English Grammar

1. What is the best way to revise the sentence: "Her eyes glistened with tears in the moonlight"?

Correct answer: C

Rationale: Option C rearranges the elements for smoother flow and emphasis on the tears.

2. Which cartilage type allows for smooth movement at joints and absorbs shock?

Correct answer: A

Rationale: The correct answer is A: Hyaline cartilage. Hyaline cartilage is the most abundant type of cartilage in the body and is found in the joints, providing a smooth surface for movement. It also acts as a shock absorber, cushioning the joints during activities. Fibrocartilage is found in intervertebral discs and provides strength and support, but it is not as effective at absorbing shock as hyaline cartilage. Elastic cartilage is found in the external ear and epiglottis, providing flexibility and maintaining shape, but it does not have the same shock-absorbing properties as hyaline cartilage. Therefore, hyaline cartilage is the best choice for a cartilage type that allows for smooth movement at joints and absorbs shock.

3. The author expresses concern about the...

Correct answer: B

Rationale: The passage's focus on managing the intermittency of renewable energy due to weather conditions implies concern about B.

4. 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.

5. Which term refers to the condition where a muscle shortens in length while generating force, leading to movement at a joint?

Correct answer: d

Rationale: The correct answer is D: Concentric contraction. Concentric contraction occurs when a muscle shortens in length while generating force, resulting in movement at a joint. This type of contraction is commonly seen when lifting a weight in a bicep curl, for example. Isometric contraction, option A, refers to when the muscle generates force without changing length, eccentric contraction, option B, is when the muscle lengthens while generating force, and isotonic contraction, option C, involves the muscle maintaining a constant tension while changing length. Therefore, in the context of muscle movement and joint action, concentric contraction best describes the condition described in the question.

6. What is the main function of calcitonin, a hormone produced by the thyroid gland?

Correct answer: D

Rationale: The correct answer is D: 'Lower blood calcium levels.' Calcitonin is a hormone produced by the thyroid gland that helps regulate calcium levels in the blood. It works by inhibiting the breakdown of bone, which in turn lowers the amount of calcium released into the bloodstream. This process helps to decrease blood calcium levels when they are too high. Options A, B, and C are not functions of calcitonin; instead, they are more closely associated with other hormones such as thyroid hormones, vitamin D, and growth hormone, respectively.
