1. Which adjective best describes the following setting: "A lone cabin stood nestled amongst towering pines, smoke curling from its chimney into the crisp mountain air."
- A. Bland
 - B. Urban
 - C. Idyllic
 - D. Sterile
 
Correct answer: C
Rationale: "Idyllic" captures the peaceful and picturesque nature of the setting.
2. The gradual change in a species over time in response to environmental pressures is best described by:
- A. Punctuated equilibrium (rapid bursts of evolution)
 - B. Gradualism (slow and continuous change)
 - C. Founder effect (genetic drift in a small population)
 - D. Adaptive radiation (rapid diversification of a species)
 
Correct answer: B
Rationale: Rationale: A) Punctuated equilibrium refers to rapid bursts of evolution followed by long periods of stability, rather than gradual change over time in response to environmental pressures. B) Gradualism is the process by which species evolve through slow and continuous changes over time in response to environmental pressures. This gradual change can lead to the development of new traits and adaptations. C) Founder effect is a type of genetic drift that occurs when a small group of individuals establishes a new population, leading to a loss of genetic variation compared to the original population. It does not specifically describe the gradual change in a species over time. D) Adaptive radiation is the rapid diversification of a species into a variety of forms to exploit different ecological niches, but it does not specifically refer to the gradual change in response to environmental pressures. Therefore, the best description of the gradual change in a species over time in response to e
3. Choose the correct pronoun to complete the sentence: "Neither Michael nor Sarah ____ their homework finished yet."
- A. has
 - B. have
 - C. are having
 - D. does have
 
Correct answer: B
Rationale: When referring to "neither" followed by two subjects, the verb agrees with the plural subject ("Sarah"). So, "have" is the correct answer.
4. What is the best way to punctuate the dialogue "Are you coming?" she asked. "Maybe," I replied.
- A. "Are you coming?" she asked? "Maybe," I replied.
 - B. "Are you coming?" she asked. "Maybe," I replied.
 - C. "Are you coming?" she asked, "Maybe," I replied.
 - D. "Are you coming?" she asked, "Maybe," I replied.
 
Correct answer: B
Rationale: Each speaker's words need quotation marks, and the question mark should go inside the closing quotation mark of the question.
5. What is the scientific unit used to measure the radioactivity of a substance?
- A. Becquerel (Bq)
 - B. Joule (J)
 - C. Newton (N)
 - D. Kelvin (K)
 
Correct answer: A
Rationale: Becquerel measures the number of nuclear decays per second in a radioactive sample.
6. Which hormone, produced by the adrenal glands, helps regulate the body's response to stress, including increasing blood pressure and suppressing the immune system?
- A. Aldosterone
 - B. Epinephrine
 - C. Cortisol
 - D. Insulin
 
Correct answer: c
Rationale: The correct answer is C: Cortisol. Cortisol is a hormone produced by the adrenal glands that plays a crucial role in the body's response to stress. It helps regulate blood pressure by increasing it to prepare the body for stressors. Additionally, cortisol suppresses the immune system to prioritize the stress response. Aldosterone, while also produced by the adrenal glands, primarily regulates electrolyte balance and blood pressure. Epinephrine, produced by the adrenal medulla, is involved in the fight-or-flight response but does not suppress the immune system like cortisol. Insulin, produced by the pancreas, regulates blood sugar levels and is not directly involved in the stress response. Therefore, Cortisol is the hormone that specifically helps regulate the body's response to stress by increasing blood pressure and suppressing the immune system.
