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: Option A "flagrant," emphasizes the severity and noticeable nature of the errors.

2. Which of the following is a characteristic of a solution with a high viscosity?

• A. It flows easily
• B. It has a low resistance to flow
• C. It has a high resistance to flow
• D. It does not mix with other liquids

Correct answer: c

Rationale: Solutions with high viscosity have a high resistance to flow. The other choices do not accurately describe high viscosity.

3. Based on the information provided, which statement is LEAST likely to be supported by the author?

• A. Energy storage technologies play a critical role in the future of renewable energy utilization.
• B. Smart grids can improve the reliability and efficiency of the electricity grid.
• C. Continued reliance on fossil fuels hinders long-term climate change mitigation goals.
• D. Technological advancements offer solutions to overcome challenges associated with renewable energy.

Correct answer: B

Rationale: While the passage mentions smart grids, its primary focus is on managing the intermittency of renewable energy, making B the least likely statement the author would strongly support.

4. Which neurotransmitter is associated with pleasure, reward, and motivation, and is often implicated in conditions such as addiction?

• A. Acetylcholine
• B. Dopamine
• C. Serotonin
• D. GABA (Gamma-aminobutyric acid)

Correct answer: b

Rationale: The correct answer is B: Dopamine. Dopamine is a neurotransmitter that is commonly associated with pleasure, reward, and motivation. It plays a crucial role in the brain's reward system and is often implicated in conditions such as addiction. Dopamine is released in response to rewarding stimuli, reinforcing behaviors that lead to pleasure. Acetylcholine is involved in muscle contraction and memory, not pleasure and reward. Serotonin is known for regulating mood and emotions, while GABA is an inhibitory neurotransmitter that helps reduce neural activity. Therefore, dopamine is the neurotransmitter most closely linked to pleasure, reward, and motivation in the brain.

5. Which word correctly completes the sentence: "He was _____ by the kindness of strangers."

• A. affected
• B. infected
• C. effected
• D. defected

Correct answer: C

Rationale: "Effected" means to produce a result or impression, aligning with the emotional impact of the strangers' kindness.

6. The stratum corneum, the outermost layer of the epidermis, is primarily composed of:

• A. Keratinized dead cells
• B. Melanocytes
• C. Langerhans cells
• D. Merkel cells

Correct answer: A

Rationale: The correct answer is A: 'Keratinized dead cells.' The stratum corneum is the outermost layer of the epidermis and is mainly composed of keratinized dead cells. These cells are flattened, fully keratinized, and provide a protective barrier for the skin against environmental factors such as pathogens, UV radiation, and water loss. Melanocytes (Option B), Langerhans cells (Option C), and Merkel cells (Option D) are all important components of the epidermis but are not the primary constituents of the stratum corneum. Melanocytes produce melanin, Langerhans cells are involved in the immune response, and Merkel cells are associated with the sense of touch.
