1. The word "obscurity" can be replaced with which of the following without changing the meaning?
- A. Prominence
- B. Seclusion
- C. Destruction
- D. Transformation
Correct answer: B
Rationale: Both "obscurity" and "seclusion" imply being hidden or unknown. Prominence, destruction, and transformation do not convey the same meaning.
2. What is the correct way to write "25th anniversary" as a word?
- A. Twenty-fiveth anniversary
- B. Twenty Fiveth Anniversary
- C. Twenty fifth anniversary
- D. twenty-fifth anniversary
Correct answer: D
Rationale: Ordinals (numbers with "th", "st", "nd", etc.) are generally written as words when used before nouns. Option (d) is correct.
3. The phrase "robust ethical frameworks" refers to
- A. Complex algorithms and mathematical models used in AI development.
- B. Comprehensive sets of guidelines and regulations governing AI development and deployment.
- C. Advanced hardware and software systems necessary for building powerful AI systems.
- D. Public education campaigns raising awareness about the potential benefits and risks of AI.
Correct answer: B
Rationale: Ethical frameworks are sets of principles and guidelines that ensure responsible AI development and address potential risks, aligning with B.
4. The epiglottis is a small flap of cartilage located near the base of the tongue. What is its role during swallowing?
- A. Initiates the swallowing reflex
- B. Grinds food into smaller pieces
- C. Covers the trachea to prevent food aspiration
- D. Stores saliva for lubrication
Correct answer: C
Rationale: The epiglottis is a crucial anatomical structure that covers the trachea during swallowing to prevent food aspiration. When we swallow, the epiglottis folds over the trachea, directing food and liquids down the esophagus instead of entering the airway. This action helps to ensure that the food and liquids go to the stomach for digestion and not into the lungs, which can lead to aspiration pneumonia, a serious condition. Therefore, option C, 'Covers the trachea to prevent food aspiration,' is the correct role of the epiglottis during swallowing.
5. What is the final stage of both mitosis and meiosis?
- A. Interphase
- B. Telophase
- C. Cytokinesis
- D. G1 phase
Correct answer: B
Rationale: Rationale: - Interphase (option A) is not the final stage of mitosis or meiosis; it is the phase before cell division where the cell prepares for division by growing and replicating its DNA. - Telophase (option B) is the final stage of both mitosis and meiosis. During telophase, the separated chromosomes reach opposite poles of the cell, the nuclear membrane reforms around each set of chromosomes, and the chromosomes begin to decondense. - Cytokinesis (option C) is the process of dividing the cytoplasm to form two separate daughter cells. While it occurs after telophase, it is not considered the final stage of mitosis or meiosis. - G1 phase (option D) is the first gap phase in the cell cycle, occurring before DNA replication. It is not the final stage of mitosis or meiosis.
6. Reactions requiring light energy to proceed are classified as:
- A. Combustion reactions
- B. Endothermic reactions
- C. Photochemical reactions
- D. Double displacement reactions
Correct answer: C
Rationale: The correct answer is C: "Photochemical reactions." Photochemical reactions are a type of chemical reaction that requires light energy to proceed. During a photochemical reaction, light energy is absorbed by a substance, leading to changes in its chemical structure or properties. This process is different from combustion reactions (A), which involve the rapid combination of a fuel with oxygen to release heat and light energy. Endothermic reactions (B) absorb heat energy, not light energy, to proceed. Double displacement reactions (D) involve the exchange of ions between reactants, but do not specifically require light energy to occur. Therefore, the most appropriate classification for reactions requiring light energy is photochemical reactions.
