kilometer
Correct answer: B
Rationale: The average length of a human eyelash is approximately one centimeter. A nanometer is too small to describe the length of an eyelash. A meter and a kilometer are much longer lengths and not suitable to describe the average human eyelash.
5. What is the main function of the epiglottis, a small flap of cartilage located above the larynx?
- A. To warm and humidify inhaled air
- B. To control the passage of food and air
- C. To produce sound vibrations for speech
- D. To sense the presence of foreign objects
Correct answer: B
Rationale: The main function of the epiglottis is to control the passage of food and air. It acts as a cover for the trachea during swallowing to prevent food from entering the airway. This mechanism ensures that food safely travels down the esophagus to the stomach, while air simultaneously enters the trachea and moves into the lungs for respiration. Choice A is incorrect as the warming and humidifying of inhaled air primarily occur in the nasal cavity. Choice C is incorrect because sound production for speech involves structures like the vocal cords rather than the epiglottis. Choice D is incorrect as sensing foreign objects is not a primary function of the epiglottis; instead, this role is typically associated with sensory receptors in the respiratory tract.
