English Grammar

1. Which sentence uses the past perfect tense correctly?

Correct answer: A

Rationale: Option A expresses an action ("party began") completed before another past action ("I arrived").

2. Which of the following is the main function of the small intestine?

Correct answer: B

Rationale: Rationale: The small intestine is a crucial part of the digestive system where the majority of nutrient absorption takes place. It is lined with tiny finger-like projections called villi that increase the surface area for absorption. The small intestine absorbs nutrients such as carbohydrates, proteins, fats, vitamins, and minerals from the digested food into the bloodstream to be transported to cells throughout the body for energy, growth, and repair. Options A, C, and D do not accurately describe the main function of the small intestine.

3. Which of the following substances is typically a good conductor of electricity when dissolved in water?

Correct answer: b

Rationale: Ionic compounds like sodium chloride dissociate into ions in water, making the solution conductive. The other choices do not typically conduct electricity in water.

4. Vaccines work by:

Correct answer: B

Rationale: The correct answer is B: Introducing weakened or inactive versions of pathogens to trigger an immune response. Vaccines work by exposing the immune system to a harmless version of a pathogen, which allows the body to recognize and develop a defense against the pathogen without causing illness. This process stimulates the immune system to produce memory cells that can quickly recognize and attack the pathogen if encountered in the future. Vaccines do not directly kill pathogens (option A) or immediately stimulate the production of specific antibodies (option C). Therefore, option B is the most accurate description of how vaccines work.

5. Which element is used in jewelry due to its malleability and resistance to tarnish?

Correct answer: C

Rationale: Gold's properties make it ideal for crafting durable and aesthetically pleasing jewelry

6. Which hormone is crucial for stimulating sperm production in males?

Correct answer: C

Rationale: The correct answer is C: Testosterone. Testosterone is the primary male sex hormone and is crucial for stimulating sperm production in males through the process of spermatogenesis. It is produced in the testes and plays a key role in the development and maintenance of male reproductive tissues, including the testes and prostate. Estrogen and progesterone are primarily female sex hormones, while insulin regulates blood sugar levels and metabolism. Therefore, testosterone is the hormone specifically responsible for stimulating sperm production in males.
