1. Which element is a metalloid?

• A. Silicon
• B. Lead
• C. Helium
• D. Aluminum

Correct answer: A

Rationale: The correct answer is 'Silicon.' Silicon is a metalloid, which means it has properties of both metals and nonmetals. It is commonly used in electronic devices due to its semiconductor properties. Lead (Choice B) is a metal, Helium (Choice C) is a noble gas, and Aluminum (Choice D) is a metal.

2. The first law of thermodynamics is a principle of energy conservation. It states that:

• A. Energy can be created or destroyed.
• B. The total entropy of an isolated system always decreases.
• C. Energy can neither be created nor destroyed, only transferred or transformed.
• D. The temperature of a system is directly proportional to its entropy.

Correct answer: C

Rationale: The first law of thermodynamics states that energy cannot be created or destroyed; it can only be transferred or converted from one form to another, ensuring energy conservation in any system. Choice A is incorrect because it goes against the principle of energy conservation. Choice B is incorrect as it refers to the second law of thermodynamics, which states that the total entropy of an isolated system always increases. Choice D is incorrect because the temperature of a system is not directly proportional to its entropy.

3. What is the author's primary purpose for writing the passage on the Amazon Rainforest?

• A. To entertain readers with facts about the rainforest.
• B. To inform readers about the deforestation of the Amazon.
• C. To persuade readers to visit the Amazon Rainforest.
• D. To criticize the farming practices in the Amazon.

Correct answer: B

Rationale: The author's primary purpose for writing the passage on the Amazon Rainforest is to inform readers about the deforestation and environmental challenges facing the Amazon. The passage provides detailed information about the Amazon Rainforest, its biodiversity, the impact of deforestation on the environment, and the dangers associated with the destruction of the rainforest. Choice A is incorrect because the author's goal is not to entertain but to educate readers. Choice C is incorrect as there is no persuasive language used to encourage readers to visit the Amazon Rainforest. Choice D is also incorrect as the passage does not focus on criticizing farming practices but rather on highlighting the environmental threats and consequences of deforestation.

4. A hospital nurse's schedule rotates every 4 days. The nurse works 3 days and has 1 day off. If the nurse's first day off is a Monday, what is the nurse's second day off?

• A. Friday
• B. Saturday
• C. Thursday
• D. Wednesday

Correct answer: A

Rationale: The nurse's schedule repeats every 4 days, with 3 days of work and 1 day off. If the first day off is Monday, then after 4 days (Monday + 4 days), the second day off will fall on Friday. Therefore, the correct answer is A. Choice B (Saturday), C (Thursday), and D (Wednesday) are incorrect as they do not align with the 4-day rotation pattern after the first day off on Monday.

5. Which sentence uses the word 'present' as an adjective?

• A. She gave a present to her friend
• B. She was present at the meeting
• C. She made a present for her friend
• D. The teacher presented the award

Correct answer: B

Rationale: The sentence 'She was present at the meeting' uses 'present' as an adjective. In this context, 'present' describes her state of being at the meeting. The other choices use 'present' as a verb (to give), a noun (a gift), and a verb (to show), making them incorrect in the context of looking for the adjective use of 'present'.
