1. Select the word or phrase that makes this sentence grammatically correct: 'The development committee ____ a bargain with the city planners.'

• A. striked
• B. stroke
• C. struck
• D. strike

Correct answer: C

Rationale: The correct answer is 'C: struck.' In this context, the correct verb form should be 'struck' as it is the past tense form of 'strike.' Therefore, the correct sentence should read: 'The development committee struck a bargain with the city planners.' Choice A, 'striked,' is incorrect as 'strike' is an irregular verb, and the past tense is 'struck' rather than 'striked.' Choice B, 'stroke,' is incorrect as it is not the correct past tense form of 'strike' in this context. Choice D, 'strike,' is incorrect as it is the base form of the verb and does not fit the sentence structure requiring a past tense verb.

2. What characterizes laminar flow?

• A. Smooth, parallel layers of fluid particles
• B. Erratic and turbulent motion of fluid particles
• C. High viscosity hindering flow
• D. Incompressibility of the fluid

Correct answer: A

Rationale: Laminar flow is characterized by the smooth, parallel movement of fluid particles along layers in a predictable manner. This flow regime occurs at low velocities and is in contrast to turbulent flow, where fluid particles exhibit erratic and chaotic motion. The viscosity of the fluid does not hinder laminar flow; instead, it influences the resistance to flow. Incompressibility is a property of fluids but does not specifically define laminar flow. Therefore, the correct answer is A as it accurately describes the behavior of fluid particles in laminar flow, making B, C, and D incorrect.

3. Solve for x: x/250 = 3/500.

• A. 150
• B. 25.5
• C. 1.5
• D. 60

Correct answer: C

Rationale: To solve for x, cross-multiply: x/250 = 3/500. This simplifies to x = 1.5. Therefore, the correct answer is 1.5. Choice A (150) is incorrect because it does not account for the division by 250. Choice B (25.5) is incorrect as it is not the correct result of the calculation. Choice D (60) is incorrect as it is not the correct result of the calculation either.

4. Which structure is responsible for carrying oxygen to the cells?

• A. Hemoglobin
• B. Plasma
• C. Platelets
• D. Red blood cells

Correct answer: A

Rationale: Hemoglobin, located in red blood cells, is responsible for binding to oxygen in the lungs and transporting it to tissues throughout the body. Red blood cells contain hemoglobin, making them the primary carrier of oxygen to cells. Hemoglobin is the correct answer because it is the protein within red blood cells that directly binds to oxygen for transport. Plasma is the liquid component of blood and does not carry oxygen. Platelets are responsible for blood clotting and have no role in oxygen transport. While red blood cells do carry oxygen, it is specifically the hemoglobin within them that performs this function.

5. Which of the following words or phrases fits best in the following sentence? The radiology department sends Troy to pick up lunch ______ it isn’t too busy at the office.

• A. as long as
• B. as if
• C. after
• D. unless

Correct answer: A

Rationale: The phrase 'as long as' is used to indicate a condition that needs to be met for the main clause to happen. In this sentence, the radiology department sends Troy to pick up lunch only if it isn't too busy at the office, so 'as long as' is the most suitable phrase to convey this conditional relationship. Choice B, 'as if,' implies a hypothetical comparison rather than a condition. Choice C, 'after,' suggests a sequence of events rather than a condition. Choice D, 'unless,' introduces a negative condition which does not fit the context of the sentence.
