English Grammar
1. The phrase "a bold new world" is an example of
- A. Hyperbole
- B. Oxymoron
- C. Simile
- D. Metaphor
Correct answer: B
Rationale: An oxymoron combines contradictory terms, like "bold new" signifying the unexpected and promising nature of the world.
2. What type of nuclear reaction releases a large amount of energy in a short time?
- A. Radioactivity
- B. Nuclear fission
- C. Nuclear fusion
- D. All of the above
Correct answer: C
Rationale: Nuclear fusion releases a large amount of energy in a short time by combining two light atomic nuclei to form a heavier nucleus. This process is the energy source of the sun and hydrogen bombs. Radioactivity involves the spontaneous emission of particles or energy from an unstable atomic nucleus, while nuclear fission is the splitting of a heavy atomic nucleus into two or more lighter nuclei, also releasing energy. However, nuclear fusion is specifically known for releasing a large amount of energy in a short time.
3. In a chemical reaction, the total amount of:
- A. Matter remains the same
- B. Matter increases
- C. Matter decreases
- D. Energy remains the same
Correct answer: A
Rationale: The Law of Conservation of Mass states that matter cannot be created or destroyed in a chemical reaction, only rearranged
4. Which term describes the ability of a muscle to return to its original length and shape after being stretched or contracted?
- A. Contractility
- B. Elasticity
- C. Extensibility
- D. Excitability
Correct answer: b
Rationale: The correct answer is B: "Elasticity." Elasticity is the term that describes the ability of a muscle to return to its original length and shape after being stretched or contracted. Contractility refers to the muscle's ability to contract forcefully, extensibility is the ability of a muscle to be stretched without being damaged, and excitability is the ability of a muscle to respond to stimuli. In this context, elasticity specifically pertains to the muscle's ability to bounce back to its original form, making it the most appropriate term in relation to the question.
5. Which vitamin is synthesized in the skin upon exposure to sunlight?
- A. Vitamin A
- B. Vitamin C
- C. Vitamin D
- D. Vitamin E
Correct answer: A
Rationale: The correct answer is Vitamin D (C). When the skin is exposed to sunlight, a compound in the skin is converted to Vitamin D. Vitamin A (A) is not synthesized in the skin but is found in foods like carrots and sweet potatoes. Vitamin C (B) is not synthesized in the skin either, but is found in citrus fruits and vegetables. Vitamin E (D) is not synthesized in the skin upon sunlight exposure, but is found in nuts and seeds.
6. Which property of a substance refers to its ability to be stretched into thin wires without breaking?
- A. Conductivity
- B. Viscosity
- C. Ductility
- D. Malleability
Correct answer: c
Rationale: Ductility is the property that describes a substance's ability to be stretched into thin wires without breaking.
