1. What is it called when base units are combined, such as g/mL for density?

• A. combined units
• B. derived units
• C. base units
• D. calculated units

Correct answer: B

Rationale: The correct answer is B: derived units. When base units (such as grams or milliliters) are combined, as seen in g/mL (grams per milliliter) for density, they form derived units. Derived units measure complex quantities that are derived from combinations of base units. Choice A, 'combined units,' is incorrect as it does not specifically refer to the formation of new units from base units. Choice C, 'base units,' is incorrect because base units are the fundamental units from which all other units are derived, not the combinations of units. Choice D, 'calculated units,' is incorrect as it does not accurately describe the concept of combining base units to form a new unit like g/mL for density.

2. What is the meaning of the idiom 'to bite off more than one can chew'?

• A. To be overly confident
• B. To take on more than one can handle
• C. To be easily discouraged
• D. To be meticulous in planning

Correct answer: B

Rationale: The correct answer is B: 'To bite off more than one can chew' means to take on more than one can handle or to undertake a task exceeding one's capabilities. This idiom warns against overcommitting oneself and facing difficulties in managing the workload effectively. Choice A, 'To be overly confident,' is incorrect as the idiom implies a situation of overestimating one's capacity rather than confidence. Choice C, 'To be easily discouraged,' is not related to the idiom's meaning, which focuses on task difficulty rather than emotional response. Choice D, 'To be meticulous in planning,' is not accurate as the idiom refers to the execution of tasks rather than the planning phase.

3. Which word is most closely synonymous with the word patronage as it appears in the following statement?

• A. Auspices
• B. Aberration
• C. Adulation
• D. Applause

Correct answer: A

Rationale: 'Auspices' is most synonymous with 'patronage' in this context, indicating support or sponsorship. In the provided extract, the author expresses a desire to meet with the working men and their families, indicating a sense of support and sponsorship towards them, aligning with the meaning of 'auspices.' The other choices do not capture the idea of support or sponsorship and are therefore incorrect.

4. During January, Dr. Lewis worked 20 shifts. During February, she worked three times as many shifts as she did during January. During March, she worked half the number of shifts she worked during February. Which equation below describes the number of shifts Dr. Lewis worked in March?

• A. shifts = 20 + 3 + 1/2
• B. shifts = (20)(3)(1/2)
• C. shifts = (20)(3) + 1/2
• D. shifts = 20 + (3)(1/2)

Correct answer: B

Rationale: During January, Dr. Lewis worked 20 shifts. Shifts for January = 20. During February, she worked three times as many shifts as she did during January. Shifts for February = (20)(3) = 60. During March, she worked half the number of shifts she worked in February. Shifts for March = (60)(1/2) = 30. Therefore, the correct equation to describe the number of shifts Dr. Lewis worked in March is 'shifts = (20)(3)(1/2)', representing the calculation based on the given scenario. Choices A, C, and D do not accurately represent the correct mathematical relationship between the shifts worked in the different months, making them incorrect.

5. What force causes an object to move in a circular path?

• A. Tension force
• B. Frictional force
• C. Centripetal force
• D. Gravitational force

Correct answer: C

Rationale: The centripetal force is the force responsible for keeping an object moving in a circular path. It is directed towards the center of the circle, providing the necessary inward acceleration to maintain the object's curved trajectory. Without this force, the object would move in a straight line tangent to the circle. Tension force, frictional force, and gravitational force are not the forces that cause an object to move in a circular path. Tension force is typically present in a string or rope and acts along the length of the material. Frictional force opposes the motion of an object relative to a surface, and gravitational force is the force of attraction between two masses.
