1. In a circuit with three same-size resistors wired in series to a 9-V power supply, producing 1 amp of current, what is the resistance of each resistor?

• A. 9 ohms
• B. 6 ohms
• C. 3 ohms
• D. 1 ohm

Correct answer: C

Rationale: In a series circuit, the total resistance is the sum of the individual resistances. With a total voltage of 9 V and a current of 1 A, we can use Ohm's Law (V = I × R) to find the total resistance: Total resistance = 9 V / 1 A = 9 ohms. Since the resistors are identical and wired in series, the total resistance is evenly divided among the three resistors: Resistance of each resistor = 9 ohms / 3 = 3 ohms. Thus, the resistance of each resistor is 3 ohms. Therefore, the correct answer is 3 ohms. Choice A, 9 ohms, is incorrect because this would be the total resistance of all three resistors combined in series. Choice B, 6 ohms, is incorrect as it does not account for the equal distribution of resistance in a series circuit. Choice D, 1 ohm, is incorrect as it is too low for resistors in series with a total resistance of 9 ohms.

2. Which word is not spelled correctly in the context of the following sentence? Nothing can be more delightful than a late-night swim in the reservoir.

• A. Nothing
• B. delightful
• C. then
• D. reservoir

Correct answer: C

Rationale: In the context of the sentence, the word 'then' is used incorrectly. The correct word that should be used is 'than,' which is used to make comparisons. The sentence should read, 'Nothing can be more delightful than a late-night swim in the reservoir.' The other choices 'Nothing,' 'delightful,' and 'reservoir' are spelled correctly and are contextually appropriate in the sentence.

3. Select the word or phrase that makes the following sentence grammatically correct: 'Screaming ____ took the shopkeeper by surprise.'

• A. We
• B. They
• C. Them
• D. Our

Correct answer: D

Rationale: The correct answer is 'Our.' In this sentence, the possessive pronoun 'Our' is needed to show ownership and make the sentence grammatically correct. 'Screaming our took the shopkeeper by surprise' indicates that the shopkeeper was surprised by the screaming of a group or individuals related to 'our.' Choices A, B, and C are incorrect as they are pronouns referring to people ('We', 'They', 'Them'), not possessive pronouns that indicate ownership.

4. Select the correct word for the blank in the following sentence: Nurse Junko and ________ will review the patient’s chart.

• A. me
• B. she
• C. them
• D. him

Correct answer: B

Rationale: In this sentence, the correct word to use after 'and' is a pronoun that would refer to Nurse Junko as another person. Since 'Nurse Junko' is a singular female subject, the appropriate pronoun to use is 'she.' Therefore, the correct choice is 'she.' Choice 'A' ('me') is incorrect because it is an object pronoun, not a subject pronoun. Choice 'C' ('them') is incorrect because it is a plural pronoun and does not agree with the singular subject 'Nurse Junko.' Choice 'D' ('him') is incorrect because it is a masculine pronoun, while the subject 'Nurse Junko' is a singular female, so the pronoun should be feminine.

5. Multiply 4/9 x 1 & 4/5 x 2/5.

• A. 15
• B. 7/16
• C. 8/25
• D. 19

Correct answer: C

Rationale: To multiply fractions, you multiply the numerators together and the denominators together. Calculating 4/9 x 1 & 4/5 x 2/5 gives you (4 x 1) / (9 x 1) & (4 x 2) / (5 x 5) = 4/9 & 8/25. Therefore, the correct answer is 8/25. Choices A, B, and D are incorrect because they do not result from the correct multiplication of the fractions provided.
