1. Which of the following words fits best in the following sentence? ___________ the emergency room was not busy last night, the head nurse still did not let anyone end her shift early.

• A. Because
• B. Provided that
• C. As if
• D. Although

Correct answer: D

Rationale: The word 'although' is the best fit in the sentence because it indicates a contrast between the fact that the emergency room was not busy last night and the head nurse's decision not to let anyone end her shift early. 'Although' sets up a contrast by acknowledging the first part of the sentence while introducing the surprising or unexpected information that follows. Choices A, B, and C do not provide the appropriate contrast needed in this context. 'Because' implies causation, 'Provided that' implies a condition for something to happen, and 'As if' implies a comparison rather than a contrast.

2. Which chemical reaction involves the formation of a single product from two or more reactants?

• A. Synthesis reaction
• B. Combustion reaction
• C. Decomposition reaction
• D. Double displacement reaction

Correct answer: A

Rationale: A synthesis reaction involves the combination of two or more reactants to form a single product. This type of reaction is characterized by the merging of substances to create a more complex compound. In a synthesis reaction, the reactants bond together to form a new product, making it the correct choice for this scenario. Combustion reactions involve the rapid combination of oxygen with another substance, resulting in the release of energy in the form of heat and light. Decomposition reactions entail the breakdown of a compound into simpler substances, often through the application of heat or electricity. Double displacement reactions involve the exchange of ions between two compounds, leading to the formation of two new compounds.

3. Multiply 12 by 15 and express the result as a decimal:

• A. 0.0018
• B. 0.018
• C. 0.18
• D. 1.8

Correct answer: D

Rationale: To find the product of 12 and 15, you simply multiply them together. 12 multiplied by 15 equals 180. To express 180 as a decimal, you divide by 100. Therefore, the correct answer is 1.8. Choices A, B, and C are incorrect as they represent values that are not the correct result of multiplying 12 by 15 and converting it to a decimal.

4. Select the meaning of the word 'distended' in the sentence: 'Wracked by abdominal pain, the victim of food poisoning moaned and rubbed his distended belly.'

• A. concave
• B. sore
• C. swollen
• D. empty

Correct answer: C

Rationale: The correct answer is C: 'swollen.' In the context provided, 'distended' refers to the victim's belly being enlarged or bloated due to abdominal pain. This matches the description of the victim moaning and rubbing his belly, indicating discomfort from swelling. Choices A, B, and D are incorrect. 'Concave' means having an inward curve, opposite to the intended meaning. 'Sore' means experiencing pain or discomfort, which is not directly related to the physical enlargement described in the sentence. 'Empty' means containing nothing, which contrasts with the idea of the belly being visibly enlarged or bloated.

5. Which organ system is largely responsible for controlling stress?

• A. The endocrine system
• B. The digestive system
• C. The lymphatic system
• D. The respiratory system

Correct answer: A

Rationale: The endocrine system is largely responsible for controlling stress through the release of hormones such as cortisol and adrenaline. These hormones help regulate the body's response to stress by increasing heart rate, blood pressure, and energy production. The endocrine system plays a crucial role in the body's stress response and helps the body adapt to and cope with stressful situations. The digestive system (Choice B) is primarily responsible for breaking down food and absorbing nutrients, not controlling stress. The lymphatic system (Choice C) is responsible for immune function and maintaining fluid balance, not controlling stress. The respiratory system (Choice D) is responsible for the exchange of oxygen and carbon dioxide, not controlling stress.
