1. Which sentence avoids a dangling modifier?
- A. Walking down the street, a bird swooped down from a tree.
- B. Having finished the report, it was time for lunch.
- C. Reading the book, I learned a lot about ancient history.
- D. Exhausted from the hike, the tent was a welcome sight.

2. The element responsible for the green color of leaves is:
- A. Magnesium
- B. Iron
- C. Copper

Correct answer: A
Rationale: Magnesium is the central element of chlorophyll, the pigment responsible for photosynthesis
3. Which of the following describes a scalar quantity?
- A. Velocity
- B. Acceleration
- C. Force
- D. Speed

4. What is the protective sac surrounding the testes in the male reproductive system?
- A. Vas deferens
- B. Scrotum
- C. Epididymis
- D. Urethra
Correct answer: B
Rationale: The correct answer is B: Scrotum. The scrotum is the protective sac surrounding the testes in the male reproductive system. It houses and protects the testes, helping to regulate their temperature for optimal sperm production. The vas deferens is a duct that carries sperm from the testes to the urethra. The epididymis is a coiled tube where sperm mature and are stored. The urethra is a tube that carries urine from the bladder and semen from the reproductive system. Therefore, the scrotum is the specific structure that directly surrounds and protects the testes in the male reproductive system.
5. The innate immune system provides:
- A. Nonspecific, immediate defense against pathogens
- B. Specific, long-term immune response through memory cells
- C. Both (a) and (b)
- D. Neither (a) nor (b)
Correct answer: A
Rationale: The correct answer is A: 'Nonspecific, immediate defense against pathogens.' The innate immune system is the body's first line of defense against pathogens and provides a rapid, nonspecific response. It includes physical barriers like the skin, chemical barriers like stomach acid, and cellular responses like inflammation. This system does not involve memory cells or provide long-term immunity, which are characteristics of the adaptive immune system. Therefore, option A accurately describes the function of the innate immune system as a quick and nonspecific defense mechanism.
6. A garden bed has a side length of 8 meters. What is its perimeter?
- A. 16m
- B. 24m
- C. 32m
- D. 64m
Correct answer: C
Rationale: : Since all sides are equal, multiply the side length by 4: perimeter = 4 * side length = 4 * 8m = 32m.
