1. Which word choice best fits the blank: 'Her research paper was riddled with _____ errors.'

• A. flagrant (obvious and inexcusable)
• B. cursory (superficial)
• C. innocuous (harmless)
• D. meticulous (carefully detailed)

Correct answer: A

Rationale: The word 'flagrant' in option A is the most appropriate choice for the blank because it conveys the idea of errors that are glaringly obvious and inexcusable. In this context, the research paper is described as being 'riddled with errors,' suggesting a significant amount of mistakes that stand out and are severe. Choice B, 'cursory,' meaning superficial, does not accurately describe the seriousness of the errors. Choice C, 'innocuous,' meaning harmless, is the opposite of what is implied by the sentence. Choice D, 'meticulous,' meaning carefully detailed, is the opposite of what is needed to describe errors in this context.

2. Which of the following words from the sentence above has a negative connotation?

• A. Contained
• B. Shocked
• C. Complimentary
• D. Reportedly

Correct answer: B

Rationale: The word 'shocked' has a negative connotation as it implies a strong feeling of surprise or dismay. In the context of the provided extract, the word 'shocked' would be fitting to describe the reaction of individuals witnessing the sudden outbreak of violence during the skirmish at Lexington and Concord. The other choices do not carry a negative connotation in this context: 'Contained' is neutral, 'Complimentary' is positive, and 'Reportedly' is neutral.

3. A person pushes a box across a floor with a constant force. The box eventually comes to a stop due to friction. What happens to the work done by the person?

• A. It increases as the box moves further.
• B. It decreases as the box slows down.
• C. It remains constant throughout the motion.
• D. It becomes zero once the box stops.

Correct answer: D

Rationale: Work done is defined as the product of the force applied and the distance moved in the direction of the force. In this scenario, when the box comes to a stop, the displacement becomes zero, leading to zero work done by the person. Choice A is incorrect as the work done is not increasing, but rather decreasing as the box slows down. Choice B is incorrect because the work done does not decrease as the box slows down; it becomes zero when the box stops. Choice C is incorrect as the work done is not constant but decreases to zero when the box stops.

4. Which of the following neurotransmitters slows down the activity of neurons to prevent overexcitation?

• A. Acetylcholine
• B. Dopamine
• C. GABA
• D. Serotonin

Correct answer: C

Rationale: The correct answer is C: GABA (gamma-aminobutyric acid). GABA is an inhibitory neurotransmitter that slows down neuronal activity, helping to prevent overexcitation in the brain. It counterbalances the effects of excitatory neurotransmitters like glutamate, playing a crucial role in maintaining the balance of neuronal activity in the brain. Acetylcholine (Choice A) is primarily an excitatory neurotransmitter involved in muscle movement and cognitive functions. Dopamine (Choice B) plays a role in reward-motivated behavior and motor control. Serotonin (Choice D) is involved in regulating mood, appetite, and sleep but is not primarily responsible for slowing down neuronal activity to prevent overexcitation.

5. Which of the following blood vessels carries oxygenated blood away from the heart?

• A. Pulmonary artery
• B. Aorta
• C. Superior vena cava
• D. Inferior vena cava

Correct answer: B

Rationale: The aorta is the correct answer because it is the main artery in the body that carries oxygenated blood away from the heart to the rest of the body. The pulmonary artery carries deoxygenated blood from the heart to the lungs for oxygenation. The superior and inferior vena cava are veins that carry deoxygenated blood from the body back to the heart. Therefore, choices A, C, and D are incorrect as they do not carry oxygenated blood away from the heart.
