Mathematics

1. A water fountain has a spherical base (diameter 50cm) and a cylindrical body (diameter 30cm, height 80cm) on top. What is the total surface area of the fountain (excluding the water surface)?

Correct answer: C

Rationale: Calculate the surface area of the sphere and the cylinder separately, then add them up.

2. Which of the following statements is true regarding a supersaturated solution?

Correct answer: a

Rationale: Supersaturated solutions are unstable and tend to crystallize if disturbed. The other choices do not accurately describe supersaturated solutions.

3. Which of the following statements about prions is TRUE?

Correct answer: A

Rationale: Rationale: A) This statement is true. Prions are infectious agents composed entirely of protein, lacking nucleic acids such as DNA or RNA. They are known for causing neurodegenerative diseases in animals and humans. B) This statement is false. Prions are not easily destroyed by common disinfectants due to their unique structure and resistance to conventional sterilization methods. C) This statement is false. Prions are not a type of antibiotic. They are a distinct class of infectious agents. D) This statement is false. Prions are not live organisms but rather misfolded proteins that can induce abnormal folding in normal proteins, leading to disease.

4. Based on the passage, the author's stance on AI is likely to be

Correct answer: B

Rationale: The emphasis on balancing benefits and risks suggests a cautious and balanced perspective, aligning with B.

5. What is the main consequence of a malfunctioning thyroid gland that produces abnormally low levels of thyroid hormones?

Correct answer: B

Rationale: The correct answer is B: 'Decreased heart rate and body temperature.' When the thyroid gland produces abnormally low levels of thyroid hormones (hypothyroidism), it can lead to a decrease in metabolic rate, resulting in symptoms such as fatigue, weight gain, and feeling cold. A lower metabolic rate can slow down heart rate and decrease body temperature. The other options (A, C, D) are not characteristic of hypothyroidism. Increased energy levels and weight loss, enhanced muscle growth and bone development, and faster metabolism and heightened alertness are more commonly associated with hyperthyroidism, where the thyroid gland produces excess hormones.

6. What is the difference between constructive and destructive interference of waves?

Correct answer: B

Rationale: Constructive interference occurs when peaks of two waves overlap, resulting in a higher combined amplitude. Destructive interference happens when peaks and troughs overlap, cancelling each other out and reducing the overall amplitude.
