1. Select the correct word for the blank in the following sentence: The intern and ___________ are folding the bandages.

• A. us
• B. he
• C. them
• D. her

Correct answer: C

Rationale: In this sentence, the correct word to use is 'them.' The subject of the sentence is 'the intern and another person,' indicating more than one individual. Therefore, the pronoun 'them' is the appropriate choice to refer to multiple people engaged in folding the bandages. Choice A ('us') is incorrect as it refers to the speaker and the intern, not the intern and another person. Choice B ('he') is singular and does not match the plural subject of the sentence. Choice D ('her') is also singular and does not agree with the plural subject 'the intern and another person.'

2. What does 'External' refer to?

• A. Inside the body
• B. Located outside the body
• C. Exposed internally
• D. Near the skin

Correct answer: B

Rationale: The term 'External' refers to something that is located outside the body. In this context, it specifically denotes a position or location that is beyond the confines of the body's boundaries. Choice A is incorrect as 'External' means outside, not inside. Choice C is incorrect as it confuses the internal exposure with external positioning. Choice D is incorrect as 'External' does not necessarily mean near the skin, but rather outside the body.

3. How many gallons are in 576 fluid ounces?

• A. 4 gallons
• B. 5 gallons
• C. 6 gallons
• D. 3 gallons

Correct answer: A

Rationale: To convert fluid ounces to gallons, you need to know that there are 128 fluid ounces in a gallon. To find how many gallons are in 576 fluid ounces, divide 576 by 128, which equals 4.5 gallons. Since we are looking for the closest whole number, the answer is 4 gallons. Choice A is correct. Choice B, C, and D are incorrect as they do not accurately represent the conversion from fluid ounces to gallons.

4. In physics, the relationship between acceleration and force is expressed in ___________.

• A. Newton’s first law of motion
• B. Newton’s second law of motion
• C. Newton’s third law of motion
• D. none of Newton’s laws of motion

Correct answer: B

Rationale: The relationship between acceleration and force is expressed in Newton’s second law of motion. This law states that the acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to the object's mass. Mathematically, this relationship is represented as F = ma, where F is the force, m is the mass of the object, and a is the acceleration. Choice A, Newton’s first law of motion, also known as the law of inertia, states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an external force. Choice C, Newton’s third law of motion, states that for every action, there is an equal and opposite reaction, focusing on the interaction between two objects. Choice D is incorrect because the relationship between acceleration and force is indeed described by one of Newton’s laws of motion, specifically the second law.

5. What is the function of the kidneys in the urinary system?

• A. To filter blood and remove waste
• B. To produce red blood cells
• C. To regulate blood pressure
• D. To absorb water

Correct answer: A

Rationale: The correct answer is A: 'To filter blood and remove waste.' The kidneys play a crucial role in the urinary system by filtering blood to remove waste products and excess fluids, which are then excreted as urine. This process helps maintain the body's internal balance by regulating electrolyte levels and controlling blood pressure. Choices B, C, and D are incorrect because the kidneys do not produce red blood cells (bone marrow does), regulate blood pressure directly (although they indirectly influence it through the renin-angiotensin-aldosterone system), or absorb water (they regulate water balance but do not absorb water).
