1. Every morning we would wake up, eat breakfast, and break camp. Which of the following is the correct revision for the sentence?

• A. NO CHANGE
• B. we would wake up, eat breakfast, and break camp.
• C. would we wake up, eat breakfast, and break camp?
• D. we are waking up, eating breakfast, and breaking camp.

Correct answer: B

Rationale: The correct answer is B: 'we would wake up, eat breakfast, and break camp.' The original sentence is a list of actions in the past, so the verb 'break' should also be in the past tense to maintain consistency. Choice A is incorrect because 'broke' is incorrect in this context. Choice C is a question format and does not fit the original sentence structure. Choice D changes the tense to present progressive, which does not match the past tense context of the sentence.

2. Electroencephalography (EEG) measures electrical activity in the brain, primarily reflecting the activity of:

• A. Neurons
• B. Astrocytes
• C. Oligodendrocytes
• D. Microglia

Correct answer: A

Rationale: EEG measures electrical activity in the brain, primarily reflecting the activity of neurons. Neurons are the primary cells responsible for generating electrical impulses and transmitting information in the brain. Astrocytes, oligodendrocytes, and microglia are other types of cells in the brain that have different functions and are not primarily involved in generating the electrical activity measured by EEG. Astrocytes support neuronal function, oligodendrocytes produce myelin to insulate axons, and microglia are involved in immune responses and maintaining brain health, but they do not generate the electrical impulses detected by EEG.

3. What is the equivalent of 0.3 milliliters?

• A. 0.03 ml
• B. 0.3 ml
• C. 3 ml
• D. 30 ml

Correct answer: B

Rationale: 0.3 milliliters is equivalent to 0.3 ml. This is a precise measurement commonly used in medical settings for administering small doses of liquid medication. It is important to understand and recognize the decimal point placement when converting between milliliters and other volume units. Choice A (0.03 ml) is incorrect as it represents a smaller amount than 0.3 ml. Choice C (3 ml) and Choice D (30 ml) are also incorrect as they are larger measurements and do not match the given amount of 0.3 ml.

4. In the table above, how many Heather Gray T-shirts were ordered in a size small in the month of January?

• A. One
• B. Two
• C. Three
• D. Four

Correct answer: A

Rationale: According to the table, one Heather Gray T-shirt in size small was ordered in January. The other choices are incorrect as they do not align with the information provided in the table, which clearly states that only one T-shirt of that description was ordered.

5. Which of the following represents a form of potential energy?

• A. A moving car
• B. A spinning top
• C. A raised hammer
• D. A rolling ball

Correct answer: C

Rationale: A raised hammer represents potential energy as it possesses stored energy due to its position above the ground. When the hammer falls, this potential energy is converted into kinetic energy as it moves. In contrast, options A, B, and D involve objects already in motion, representing kinetic energy. Choice A, a moving car, is in motion and has kinetic energy. Choice B, a spinning top, is also in motion and exhibits kinetic energy. Choice D, a rolling ball, is already moving and thus has kinetic energy. Therefore, only choice C, a raised hammer, is the correct representation of potential energy among the given options.
