1. Identify the independent clause in the following sentence: 'While the chef prepared dinner, the guests chatted and enjoyed the music.'

• A. While the chef prepared dinner
• B. the guests chatted and enjoyed the music
• C. While the chef prepared dinner
• D. the guests chatted and enjoyed

Correct answer: B

Rationale: The correct answer is 'B' - 'the guests chatted and enjoyed the music.' An independent clause expresses a complete thought and can stand alone as a sentence. It typically includes a subject and a verb and does not rely on another clause to form a complete sentence. In this sentence, 'the guests chatted and enjoyed the music' fits this criteria, making it the independent clause. Choices A and C are incorrect as they are dependent clauses, starting with a subordinating conjunction 'While,' which shows they cannot stand alone as complete sentences. Choice D is also incorrect as it lacks the word 'the' before 'enjoyed,' making it grammatically incomplete.

2. What is 0.875 as a fraction?

• A. 7/8
• B. 9/10
• C. 5/6
• D. 3/4

Correct answer: A

Rationale: To convert 0.875 to a fraction, you can write it as 875/1000. Simplifying this fraction by dividing the numerator and denominator by their greatest common divisor, which is 125, gives you 7/8. Therefore, the correct answer is 7/8. Choice B (9/10), Choice C (5/6), and Choice D (3/4) are incorrect as they do not represent the fraction equivalent of 0.875.

3. What is the normal (complete) flow of blood through the heart?

• A. Right atrium → lungs → left atrium → body
• B. Left atrium → left ventricle → body → right atrium
• C. Right atrium → right ventricle → lungs → left atrium → left ventricle → aorta → body
• D. Right ventricle → left ventricle → body

Correct answer: C

Rationale: The correct flow of blood through the heart starts with the right atrium receiving deoxygenated blood from the body, followed by the right ventricle pumping blood to the lungs for oxygenation. Oxygenated blood then returns to the heart through the left atrium, then passes to the left ventricle which pumps it out to the body through the aorta. This flow ensures that blood is properly oxygenated before circulating through the body. Choice A is incorrect as the blood does not go directly from the left atrium to the body, skipping the left ventricle. Choice B is incorrect as it does not follow the correct flow sequence in the heart. Choice D is incorrect as it does not include the full pathway of blood through the heart.

4. What is 0.04 grams converted to milligrams?

• A. 40 mg
• B. 4 mg
• C. 400 mg
• D. 0.4 mg

Correct answer: A

Rationale: To convert grams to milligrams, you need to multiply by 1000, not 10000. Therefore, to convert 0.04 grams to milligrams, you multiply 0.04 by 1000, which equals 40 mg. Choice A (40 mg) is the correct answer. Choice B (4 mg) is incorrect as it represents converting 0.004 grams to milligrams. Choice C (400 mg) is incorrect as it is 10 times the correct conversion. Choice D (0.4 mg) is incorrect as it is 10 times smaller than the correct conversion.

5. What is it called when base units are combined, such as g/mL for density?

• A. combined units
• B. derived units
• C. base units
• D. calculated units

Correct answer: B

Rationale: The correct answer is B: derived units. When base units (such as grams or milliliters) are combined, as seen in g/mL (grams per milliliter) for density, they form derived units. Derived units measure complex quantities that are derived from combinations of base units. Choice A, 'combined units,' is incorrect as it does not specifically refer to the formation of new units from base units. Choice C, 'base units,' is incorrect because base units are the fundamental units from which all other units are derived, not the combinations of units. Choice D, 'calculated units,' is incorrect as it does not accurately describe the concept of combining base units to form a new unit like g/mL for density.
