English Grammar
1. Which of the following sentences uses figurative language?
- A. The scientist conducted an experiment.
- B. The child ran like a cheetah.
- C. The book contained many pages.
- D. The teacher explained the concept clearly.
Correct answer: B

2. What is the function of arrector pili muscles?
- A. To control sweat production
- B. To contract and cause goosebumps
- C. To produce sebum
- D. To sense touch
Correct answer: B
Rationale: The correct answer is B: 'To contract and cause goosebumps.' Arrector pili muscles are small muscles attached to hair follicles in the skin. When these muscles contract, they cause the hair to stand upright, resulting in the appearance of goosebumps. This physiological response is a remnant of our evolutionary past when our ancestors had more hair, and the raised hair helped to trap air for insulation or to make them look larger when threatened. Therefore, the function of arrector pili muscles is not to control sweat production (A), produce sebum (C), or sense touch (D), but rather to create the physical response of goosebumps.
3. Biodiversity is important for healthy ecosystems because it:
- A. Increases competition for resources
- B. Provides stability and resilience to disturbances
- C. Slows down nutrient cycling
- D. Reduces the number of decomposers
Correct answer: B
Rationale: Rationale: Biodiversity refers to the variety of living organisms in a particular area. A diverse ecosystem is better able to withstand and recover from disturbances such as natural disasters, climate change, or human impacts. This is because different species play unique roles in the ecosystem, and a higher level of biodiversity means there are more species available to fulfill these roles. For example, if one species is negatively affected by a disturbance, other species may be able to compensate for its loss, maintaining the overall functioning of the ecosystem. Therefore, biodiversity provides stability and resilience to disturbances, making ecosystems healthier and more sustainable.
4. What is the term for the involuntary muscle contractions that move food through the digestive tract?
- A. Segmentation
- B. Peristalsis
- C. Chyme
- D. Emulsification
Correct answer: B
Rationale: The correct answer is B: Peristalsis. Peristalsis is the term used to describe the involuntary muscle contractions that help move food through the digestive tract. These rhythmic contractions occur in the smooth muscles of the digestive system and help propel food and other substances like chyme through the esophagus, stomach, and intestines. Segmentation, choice A, refers to the mixing movements in the intestines that aid in digestion but do not move food along the tract. Chyme, choice C, is the semi-fluid mass of partially digested food that moves from the stomach to the small intestine. Emulsification, choice D, is the process of breaking down fats into smaller droplets to aid in digestion, but it is not directly related to the movement of food through the digestive tract.
5. How can you effectively adapt your writing style to different audiences?
- A. Use the same formal tone regardless of the audience.
- B. Consider the audience's age, background, and level of knowledge.
- C. Rely on jargon and technical terms to sound professional.
- D. Focus on your own voice and writing preferences.
Correct answer: B
Rationale: Effective writing adapts to the audience's needs and background by adjusting vocabulary, tone, and level of detail.
6. Which of the following represents a form of potential energy?
- A. A moving car
- B. A spinning top
- C. A raised hammer
- D. A rolling ball
Correct answer: c
Rationale: A raised hammer possesses potential energy due to its elevated position relative to the ground.
