1. What property of a wave remains unchanged when it passes from one medium to another with the same speed?
- A. Frequency
- B. Wavelength
- C. Amplitude
- D. Speed
Correct answer: d
Rationale: The speed of a wave remains constant when passing from one medium to another with the same speed.
2. Which sentence uses the pronoun "they" correctly?
- A. Her friends told her they liked her new haircut.
- B. Sarah and I, they went to the movies.
- C. They gave the awards to whomever deserved them.
- D. The birds, they were singing in the trees.
Correct answer: A
Rationale: Option A agrees with the closest noun, "friends."
3. When choosing a color palette for a presentation, it's best to:
- A. Use as many vibrant colors as possible to grab attention.
- B. Stick to a monochrome palette for a minimalist look
- C. Select complementary colors that create harmony and contrast.
- D. Use the same colors as your company logo for consistency.
Correct answer: C
Rationale: While both branding consistency and minimalism have their place, presentations benefit from utilizing complementary colors for visual interest and clarity.
4. Which statement correctly describes the concept of ionization energy?
- A. The energy required to remove an electron from an outermost shell.
- B. The energy released when an electron bonds with an atom.
- C. The total energy possessed by all electrons in an atom.
- D. The energy needed to change an atom's nucleus.
Correct answer: A
Rationale: The energy required to remove an electron from an outermost shell. Ionization energy varies depending on the element and electron configuration, indicating its difficulty to lose electrons and influencing its reactivity.
5. The gradual change in a species over time in response to environmental pressures is best described by:
- A. Punctuated equilibrium (rapid bursts of evolution)
- B. Gradualism (slow and continuous change)
- C. Founder effect (genetic drift in a small population)
- D. Adaptive radiation (rapid diversification of a species)
Correct answer: B
Rationale: Rationale: A) Punctuated equilibrium refers to rapid bursts of evolution followed by long periods of stability, rather than gradual change over time in response to environmental pressures. B) Gradualism is the process by which species evolve through slow and continuous changes over time in response to environmental pressures. This gradual change can lead to the development of new traits and adaptations. C) Founder effect is a type of genetic drift that occurs when a small group of individuals establishes a new population, leading to a loss of genetic variation compared to the original population. It does not specifically describe the gradual change in a species over time. D) Adaptive radiation is the rapid diversification of a species into a variety of forms to exploit different ecological niches, but it does not specifically refer to the gradual change in response to environmental pressures. Therefore, the best description of the gradual change in a species over time in response to e
6. The sentence "The audience was captivated by the speaker's compelling story" implies that the audience:
- A. Was bored and disinterested.
- B. Found the story confusing.
- C. Was completely absorbed and engaged.
- D. Disagreed with the speaker's message.
Correct answer: C
Rationale: "Captivated" suggests the audience was completely held by the speaker's story.
