1. What is the formula for calculating density?

• A. Density = Volume / Mass
• B. Density = Mass × Volume
• C. Density = Mass / Volume
• D. Density = Volume - Mass

Correct answer: A

Rationale: Density is defined as the amount of mass in a given volume. The formula for calculating density is Density = Mass / Volume. This means that you divide the mass of an object by its volume to determine its density. Therefore, the correct formula for calculating density is Density = Volume / Mass. Choice A is correct because density is calculated by dividing the volume by the mass. Choices B, C, and D are incorrect because they do not represent the correct relationship between mass and volume in calculating density.

2. What is the central idea of this passage?

• A. It introduces certain insects that transition from water to air.
• B. It describes how insects adapt to their environment.
• C. It discusses the significance of insects in ecosystems.
• D. It highlights the duality of insect life.

Correct answer: C

Rationale: The central idea of the passage is to highlight the significance of understanding insects in ecosystems, not just focusing on their adaptability or life transitions. Choice A is incorrect as the passage does not introduce specific insects transitioning from water to air. Choice B is incorrect as the main focus is not solely on how insects adapt to their environment, but on their broader role in ecosystems. Choice D is incorrect as the passage does not discuss the duality of insect life, but rather their importance in the ecosystem.

3. What is the largest part of the brain and is responsible for higher functions like thinking, memory, and learning?

• A. Brainstem
• B. Cerebellum
• C. Cerebrum
• D. Thalamus

Correct answer: C

Rationale: The cerebrum is the correct answer. It is the largest part of the brain and is responsible for higher functions like thinking, memory, and learning. The brainstem (option A) is responsible for basic life functions such as breathing and heart rate, not higher cognitive functions. The cerebellum (option B) is responsible for coordination and balance, not higher cognitive functions. The thalamus (option D) acts as a relay station for sensory information, but it is not the largest part of the brain nor responsible for higher cognitive functions.

4. What is the best definition of the underlined word in the selection below, taken from the third paragraph of the passage? 'You should try to be aware of your consumption of water and energy.'

• A. Using the greatest amount
• B. Illness of the lungs
• C. Using the least amount
• D. Depletion of goods

Correct answer: D

Rationale: In this context, 'consumption' refers to the use or depletion of resources like water and energy. It is not about using the greatest amount (choice A) or the least amount (choice C) but about being mindful of how much you use to avoid depletion. 'Illness of the lungs' (choice B) is completely unrelated to the context of resource conservation discussed in the passage.

5. Which of the following compound sentences is punctuated correctly?

• A. The Forlows would be spending two weeks in Greece and Turkey.
• B. She was awake the minute the sun came up; although she had been up late the night before.
• C. Diana stepped out into the rain, but she had to turn immediately back inside for an umbrella.
• D. Aziz was astonished; he had never seen horses in the wild before.

Correct answer: D

Rationale: Choice D is the correct answer because it correctly punctuates the compound sentence with a semicolon separating the two independent clauses. The use of a semicolon is appropriate when two closely related independent clauses are joined without a coordinating conjunction. Choices A, B, and C have incorrect punctuation or conjunction usage. Choice A incorrectly uses a comma before 'and,' while Choice B uses 'though' which is not the best conjunction to join the two clauses. Choice C also lacks appropriate punctuation to separate the two independent clauses.
