English Grammar
1. Identify the determiner in the following sentence: A few birds chirped happily in the branches of the tall tree.
- A. happily
- B. ranches
- C. few
- D. tree
Correct answer: C
Rationale: Determiners specify the quantity or identity of a noun. "Few" indicates the number of birds.
2. A car skids on a wet road. What is the main force preventing the car from stopping?
- A. Friction
- B. Gravitational force
- C. Normal force from the road
- D. Air resistance
Correct answer: A
Rationale: Friction opposes the motion of the car, trying to bring it to a stop. However, due to the wet surface, the friction force is not enough to overcome the car's inertia.
3. Which of the following is NOT a mechanism of evolution?
- A. Natural selection
- B. Genetic drift
- C. Lamarckism
- D. Mutation
Correct answer: C
Rationale: Rationale: A) Natural selection is a mechanism of evolution where individuals with advantageous traits are more likely to survive and reproduce, passing on those traits to the next generation. B) Genetic drift is a mechanism of evolution that occurs due to random changes in allele frequencies in a population. C) Lamarckism, also known as the inheritance of acquired characteristics, is a discredited theory that suggests organisms can pass on traits acquired during their lifetime to their offspring. This mechanism has been largely rejected by the scientific community. D) Mutation is a mechanism of evolution that introduces new genetic variation into a population, which can lead to the emergence of new traits and adaptations over time.
4. According to Newton's third law of motion, if you push against a wall with a certain force, the wall will push back with:
- A. A smaller force
- B. An equal force
- C. A greater force
- D. No force at all
Correct answer: b
Rationale: Newton's third law states that for every action, there is an equal and opposite reaction.
5. Which of the following is NOT a common site for lymph nodes?
- A. Groin
- B. Armpit
- C. Neck
- D. Liver
Correct answer: D
Rationale: The correct answer is D: 'Liver.' Lymph nodes are small, bean-shaped structures that are part of the lymphatic system. They are commonly found in areas such as the groin, armpit, and neck, where they help filter and trap harmful substances. The liver, while an important organ in the body, does not typically contain lymph nodes. Therefore, it is not a common site for lymph nodes. Understanding the locations of lymph nodes in the body is important for identifying potential sources of infection or cancer when assessing patients.
6. What is the main component that gives bones their rigidity and hardness?
- A. Collagen
- B. Calcium phosphate
- C. Cartilage
- D. Ligaments
Correct answer: B
Rationale: The main component that gives bones their rigidity and hardness is calcium phosphate, which is a mineral compound found in bone tissue. While collagen is a protein that provides flexibility and strength to bones, it is the calcium phosphate that primarily contributes to the hardness and rigidity of bones. Cartilage is a connective tissue that cushions joints and helps with movement, while ligaments are fibrous tissues that connect bones to other bones. Therefore, calcium phosphate is the correct answer as it directly relates to the rigid and hard nature of bones.
