1. Which part of the respiratory system is in the upper respiratory tract?

• A. Bronchioles
• B. Alveolar ducts
• C. Alveoli
• D. None of the above

Correct answer: D

Rationale: The upper respiratory tract includes structures such as the nose, nasal cavity, pharynx, and larynx. These structures are responsible for filtering, warming, and humidifying the air. The lower respiratory tract comprises the trachea, bronchi, bronchioles, alveolar ducts, and alveoli. Bronchioles, alveolar ducts, and alveoli are all part of the lower respiratory system, involved in gas exchange. Therefore, the correct answer is 'None of the above' as none of the listed options are part of the upper respiratory tract.

2. Which numeric system does not use place value?

• A. Roman
• B. Arabic
• C. Decimal
• D. Binary

Correct answer: A

Rationale: The Roman numeric system does not use place value as the Arabic, Decimal, and Binary systems do. In the Roman numeral system, the value of each symbol is independent of its position, unlike in the other systems where the position of a digit affects its value. This unique characteristic of Roman numerals distinguishes them from place-value systems like Arabic, Decimal, and Binary. Therefore, the correct answer is Roman (Choice A). Choices B, C, and D (Arabic, Decimal, and Binary) all utilize place value, where the position of a digit within a number determines its value, unlike Roman numerals.

3. The information presented is:

• A. Slanted in favor of newscasters
• B. Slanted against people with deep voices
• C. Balanced in its approach
• D. Not applicable

Correct answer: C

Rationale: The information is balanced in its approach. While the extract mentions that women tend to have shriller voices, making them less desirable public speakers, newscasters, or political candidates, it does not show bias in favor of newscasters or against people with deep voices. The main focus is on the impact of voice qualities such as harshness, rather than promoting or criticizing any specific group.

4. A bicycle and a car are both traveling at a rate of 5 m/s. Which statement is true?

• A. The bicycle has more kinetic energy than the car.
• B. The bicycle has less kinetic energy than the car.
• C. Both vehicles have the same amount of kinetic energy.
• D. Only the car has kinetic energy.

Correct answer: B

Rationale: Kinetic energy is determined by both the mass and the velocity of an object. While both the bicycle and the car are moving at the same velocity (5 m/s), the car has significantly more mass than the bicycle. As a result, the car has more kinetic energy than the bicycle, even though their speeds are identical. Therefore, choice B is correct. Choices A, C, and D are incorrect because they do not consider the influence of mass on kinetic energy. Choice A is incorrect as the car has more kinetic energy due to its greater mass. Choice C is incorrect because the vehicles have different masses. Choice D is incorrect as both the bicycle and the car possess kinetic energy.

5. What does 'insidious' mean?

• A. Immediate and obvious
• B. So gradual as to not become apparent for a long time
• C. Sudden and severe
• D. Quick and detectable

Correct answer: B

Rationale: The correct definition of 'insidious' is 'So gradual as to not become apparent for a long time.' This term describes something that develops slowly and may not be noticed initially. Choice A, 'Immediate and obvious,' is incorrect because 'insidious' implies the opposite of being immediate. Choice C, 'Sudden and severe,' is incorrect because 'insidious' suggests a slow and subtle progression, not sudden. Choice D, 'Quick and detectable,' is incorrect because 'insidious' does not indicate something quick or easily detectable.
