1. What is the name for the process where a solid changes directly into a gas?

Correct answer: B

Rationale: Sublimation is the process by which a solid directly transforms into a gas without passing through the liquid phase. This occurs when the atmospheric pressure is lower than the vapor pressure of the solid, causing it to transition to a gas state. Choice A, evaporation, is the process where a liquid changes into a gas, not a solid. Choice C, condensation, is the opposite process where gas changes into a liquid. Choice D, melting, is the process where a solid changes into a liquid, not a gas.

2. Which of the following sentences follows the rules of capitalization?

Correct answer: B

Rationale: In sentence B, "Ukrainians" is capitalized because it is referring to a specific group of people, and "Malanka" is also capitalized as it is a holiday name. This follows the rules of capitalization for proper nouns. Choices A, C, and D contain correct capitalization, but they also include additional capitalizations that are unnecessary. For instance, in choice A, "African white-backed vultures" should not be capitalized unless it is part of a proper noun or a title. In choice C, while "Neptune" and "Earth" should be capitalized as they are names of celestial bodies, the word "sun" is not capitalized unless it is used as part of the proper noun "Sun." Choice D correctly capitalizes proper nouns like "Edward Jenner" and "Immunology," but the general terms like "Father" and "vaccine" do not need capitalization unless they are part of a title or a specific name.

3. When light reflects from a surface, what determines the angle of reflection?

Correct answer: C

Rationale: The angle of reflection is determined by the angle of incidence according to the law of reflection, which states that the angle of incidence is equal to the angle of reflection. When light reflects off a surface, the angle at which it strikes the surface (angle of incidence) is the key factor in determining the angle at which it reflects (angle of reflection). The material of the surface, the wavelength of the light, and the intensity of the light do not directly influence the angle of reflection in this context. Therefore, the correct answer is the angle of incidence (Choice C). The material of the surface (Choice A) does affect other properties like reflectivity but does not directly determine the angle of reflection. The wavelength of the light (Choice B) determines its color or frequency but not the angle of reflection. The intensity of the light (Choice D) is related to the brightness of the light but does not dictate the angle at which light reflects from a surface.

4. According to the affixes, which of the following words refers to the love of books?

Correct answer: B

Rationale: The correct answer is 'Bibliophile.' The term 'biblio-' is an affix that refers to books, and '-phile' denotes love or attraction. Therefore, 'bibliophile' specifically means a person who loves or collects books. Choice A, 'Logophile,' while containing the '-phile' suffix denoting love, relates to words instead of books. Choices C and D, 'Discophile' and 'Audiophile,' are incorrect as they respectively pertain to music records and sound systems, not books.

5. What does the word 'wise' in this passage most closely mean?

Correct answer: A

Rationale: In the context of the passage, the word 'wise' refers to the 'manner' in which the sun-fish builds its hatchery. It describes the careful and skillful way in which the mother sun-fish constructs and provides for her offspring. Choice B, 'Knowledge,' is incorrect as the word 'wise' does not specifically imply knowledge in this passage. Choice C, 'Shrewd,' is incorrect as it suggests cleverness or astuteness, which is not the intended meaning here. Choice D, 'Ignorance,' is the opposite of 'wise' and does not align with the context of the passage.
