1. How many milliliters are in 3 liters?

Correct answer: B

Rationale: The correct answer is B: 3000 milliliters. There are 1,000 milliliters in a liter. Therefore, 3 liters = 3 × 1,000 = 3,000 milliliters. Choice A (300 milliliters) is incorrect as it represents the conversion of 0.3 liters, not 3 liters. Choice C (1500 milliliters) is incorrect as it is halfway between the correct answer and a common mistake of confusing liters with milliliters. Choice D (300 milliliters) is incorrect as it is the conversion of 0.3 liters, not 3 liters.

2. Which phrase best completes the sentence: 'Despite _____, he managed to complete the race.'

Correct answer: A

Rationale: The correct answer is 'A: his injury.' In the context of completing a race, an injury would be a significant obstacle to overcome. While choices B, C, and D could also pose challenges, an injury is the most severe hindrance that would make completing a race particularly difficult. His condition, pain, or fatigue may affect performance, but they are not as directly impactful as an injury in this scenario.

3. Another word for STRICT is?

Correct answer: A

Rationale: The correct answer is A, "Stringent." The term "stringent" is a synonym for "strict," both denoting being rigid, precise, or exacting in rules, requirements, or standards. Choices B, C, and D are incorrect as they do not carry the same meaning as "strict." 'Daily' and 'weekly' refer to frequency, while 'nominal' means minimal or insignificant, which are not synonymous with strict.

4. He has 3 DISCRETE symptoms, causing the doctor to create an elaborative plan of care.

Correct answer: D

Rationale: The term 'discrete' means individually separate and distinct. Therefore, the most appropriate choice to describe the symptoms that are distinct and separate from each other is 'separate' (option D). Choices A, B, and C are incorrect because they do not convey the specific meaning of the term 'discrete' as separate and distinct.

5. Which of the following substances has the highest density?

Correct answer: B

Rationale: Water has the highest density among the options provided. Density is a measure of mass per unit volume. In this case, water in its liquid form is denser than mist, steam, and ice. Ice has a lower density than water because its crystalline structure causes it to be less dense. Mist and steam are forms of water vapor, which are much less dense than liquid water. Therefore, the correct answer is water (choice B).
