1. 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.

2. Which sentence is punctuated correctly?

• A. One of my favorite places to visit is San Francisco, California, and I'll never forget my trip there from June 2011.
• B. One of my favorite places to visit is San Francisco, California, and I'll never forget my trip there from June 2011.
• C. One of my favorite places to visit is San Francisco, California, and I'll never forget my trip there from June 2011.
• D. One of my favorite places to visit is San Francisco, California, and I'll never forget my trip there from June, 2011.

Correct answer: C

Rationale: Choice C is the correct answer. The sentence is punctuated correctly with commas separating the city, state, and the rest of the sentence. In Choice A, there should be a comma after 'California' to correctly separate the city and state. Choice B lacks a comma after 'California,' creating a run-on sentence. Choice D incorrectly uses a comma before the year '2011,' which disrupts the flow of the sentence.

3. Which part of the nervous system is responsible for transmitting signals from the sensory organs to the central nervous system?

• A. Autonomic nervous system
• B. Somatic nervous system
• C. Peripheral nervous system
• D. Central nervous system

Correct answer: C

Rationale: The correct answer is C, the peripheral nervous system. The peripheral nervous system is responsible for transmitting signals from the sensory organs to the central nervous system. It consists of nerves that connect the central nervous system to the rest of the body, including sensory nerves that carry information from the sensory organs to the brain and spinal cord. Choices A, B, and D are incorrect. The autonomic nervous system is responsible for involuntary functions like heart rate and digestion, the somatic nervous system controls voluntary movements, and the central nervous system consists of the brain and spinal cord.

4. Which of the basic elements of the writing process should be completed before the first draft is written?

• A. Prewriting
• B. Revising
• C. Conferencing
• D. Editing

Correct answer: A

Rationale: The correct answer is 'Prewriting.' Prewriting is the initial stage of the writing process where ideas are brainstormed, organized, and outlined before starting the first draft. This step involves activities such as researching, outlining, and planning the structure and content of the writing. Revising (Choice B), conferencing (Choice C), and editing (Choice D) are all important stages in the writing process, but they come after the initial prewriting phase. Revising involves making changes to the content, structure, and organization of the draft; conferencing involves getting feedback from peers or instructors; and editing focuses on correcting grammar, punctuation, and formatting errors. Therefore, prewriting is crucial as it lays the foundation for a successful writing process.

5. Which term refers to the condition where a muscle shortens in length while generating force, leading to movement at a joint?

• A. Isometric contraction
• B. Eccentric contraction
• C. Isotonic contraction
• D. Concentric contraction

Correct answer: D

Rationale: Concentric contraction refers to the condition where a muscle shortens in length while generating force, leading to movement at a joint. This type of contraction is commonly associated with the lifting phase of an exercise where the muscle is actively shortening against resistance. Isometric contraction (Choice A) involves muscle contraction without a change in muscle length, Eccentric contraction (Choice B) involves the muscle lengthening while generating force, and Isotonic contraction (Choice C) refers to muscle contraction against a constant load with a change in muscle length.
