1. Which sentence correctly uses the word 'affect'?

• A. The medication had no effect on the patient's symptoms
• B. The noise did not affect his sleep
• C. The bright light will affect your eyes
• D. The cold weather did not affect her mood

Correct answer: B

Rationale: The correct use of 'affect' is to show influence or make a difference. In this context, 'The noise did not affect his sleep' is the correct usage as noise can impact one's ability to sleep. Choice A is incorrect as 'affect' is commonly confused with 'effect.' Choice C is incorrect as 'affect' is not typically used to refer to the impact of light on eyes. Choice D is incorrect as 'affect' is not typically used to describe the impact of weather on mood.

2. Two objects attract each other with a gravitational force of 12 units. If the distance between them is halved, what is the new force of attraction between the two objects?

• A. 3 units
• B. 6 units
• C. 24 units
• D. 48 units

Correct answer: C

Rationale: The gravitational force between two objects is inversely proportional to the square of the distance between them. When the distance is halved, the new force of attraction will be 12 units x (1/(0.5)^2) = 12 units x 4 = 24 units. Therefore, the correct answer is C. Choice A and B are incorrect as they do not consider the inverse square law of gravitational force. Choice D is incorrect as reducing the distance between the objects does not lead to a squared increase in force.

3. A woman received a bottle of perfume as a present. The bottle contains ½ oz of perfume. How many milliliters is this?

• A. 10 mL
• B. 15 mL
• C. 20 mL
• D. 25 mL

Correct answer: B

Rationale: To convert ounces to milliliters, we know that 1 ounce is approximately 30 mL. Therefore, 0.5 ounces would be half of that, which is 15 mL. So, 0.5 oz of perfume is equal to 15 mL. Choice A (10 mL), Choice C (20 mL), and Choice D (25 mL) are incorrect as they do not reflect the accurate conversion from ounces to milliliters.

4. A 10-kg object moving at 5 m/s has an impulse acted on it causing the velocity to change to 15 m/s. What was the impulse that was applied to the object?

• A. 10 kg⋅m/s
• B. 15 kg⋅m/s
• C. 20 kg⋅m/s
• D. 100 kg⋅m/s

Correct answer: D

Rationale: Impulse is the change in momentum of an object. The initial momentum is calculated as 10 kg × 5 m/s = 50 kg⋅m/s, and the final momentum is 10 kg × 15 m/s = 150 kg⋅m/s. The change in momentum (impulse) is 150 kg⋅m/s - 50 kg⋅m/s = 100 kg⋅m/s. Therefore, the impulse applied to the object is 100 kg⋅m/s. Choices A, B, and C are incorrect because they do not reflect the correct calculation of the impulse based on the change in momentum of the object.

5. Which of the following is not mentioned as a detail in the passage about High Fructose Corn Syrup?

• A. HFCS and sugar share a biological structure.
• B. HFCS is cheaper to use than sugar.
• C. HFCS is now used to sweeten a variety of products.
• D. HFCS contains more calories than aspartame.

Correct answer: D

Rationale: The correct answer is D because the passage does not mention that HFCS contains more calories than aspartame. While the passage discusses the concerns and implications of high fructose corn syrup (HFCS), it does not compare its caloric content to aspartame. Detail A is supported by the passage as both HFCS and sugar share a biological structure. Detail B is also mentioned in the passage, stating that HFCS is cheaper to use than sugar. Detail C is supported by the text, which mentions that HFCS is now used to sweeten a variety of products. However, detail D is never discussed in the passage, making it the correct answer.
