1. Simplify the expression. Which of the following is correct? (52(3) + 3(-2)^2 / 4 + 3^2 - 2(5 - 8))
- A. 9/8
- B. 87/19
- C. 9
- D. 21/2
Correct answer: B
Rationale: To simplify the expression, apply the order of operations (PEMDAS). Begin by squaring -2 to get 4. Then perform the multiplication and subtraction within parentheses: 52(3) + 3(4)/4 + 9 - 2(5 - 8) = 156 + 12/4 + 9 - 2(3) = 156 + 3 + 9 - 6 = 168 + 3 - 6 = 171 - 6 = 165. Therefore, the correct simplified expression is 165, which is equivalent to 87/19. Choices A, C, and D are incorrect because they do not represent the accurate simplification of the given expression.
2. Define 'friction' in terms of opposing motion.
- A. A force that increases motion
- B. A force that accelerates motion
- C. A force that opposes motion
- D. A force that creates motion
Correct answer: C
Rationale: Friction is a force that opposes motion. When two surfaces are in contact, friction acts in the opposite direction to the motion or the potential motion between the two surfaces. It resists the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. Friction hinders or prevents motion rather than promoting it. Choices A, B, and D are incorrect as they suggest that friction increases, accelerates, or creates motion, which is inaccurate. The correct definition of friction is that it opposes motion, making choice C the most appropriate option.
3. What does Lady Bracknell's interrogation of Jack reveal about the nature of marriage in the society Wilde is critiquing?
- A. It shows that marriage is based on love and personal choice.
- B. It reveals that marriage is a serious, thoughtful decision.
- C. It illustrates that marriage is more about social standing and wealth than love.
- D. It suggests that marriage is an outdated institution.
Correct answer: C
Rationale: Lady Bracknell's interrogation of Jack regarding his suitability as a husband for her daughter Gwendolen reveals that marriage in the society depicted in the play is more about wealth and social status than love. This is evident as Lady Bracknell places great emphasis on Jack's financial background, social connections, and suitability as a match based on these criteria. Choice A is incorrect because Lady Bracknell's focus is not on love or personal choice but on societal expectations and status. Choice B is incorrect as the interrogation highlights superficial considerations rather than portraying marriage as a serious, thoughtful decision. Choice D is also incorrect as the play does not suggest that marriage is outdated, but rather emphasizes its transactional and societal nature in the context of the aristocratic society being critiqued.
4. Which of the following statements about fungi is FALSE?
- A. They can be unicellular or multicellular
- B. They are all parasitic and cause disease in humans
- C. They play a vital role in decomposition and nutrient cycling
- D. Some are used in food production, like mushrooms
Correct answer: B
Rationale: A) This statement is true. Fungi can exist in both unicellular (yeast) and multicellular (molds and mushrooms) forms. B) This statement is false. While some fungi can be parasitic and cause diseases in humans, not all fungi exhibit this behavior. Many fungi are beneficial and play essential roles in ecosystems. C) This statement is true. Fungi are crucial for decomposition and nutrient cycling in ecosystems. They break down organic matter and recycle nutrients back into the environment. D) This statement is true. Some fungi, like mushrooms, are used in food production and are consumed by humans.
5. Which of the following percentages is equivalent to the fraction 3/4?
- A. 57%
- B. 7.50%
- C. 65%
- D. 75%
Correct answer: D
Rationale: To convert a fraction to a percentage, you multiply the fraction by 100. In this case, 3/4 * 100% = 75%. Therefore, the correct answer is D. Choice A (57%) is incorrect as it does not represent the fraction 3/4. Choice B (7.50%) is incorrect as it is not the equivalent percentage of 3/4. Choice C (65%) is incorrect as it does not match the percentage value of 3/4.
