1. Which term best describes a synthetic drug?

• A. man-made
• B. phony
• C. atypical
• D. futile

Correct answer: A

Rationale: A synthetic drug is one that is artificially created in a laboratory setting rather than occurring naturally. The term 'man-made' accurately describes this process. Choices B, C, and D are incorrect. 'Phony' means fake or fraudulent, not specifically related to synthetic drugs. 'Atypical' means unusual or not typical, which doesn't directly relate to how synthetic drugs are made. 'Futile' means pointless or ineffective, which is not a characteristic of synthetic drugs.

2. For his daily commute, Paul drives about 115 miles round trip. If he fills up his gas tank with 9 gallons every other day, about how many miles per gallon is his car averaging?

• A. 12.8
• B. 23
• C. 25.6
• D. 57.5

Correct answer: C

Rationale: To find the miles per gallon Paul's car is averaging, we first need to determine the miles he drives on 9 gallons of gas. Since he drives about 115 miles round trip daily, he covers approximately 115/2 = 57.5 miles one way. If he fills up his gas tank with 9 gallons every other day, he covers 115 miles every 2 days. This means his car is averaging around 57.5 miles per 9 gallons, which equals approximately 6.38 miles per gallon. As he uses 9 gallons every other day, his car averages about 6.38 * 2 = 12.76 miles per gallon. Among the given options, the closest value to this calculation is option C, 25.6 miles per gallon. Choice A is incorrect because it does not accurately reflect the mileage per gallon calculation. Choice B is incorrect as it is not the closest to the calculated value. Choice D is incorrect as it is significantly higher than the calculated mileage per gallon.

3. A patient's oxygen flow rate is set at 4 liters per minute. How many cubic centimeters of oxygen are delivered per minute?

• A. 400 cubic centimeters
• B. 4,000 cubic centimeters
• C. 40,000 cubic centimeters
• D. 400,000 cubic centimeters

Correct answer: B

Rationale: 1 liter is equal to 1,000 cubic centimeters. Therefore, when the oxygen flow rate is 4 liters per minute, the calculation is 4 x 1,000 = 4,000 cubic centimeters. Hence, at a flow rate of 4 liters per minute, 4,000 cubic centimeters of oxygen are delivered per minute. Choice A, 400 cubic centimeters, is incorrect because it miscalculates the conversion from liters to cubic centimeters. Choices C and D, 40,000 cubic centimeters and 400,000 cubic centimeters, respectively, are significantly higher than the correct answer due to incorrect conversions or additional errors in calculation.

4. In the passage the word embark means to:

• A. Remove the covering from a tree
• B. Speak harshly to others
• C. Entertain the reader
• D. Put or go on board a ship

Correct answer: D

Rationale: The word 'embark' typically means to board a ship or begin a journey. In this context, it means to start or set out on a new undertaking or venture, often including the act of boarding a ship. In the provided passage about the Golden Gate Bridge, it is mentioned that builders, architects, and workers embarked on the challenge of building a bridge across the Golden Gate Strait, which refers to them starting this new undertaking. Therefore, the correct definition of 'embark' is D. Put or go on board a ship. The other choices are incorrect: A. Removing the covering from a tree is unrelated to the context of the passage. B. Speaking harshly to others and C. Entertaining the reader are also irrelevant to the meaning of 'embark' in this context.

5. What is the correct formula for iron III oxide?

• A. IO
• B. FeS
• C. Fe₂O₃
• D. OFe₂₃

Correct answer: C

Rationale: The correct formula for iron III oxide is Fe2O3. In this formula, Fe represents iron and O represents oxygen. Iron III oxide consists of two iron (Fe) ions combined with three oxygen (O) ions. Thus, the correct formula is Fe2O3. Choice A (IO) is incorrect as it does not represent the correct combination of iron and oxygen ions. Choice B (FeS) is incorrect as it represents iron sulfide, not iron III oxide. Choice D (OFe₂₃) is incorrect as it does not follow the correct chemical nomenclature for iron III oxide.
