1. What is the author's reason for writing the passage on the White Elephant?

• A. To inform readers about Thailand's historical customs.
• B. To entertain readers with the origins of the term 'white elephant.'
• C. To explain the tradition of giving white elephants.
• D. To criticize the tradition of giving white elephants as gifts.

Correct answer: C

Rationale: The correct answer is C: 'To explain the tradition of giving white elephants.' The passage provides historical context about the practice of giving white elephants as gifts in ancient Siam, now Thailand. It explains how white elephants were considered sacred, could not be put to work, and became a burden to the recipients. The author's purpose is to shed light on this tradition and its implications, not to inform readers about Thailand in general (choice A), entertain with fun facts (choice B), or criticize the tradition (choice D). Choices A and B are incorrect because the passage focuses specifically on the tradition of giving white elephants, not on broader aspects of Thailand or entertainment. Choice D is incorrect because the passage does not criticize the tradition but rather provides a factual account of its historical significance.

2. If a horse can trot around a track twice in 10 minutes, how many times will it circle the track at that same speed in half an hour?

• A. 3 times
• B. 5 times
• C. 6 times
• D. 10 times

Correct answer: C

Rationale: If a horse can trot around a track twice in 10 minutes, it completes one circle in 5 minutes. To determine how many times it will circle the track in half an hour (30 minutes), divide the total time by the time taken for one circle: 30 minutes / 5 minutes per circle = 6 times. Therefore, the horse will circle the track 6 times at the same speed in half an hour. Choice A, 3 times, is incorrect as it does not consider the correct time taken for a single circle. Choice B, 5 times, is incorrect as it miscalculates the total number of circles within half an hour. Choice D, 10 times, is incorrect as it overestimates the number of circles the horse can complete in the given time frame.

3. Which of the following substances is a base?

• A. Water
• B. Sodium chloride
• C. Ammonia
• D. Salt

Correct answer: C

Rationale: The correct answer is 'Ammonia' (Choice C) as it is a common example of a base. Bases are substances that release hydroxide ions (OH-) in aqueous solutions, helping to increase the pH level. Ammonia is a weak base that can accept a proton (H+) to form ammonium hydroxide. In contrast, water (Choice A), sodium chloride (Choice B), and salt (Choice D) are not bases; water is neutral, while sodium chloride and salt are neutral compounds composed of a cation and an anion.

4. How many amino acids are essential for human life?

• A. 22
• B. 20
• C. 18
• D. 24

Correct answer: B

Rationale: There are 20 essential amino acids required for human life. These amino acids cannot be synthesized by the body and must be obtained through the diet. They play crucial roles in various physiological functions and are necessary for protein synthesis and overall health. Choice A is incorrect because there are not 22 essential amino acids. Choice C is incorrect as there are more than 18 essential amino acids. Choice D is incorrect as there are not 24 essential amino acids for human life.

5. The new manager was easy to get along with. How would you describe the new manager based on this sentence?

• A. Affable (friendly)
• B. Tortuous
• C. Apathetic
• D. Sacrosanct

Correct answer: A

Rationale: The correct choice is A - Affable (friendly). Affable means friendly and easy to get along with, which aligns with the description of the new manager in the sentence. Choice B, Tortuous, means twisting or complicated, which does not describe the manager's demeanor. Choice C, Apathetic, means showing no interest or enthusiasm, which is the opposite of the manager being easy to get along with. Choice D, Sacrosanct, means holy or sacred, which is not relevant to the context of the sentence.
