1. A 120-volt heat lamp draws 25 amps of current. What is the lamp’s resistance?

• A. 96 ohms
• B. 104 ohms
• C. 150 ohms
• D. 4.8 ohms

Correct answer: D

Rationale: To find the resistance of the lamp, we use Ohm’s Law, which states that resistance (R) is equal to voltage (V) divided by current (I), expressed as: R = V / I. Given that the voltage (V) is 120 volts and the current (I) is 25 amps, we substitute these values into the formula: R = 120 V / 25 A = 4.8 ohms. Therefore, the resistance of the lamp is 4.8 ohms. Choice A, 96 ohms, is incorrect as it is not the result of the correct calculation. Choice B, 104 ohms, is incorrect as it does not match the calculated resistance. Choice C, 150 ohms, is incorrect as it is not the correct resistance value obtained through the calculation.

2. What is another name for aqueous HI?

• A. hydroiodic acid
• B. hydrogen monoiodide
• C. hydrogen iodide
• D. hydriodic acid

Correct answer: D

Rationale: The correct name for aqueous HI is 'hydriodic acid.' When hydrogen iodide (HI) dissolves in water, it forms hydriodic acid. Therefore, 'hydriodic acid' is the appropriate term for aqueous HI. Choice A, 'hydroiodic acid,' is incorrect as it does not reflect the nature of the compound in the aqueous state. Choice B, 'hydrogen monoiodide,' is not a widely recognized term for this compound. Choice C, 'hydrogen iodide,' is the name for HI in the gaseous state, not when it's dissolved in water.

3. Select the word or phrase that will make the sentence grammatically correct. The village is not very far _________ the railway station.

• A. to
• B. from
• C. by
• D. next

Correct answer: B

Rationale: The correct preposition to use in this sentence is 'from.' When referring to the distance between two locations, we use 'from' to indicate the starting point and 'to' to indicate the destination. In this case, the village is not very far from the railway station, showing the distance between the two places. Choice A ('to') is incorrect as it implies the village is far in the direction of the railway station. Choice C ('by') is incorrect as it suggests proximity rather than distance. Choice D ('next') is incorrect as it indicates the location of the village in relation to the railway station, not the distance between them.

4. Choose the best summary of the passage about High Fructose Corn Syrup.

• A. After extensive studies, scientists recommend removing HFCS from grocery products.
• B. A recent study on rats confirms suspicions that HFCS contributes to unhealthful weight gains.
• C. Until more research is done, using HFCS is preferable to replacing it with refined sugar.
• D. Avoiding HFCS can have immediate, healthful results on overweight patients, as suggested by the AMA.

Correct answer: B

Rationale: The best summary of the passage is choice B. The passage discusses concerns about the impact of high fructose corn syrup (HFCS) on health, particularly its link to obesity. It mentions a recent study on rats that confirms suspicions about HFCS contributing to unhealthful weight gains. Choices A, C, and D are incorrect as they introduce recommendations or implications not explicitly mentioned in the passage. Choice A goes beyond the information by stating that scientists recommend removing HFCS from grocery products, choice C suggests that using HFCS is preferable until more research is done, and choice D implies immediate healthful results on overweight patients by avoiding HFCS, as suggested by the AMA, which is not supported by the passage.

5. Choose the meaning of the word 'mercurial' in the following sentence: 'Due to his mercurial temperament, Justin did not work well with others.'

• A. Continuous
• B. Unpredictable
• C. Mercenary
• D. Miraculous

Correct answer: B

Rationale: The word 'mercurial' in this sentence means unpredictable or prone to sudden changes in mood or behavior. Justin's temperament can be characterized as unpredictable, which is causing him to not work well with others. Choice A, 'Continuous,' does not align with the meaning of 'mercurial' as it implies a steady, uninterrupted flow. Choice C, 'Mercenary,' refers to being primarily motivated by money or reward, which is not the context here. Choice D, 'Miraculous,' means extraordinary or remarkable, which is not the intended meaning in this sentence.
