1. Which lobe of the brain is primarily responsible for auditory functioning?

• A. Frontal lobe
• B. Temporal lobe
• C. Occipital lobe
• D. Parietal lobe

Correct answer: B

Rationale: The correct answer is B: Temporal lobe. The temporal lobe of the brain is primarily responsible for processing auditory information, including sound perception, speech recognition, and language comprehension. Damage to the temporal lobe can lead to difficulties in hearing, understanding spoken language, and recognizing familiar sounds. Choices A, C, and D are incorrect because the frontal lobe is mainly associated with functions such as decision-making and personality, the occipital lobe is primarily responsible for processing visual information, and the parietal lobe is involved in sensory functions and spatial processing, not auditory functioning.

2. What statement from the article is correct?

• A. Chopsticks were developed in Europe.
• B. China developed chopsticks for eating utensils.
• C. Eating with forks is difficult.
• D. Space travel eliminated the need for utensils.

Correct answer: B

Rationale: The correct answer is B. The passage clearly states that China developed chopsticks as an efficient tool for eating, making choice B the correct statement. Choice A is incorrect as chopsticks were not developed in Europe but in China. Choice C is not supported by the passage as it does not discuss the difficulty of eating with forks. Choice D is also incorrect as space travel introduced new challenges but did not eliminate the need for utensils.

3. What are saturated fats saturated with?

• A. Hydrogen atoms
• B. Carbon atoms
• C. Oxygen atoms
• D. Nitrogen atoms

Correct answer: A

Rationale: Saturated fats are saturated with hydrogen atoms. This means that each carbon atom in the fatty acid chains forming saturated fats is bonded to as many hydrogen atoms as possible. This saturation results in the fatty acid chains being straight and closely packed together, making saturated fats solid at room temperature. Choice B (Carbon atoms), C (Oxygen atoms), and D (Nitrogen atoms) are incorrect because saturated fats are specifically saturated with hydrogen atoms, not carbon, oxygen, or nitrogen atoms.

4. A 60-watt lightbulb is powered by a 110-volt power source. What is the current being drawn?

• A. 0.55 amperes
• B. 1.83 amperes
• C. 50 amperes
• D. 6,600 amperes

Correct answer: A

Rationale: To calculate the current being drawn, use the formula I = P / V, where I is the current, P is the power in watts, and V is the voltage. Substituting the given values, I = 60 / 110 ≈ 0.55 amperes. Therefore, the current being drawn by the 60-watt lightbulb is approximately 0.55 amperes. Choice B, 1.83 amperes, is incorrect as it does not match the calculated value. Choices C and D, 50 amperes and 6,600 amperes, are significantly higher values and do not align with the expected current draw of a 60-watt lightbulb powered by a 110-volt source.

5. A diabetic patient's blood sugar is 180mg/dL. Their usual insulin dose is 1 unit per 40mg/dL above 100mg/dL. How much insulin should be administered?

• A. 2 units
• B. 3 units
• C. 4 units
• D. 5 units

Correct answer: B

Rationale: Rationale: 1. Calculate the excess blood sugar above 100mg/dL: 180mg/dL - 100mg/dL = 80mg/dL. 2. Determine the insulin dose based on the patient's usual insulin dose: 80mg/dL / 40mg/dL = 2 units. 3. Add the calculated insulin dose to the patient's usual insulin dose: 1 unit (usual dose) + 2 units (calculated dose) = 3 units. Therefore, the correct answer is 3 units of insulin should be administered to the diabetic patient with a blood sugar level of 180mg/dL.
