1. Why was receiving a white elephant considered a burden in ancient Siam?

• A. People tried to avoid receiving it, as it was a burden.
• B. It was a symbol of honor and wealth.
• C. It was used in ceremonial processes.
• D. The people greatly desired a white elephant as a gift.

Correct answer: A

Rationale: Receiving a white elephant in ancient Siam was considered a burden because the animal, being sacred, couldn't be used for work like other elephants. The recipient had to bear the cost of feeding the elephant large amounts of fruit and maintaining it in a lavish manner. The ruler's displeasure if the gift was not accepted graciously added to the pressure. This financial strain often led recipients to financial ruin. Therefore, people tried to avoid receiving a white elephant to prevent these financial consequences. Choice B is incorrect because the white elephant was not considered a symbol of honor and wealth but rather a burden. Choice C is incorrect as the white elephant was not primarily used in ceremonial processes but was a gift that came with financial responsibilities. Choice D is incorrect as the passage does not mention that people greatly desired a white elephant as a gift, but rather the opposite.

2. From which component do RNA and DNA derive their names?

• A. From the sugar each contains
• B. From the structure of their nucleotides
• C. From the information they transfer
• D. From their formative processes

Correct answer: A

Rationale: RNA and DNA derive their names from the sugar each contains. RNA stands for Ribonucleic Acid, with 'ribo' indicating the ribose sugar in its structure. DNA stands for Deoxyribonucleic Acid, with 'deoxyribo' referring to the deoxyribose sugar in its structure. The sugars in RNA and DNA molecules distinguish them and are the basis for their names. Choices B, C, and D are incorrect as they do not accurately explain how RNA and DNA derive their names.

3. Which hormone is responsible for regulating the sleep-wake cycle?

• A. Melatonin
• B. Thyroxine
• C. Insulin
• D. Cortisol

Correct answer: A

Rationale: Melatonin, produced by the pineal gland, regulates the sleep-wake cycle by responding to light and darkness in the environment. It plays a crucial role in signaling the body when it's time to sleep and wake up, helping to establish and maintain a healthy circadian rhythm. Thyroxine, Insulin, and Cortisol do not directly regulate the sleep-wake cycle, making them incorrect choices for this question.

4. What can be inferred about the author's reaction to different voices?

• A. Be an experienced public speaker
• B. Prefer shrill, grating, and brassy voice
• C. Have no particular reactions to different voices
• D. nan

Correct answer: C

Rationale: Based on the extract provided, the author discusses the effects of different voice qualities on others but does not express any preference or reaction towards specific voices. The author emphasizes the negative impact of harsh tones and provides insights into how voice qualities can influence perceptions. As a result, it can be inferred that the author has no particular reactions to different voices. Choices A and B are incorrect as there is no mention of the author's public speaking experience or preference for specific voice qualities in the passage.

5. Which organelle is responsible for energy production in the cell?

• A. Nucleus
• B. Mitochondria
• C. Ribosomes
• D. Endoplasmic reticulum

Correct answer: B

Rationale: Mitochondria are the organelles responsible for energy production in the cell. They generate energy through cellular respiration, producing ATP, which is the primary energy currency of the cell. Known as the powerhouse of the cell, mitochondria play a vital role in meeting the energy demands of various cellular processes. The nucleus is responsible for storing genetic material, not energy production. Ribosomes are involved in protein synthesis, not energy production. The endoplasmic reticulum is involved in protein and lipid synthesis, as well as detoxification, but it is not primarily responsible for energy production.
