1. Which phenomenon describes the bending of light as it travels from one medium to another with differing densities?

• A. Reflection
• B. Refraction
• C. Diffraction
• D. Dispersion

Correct answer: B

Rationale: Refraction is the phenomenon that describes the bending of light as it travels from one medium to another with differing densities. This bending occurs due to the change in speed of light as it moves from one medium to another, causing the light rays to change direction. Reflection refers to the bouncing back of light when it hits a surface, diffraction is the bending of light around obstacles, and dispersion is the separation of light into its different colors. Therefore, in the context of light moving through different media, refraction accurately describes the observed bending phenomenon.

2. What is the solution to 4 x 7 + (25 – 21)²?

• A. 512
• B. 36
• C. 44
• D. 22

Correct answer: C

Rationale: To find the solution, first solve the expression inside the parentheses: 25 - 21 = 4. Then, square the result from the parentheses: 4² = 16. Next, perform the multiplication: 4 x 7 = 28. Finally, add the results: 28 + 16 = 44. Therefore, the correct answer is 44. Choice A (512), Choice B (36), and Choice D (22) are incorrect as they do not follow the correct order of operations for solving the given mathematical expression.

3. How do DNA and RNA function together as part of the human genome?

• A. DNA carries genetic information from RNA to the cell cytoplasm.
• B. RNA carries genetic information from DNA to the cell cytoplasm.
• C. DNA and RNA carry genetic information from the cell nucleus to the cytoplasm.
• D. DNA and RNA do not interact within the cell.

Correct answer: B

Rationale: The correct answer is B. RNA acts as a messenger carrying genetic instructions from the DNA in the nucleus to the cytoplasm, where proteins are synthesized. This process is known as transcription and translation, where DNA provides the blueprint for protein synthesis, and RNA delivers this information to the cellular machinery in the cytoplasm. Choice A is incorrect as it inaccurately states that DNA carries genetic information from RNA, which is the opposite of the actual flow of information. Choice C is incorrect as it suggests that both DNA and RNA together carry genetic information from the nucleus to the cytoplasm, which is not accurate. Choice D is incorrect as DNA and RNA do interact within the cell, playing crucial roles in genetic information processing and protein synthesis.

4. Even without Franz Ferdinand's assassination ... Which of the following most logically completes the passage?

• A. A war between the world powers was extremely likely.
• B. World War I never would have happened.
• C. England, France, and Russia would have started the war.
• D. Austria would have started the war.

Correct answer: A

Rationale: The correct answer is A. Given the alliances and tensions at the time, the assassination was simply the trigger in an already volatile situation, making war highly likely. Choice B is incorrect because the alliances and existing tensions would likely have led to a conflict even without the assassination. Choice C is incorrect as it wrongly implies that only these three countries were involved in the conflict. Choice D is incorrect as Austria alone starting the war doesn't consider the broader context of alliances and power dynamics among the world powers.

5. Which of the statements reflect information that one could reasonably infer based on the author's tone?

• A. The author's tone is persuasive and attempts to call the audience to action.
• B. The author's tone is passionate due to excitement over the subject and personal narrative.
• C. The author's tone is informative and exhibits interest in the subject of the study.
• D. The author's tone is somber, depicting some anger at the state of insect larvae.

Correct answer: A

Rationale: The statement 'The author's tone is persuasive and attempts to call the audience to action' reflects information that one could reasonably infer based on the author's tone. The use of persuasive language and an attempt to call the audience to action suggests that the author is trying to convince or motivate the readers to take a specific course of action. This inference is based on the author's choice of words and the overall tone of the text. Choice B is incorrect as it introduces the idea of excitement and personal narrative, which are not clearly indicated in the author's tone. Choice C is incorrect as although the author may be informative, the focus is on persuasive language rather than merely providing information. Choice D is incorrect as it introduces emotions like anger and somberness, which are not explicitly conveyed in the author's tone.
