1. Temperature Conversion & Interpretation: A patient's body temperature is 102°F. Convert this to °C and assess if it indicates a fever.

• A. 37°C (Normal)
• B. 39°C (Low-grade fever)
• C. 39°C (Fever)
• D. 42°C (Hyperthermia)

Correct answer: C

Rationale: Rationale: 1. To convert Fahrenheit to Celsius, you can use the formula: °C = (°F - 32) x 5/9. 2. Given that the patient's body temperature is 102°F, we can calculate the equivalent temperature in Celsius: °C = (102 - 32) x 5/9 °C = 70 x 5/9 °C = 350/9 °C ≈ 38.9°C, which can be rounded to 39°C. 3. A body temperature of 39°C is considered to indicate a fever. Normal body temperature typically ranges from 36.1°C to 37.2°C, so a temperature of 39°C is higher than the normal range and suggests a fever. 4. Options A and B are incorrect as they do not reflect the conversion of 102°F to °C

2. The energy required to break a chemical bond is called:

• A. Kinetic energy
• B. Potential energy
• C. Activation energy
• D. Bond energy

Correct answer: C

Rationale: Rationale: Activation energy is the energy required to break a chemical bond and initiate a chemical reaction. Kinetic energy (option A) is the energy of motion, potential energy (option B) is stored energy, and bond energy (option D) is the energy required to break a particular chemical bond in a molecule. Among the options provided, activation energy best describes the energy required to break a chemical bond.

3. The urethra is the tube that carries urine from the bladder to the outside of the body. How does urine flow through the urethra?

• A. Continuously
• B. Only when the bladder is completely full
• C. Under voluntary control of sphincter muscles
• D. A combination of b) and c)

Correct answer: C

Rationale: The correct answer is C: "Under voluntary control of sphincter muscles." The urethra is the tube responsible for carrying urine from the bladder to the outside of the body. Urine flow through the urethra is not continuous but rather under voluntary control. The sphincter muscles, located at the opening of the bladder and urethra, help control the release of urine. This control allows individuals to regulate when and where they empty their bladder, providing a mechanism to prevent involuntary leakage of urine. Therefore, option C accurately describes how urine flows through the urethra.

4. What is the condition called when someone experiences a temporary loss of consciousness due to a lack of blood flow to the brain?

• A. Stroke
• B. Epilepsy
• C. Syncope (fainting)
• D. Multiple sclerosis

Correct answer: C

Rationale: The correct answer is C: 'Syncope (fainting)'. Syncope is the temporary loss of consciousness caused by a temporary drop in blood flow to the brain, leading to a lack of oxygen reaching the brain. This can occur due to various reasons such as dehydration, sudden drop in blood pressure, or emotional stress. A stroke (option A) is a sudden interruption in the blood supply to the brain, leading to brain cell damage. Epilepsy (option B) is a neurological disorder characterized by recurrent seizures. Multiple sclerosis (option D) is a chronic autoimmune disease that affects the central nervous system. Therefore, the correct term for a temporary loss of consciousness due to lack of blood flow to the brain is syncope.

5. The author's tone towards UBI can be described as

• A. Strongly supportive, advocating for its immediate implementation without reservations.
• B. Strongly critical, highlighting only the potential drawbacks and dismissing its benefits.
• C. Neutral and objective, presenting both sides of the argument without taking a stance.
• D. Cautiously optimistic, acknowledging both the potential and challenges while calling for further discussion.

Correct answer: D

Rationale: The passage acknowledges both positive and negative aspects of UBI, suggesting a cautious and balanced perspective, aligning with D.

6. Positive integers are greater than zero. Which of the following expressions results in the largest positive number?

• A. (2 + 3)^2
• B. 5 x 7 + 2
• C. 10^2 - 4^2
• D. (8 - 1) x 3

Correct answer: C

Rationale: 10^2 - 4^2 = 100 - 16 = 84
