1. What is the definition of power in physics?

• A. The rate of change of energy
• B. The rate of doing work or transferring energy
• C. The measure of an object's potential energy
• D. The force exerted on an object

Correct answer: B

Rationale: The correct answer is B: 'The rate of doing work or transferring energy.' Power in physics is defined as the rate at which work is done or energy is transferred. It is a measure of how quickly energy is transferred or converted. Power is not the same as energy itself but rather how fast energy is being transferred or converted. Choice A, 'The rate of change of energy,' is incorrect because power is about the rate of work or energy transfer, not just the change in energy. Choice C, 'The measure of an object's potential energy,' is incorrect as power is not a measure of potential energy but rather the rate of energy transfer. Choice D, 'The force exerted on an object,' is incorrect as power is related to work and energy transfer, not just force exerted.

2. The realtor showed __________ and __________ a house on Wednesday afternoon. Which of the following pronoun pairs should be used in the blanks above?

• A. She, I
• B. She, me
• C. Me, her
• D. Her, me

Correct answer: D

Rationale: In the sentence, 'The realtor showed her and me a house on Wednesday afternoon,' the pronouns 'her' and 'me' are used as objects of the verb 'showed.' When choosing pronouns to fill in the blanks, it is important to use objective pronouns to maintain correct grammar and sentence structure. Choice A ('She, I') and Choice B ('She, me') are incorrect as 'I' and 'she' are subjective pronouns, not objective pronouns needed as objects in this sentence. Choice C ('Me, her') is also incorrect as the order and usage of pronouns are reversed from the correct form in the sentence.

3. Choose the sentence that most effectively follows the conventions of standard written English:

• A. Wilbur and Orville Wright were two brothers who tested their prototype airplane on a beach in Kitty Hawk, North Carolina.
• B. The two brothers, Wilbur and Orville Wright, tested their prototype airplane on a beach in Kitty Hawk, North Carolina.
• C. The two brothers, Wilbur and Orville Wright, were testing their prototype airplane on a beach in Kitty Hawk, North Carolina.
• D. The beach in Kitty Hawk, North Carolina was where the two brothers, Wilbur and Orville Wright, came to test their prototype airplane.

Correct answer: B

Rationale: The correct answer is B. This sentence effectively follows the conventions of standard written English by clearly presenting the subject ('The two brothers, Wilbur and Orville Wright') and the verb ('tested') with appropriate punctuation. Choice A introduces an unnecessary comma and could be more concise. Choice C changes the tense of the verb to 'were testing,' which is not required for the context provided. Choice D creates a more awkward sentence structure by placing the location at the beginning and using 'came and tested,' which is less direct than 'tested'. Thus, Choice B is the most effective and grammatically correct option.

4. Select the pronoun that could be used in the following sentence: Mrs. Sato, _______ lives down the street, is 99 years old.

• A. she
• B. who
• C. which
• D. whom

Correct answer: B

Rationale: The correct answer is 'B' - 'who.' 'Who' is the correct relative pronoun to introduce the clause 'who lives down the street,' providing more information about Mrs. Sato. The other choices, 'she,' 'which,' and 'whom,' are not appropriate relative pronouns for referring to a person in this context.

5. A patient requires a 30% decrease in their medication dosage. Their current dosage is 340 mg. What will their dosage be after the decrease?

• A. 70 mg
• B. 238 mg
• C. 270 mg
• D. 340 mg

Correct answer: B

Rationale: To calculate a 30% decrease of 340 mg, multiply 340 by 0.30 to get 102. Subtracting 102 from 340 gives a new dosage of 238 mg. Choice A (70 mg) is incorrect as it represents a 80% decrease, not 30%. Choice C (270 mg) is incorrect as it does not reflect a decrease but rather the original dosage. Choice D (340 mg) is incorrect as it is the original dosage and not reduced by 30%.
