1. What is the relationship between force and acceleration according to Newton's second law?

• A. Force is directly proportional to acceleration
• B. Force is inversely proportional to acceleration
• C. Force has no relation to acceleration
• D. Force causes deceleration, not acceleration

Correct answer: A

Rationale: According to Newton's second law of motion, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This relationship is mathematically expressed as F = ma, where F represents force, m represents mass, and a represents acceleration. Therefore, an increase in force will result in a proportional increase in acceleration, supporting the statement that force is directly proportional to acceleration. Choice B is incorrect as it suggests an inverse relationship, which is not consistent with Newton's second law. Choice C is incorrect because force and acceleration are indeed related as per Newton's second law. Choice D is incorrect as force can cause acceleration or deceleration depending on the direction of the force relative to the motion of the object, but it does not exclusively cause deceleration.

2. She was really looking forward to the picnic, _________ she feared it might rain that afternoon. Which of the following transition words or phrases is more appropriate to complete the sentence above?

• A. after all
• B. likewise
• C. in other words
• D. although

Correct answer: D

Rationale: The correct answer is 'D' - 'although.' This transition word is suitable in the context as it indicates a contrast between the excitement of looking forward to the picnic and the worry about rain. 'After all' (choice A) implies a conclusion or reasoning, which doesn't fit the contrast in the sentence. 'Likewise' (choice B) suggests similarity or agreement, which is opposite to the intended contrast. 'In other words' (choice C) signals clarification or providing more details, which is not needed here. Therefore, 'although' is the best choice to convey the contrast between anticipation and concern.

3. Which of the answer choices best explains the purpose of the parentheses in the sentence?

• A. To offer brief commentary on the subject matter being discussed
• B. To modify or qualify the statement that came immediately before
• C. To identify information that was located using another source
• D. To set off useful information that does not fit the flow of the sentence

Correct answer: D

Rationale: The correct answer is D. Parentheses are used to set off supplementary information (the years of Franz Joseph I's reign) that provides context but does not disrupt the flow of the main sentence. Choice A is incorrect as the purpose of the parentheses in this case is not to offer commentary but to provide additional information. Choice B is incorrect as the parentheses do not modify or qualify the statement before. Choice C is incorrect as the information in the parentheses is not identified as being from another source.

4. Convert 0.004 to a ratio.

• A. 1:250
• B. 4:200
• C. 2:400
• D. 9:200

Correct answer: A

Rationale: To convert 0.004 to a ratio, we can express it as 4/1000, which simplifies to 1/250. Therefore, the correct ratio is 1:250. Choice B (4:200) is incorrect as it simplifies to 1:50, not 1:250. Choice C (2:400) simplifies to 1:200, which is also incorrect. Choice D (9:200) simplifies to a ratio greater than 1:1, which is not equivalent to 1:250.

5. What is the equivalent of 0.3 mg in mcg?

• A. 300 mcg
• B. 30 mcg
• C. 3000 mcg
• D. 3 mcg

Correct answer: A

Rationale: To convert milligrams (mg) to micrograms (mcg), you need to multiply by 1000 since 1 mg is equal to 1000 mcg. Therefore, 0.3 mg x 1000 = 300 mcg. This conversion is crucial in healthcare to ensure accurate medication dosages. Choice B (30 mcg) is incorrect as it represents the conversion of 0.03 mg to mcg. Choice C (3000 mcg) is incorrect as it is the result of multiplying 0.3 mg by 10 instead of 1000. Choice D (3 mcg) is incorrect as it is the result of not multiplying by 1000 to convert milligrams to micrograms.
