1. The passage describes recent hurricane seasons as the most expensive on record. Which of the following statements gives the implied reason for this increased expense?

• A. Hurricane Katrina was an extremely violent storm.
• B. Valuable buildings were destroyed in New Orleans.
• C. The Atlantic Basin is entering an active period.
• D. Destruction of barrier islands and coastal wetlands has left the mainland exposed.

Correct answer: D

Rationale: The destruction of barrier islands and coastal wetlands has left the mainland exposed, leading to increased damage and expenses from hurricanes. This implies a direct reason for the increased cost of recent hurricane seasons. The other choices do not directly address the reason for the increased expenses. Choice A talks about the intensity of Hurricane Katrina but does not explain the overall trend of increased expenses. Choice B mentions buildings being destroyed, which is a consequence rather than a reason for increased expenses. Choice C discusses an active period in the Atlantic Basin but does not connect it to the increased costs of hurricane seasons.

2. What is the basic unit of communication in the nervous system?

• A. Neuron
• B. Astrocyte
• C. Neurotransmitter
• D. Synapse

Correct answer: A

Rationale: A neuron is the basic unit of communication in the nervous system. Neurons are specialized cells responsible for transmitting information through electrical and chemical signals. Astrocytes are a type of glial cell that provide support and nourishment to neurons but do not participate in signal transmission. Neurotransmitters are chemicals that facilitate signal transmission between neurons, and synapses are the specific junctions where these signals are transmitted. Therefore, the correct answer is 'A: Neuron' as it is the primary cell involved in transmitting information in the nervous system.

3. Which of the following quantities do catalysts alter to control the rate of a chemical reaction?

• A. Substrate energy
• B. Activation energy
• C. Inhibitor energy
• D. Promoter energy

Correct answer: B

Rationale: The correct answer is B: Activation energy. Catalysts function by reducing the activation energy needed for a chemical reaction to proceed. By lowering the activation energy, catalysts facilitate the reaction without being consumed themselves. Substrate energy, inhibitors, and promoters are not directly altered by catalysts in the same way activation energy is. Substrate energy refers to the energy of the reactants, which is not altered by catalysts. Inhibitors increase the activation energy required for a reaction, while promoters enhance the effectiveness of a catalyst but do not represent a quantity altered by catalysts.

4. During the Great Emu War, which of the following events happened immediately after the conflict resumed in mid-November?

• A. Military efforts became ineffective
• B. The Australian government launched the initial assault
• C. The military withdrew
• D. Emus resorted to guerrilla tactics

Correct answer: D

Rationale: The correct answer is D. According to the extract, emus resorted to guerrilla tactics during the Great Emu War. This choice aligns with the information provided, indicating that the emus changed their tactics in response to the conflict. Choices A, B, and C are incorrect as there is no mention in the extract or historical context of military efforts becoming ineffective, the Australian government launching an initial assault, or the military withdrawing immediately after the conflict resumed in mid-November.

5. What is the name of the condition characterized by inflammation of the small intestine?

• A. Appendicitis
• B. Celiac disease
• C. Gastritis
• D. Crohn's disease

Correct answer: D

Rationale: A) Appendicitis is inflammation of the appendix, not the small intestine. B) Celiac disease is an autoimmune disorder triggered by gluten consumption that damages the small intestine, but it is not characterized by inflammation alone. C) Gastritis is inflammation of the stomach lining, not the small intestine. D) Crohn's disease is a chronic inflammatory condition that can affect any part of the gastrointestinal tract, but it commonly involves the small intestine. Symptoms of Crohn's disease include abdominal pain, diarrhea, weight loss, and fatigue.
