1. What is the range in the number of flights the flight attendant made?

• A. 20
• B. 25
• C. 29
• D. 32

Correct answer: B

Rationale: The range is calculated as the difference between the largest and smallest values in a dataset. In this case, the largest number of flights made by the flight attendant in a month was 79, and the smallest number was 54. Therefore, the range is 79 - 54 = 25. Choices A, C, and D are incorrect as they do not reflect the correct calculation of the range based on the given data.

2. What most likely describes the relationship between the author and Alan?

• A. competitive
• B. formal
• C. friendly
• D. caring

Correct answer: C

Rationale: The most likely description of the relationship between the author and Alan is friendly. The author's message to Alan is filled with warmth, concern, and offers of help, indicating a positive and supportive tone. The use of phrases like 'I just wanted to drop you a quick note' and 'Let me know if you want any special treats' reflect a friendly and amicable relationship. Choices A, B, and D are not as suitable as competitive, formal, or caring relationships do not align as strongly with the friendly and supportive nature of the interaction described in the text.

3. 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: Dopamine is the neurotransmitter 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. Acetylcholine is involved in muscle movement and memory, serotonin is linked to mood regulation, and GABA is an inhibitory neurotransmitter that helps reduce neuronal excitability. Therefore, the correct answer is dopamine as it aligns with the neurotransmitter functions related to pleasure, reward, and motivation, distinct from the roles of acetylcholine, serotonin, and GABA.

4. Where is the heart located within the human body cavities?

• A. Dorsal cavity
• B. Ventral cavity
• C. Thoracic cavity
• D. Abdominal cavity

Correct answer: C

Rationale: The heart is located within the thoracic cavity, specifically in the mediastinum, which is the central compartment of the thoracic cavity. The thoracic cavity is part of the ventral cavity, which also includes the abdominal cavity. The dorsal cavity refers to the posterior side of the body and does not contain the heart. The heart is situated in the thoracic cavity between the lungs and above the diaphragm, making option C the correct choice. Therefore, the correct answer is the thoracic cavity (option C). The ventral cavity (option B) includes the thoracic and abdominal cavities, but the heart is specifically situated in the thoracic cavity. The dorsal cavity (option A) is located on the posterior side of the body, not where the heart is positioned. The abdominal cavity (option D) is below the thoracic cavity and houses organs such as the stomach, liver, and intestines, but it does not contain the heart.

5. Which of the following sentences correctly uses a transition word?

• A. Gilda is a hardworking student; therefore, she earned a good grade on her essay.
• B. Gilda is a hardworking student; therefore she earned a good grade on her essay.
• C. Gilda is a hardworking student: therefore, she earned a good grade on her essay.
• D. Gilda is a hardworking student and therefore she earned a good grade on her essay.

Correct answer: A

Rationale: Choice A is the correct answer. 'Therefore' is correctly used as a transition word with proper punctuation in this sentence. In a compound sentence like this, a semicolon is used before the transition word to connect two independent clauses. Choice B is incorrect because it lacks the necessary punctuation to separate the independent clauses. Choice C is incorrect as a colon is not typically used before a transition word in this context. Choice D is incorrect because 'and' does not function as a transition word in this sentence.
