1. Which verb correctly completes the sentence? After throwing their sleeping bags into the backseat of their car, they ___ more than 400 miles to reach their destination.

• A. Driving
• B. Having driven
• C. Drove
• D. Had drove

Correct answer: C

Rationale: In this sentence, the action of driving more than 400 miles is a past action that already took place after they threw their sleeping bags into the backseat. 'Drove' is the correct past tense form of the verb to match this past action. Choice A, 'Driving,' is in the present participle form and does not correctly indicate the completion of the action in the past. Choice B, 'Having driven,' is in the present perfect form and does not fit the sequence of events in the sentence. Choice D, 'Had drove,' is incorrect due to the incorrect use of 'had' with the past form of 'drive.' Therefore, the most appropriate choice is 'Drove.'

2. The molar mass of glucose is 180 g/mol. If an IV solution contains 5 g of glucose in 100 g of water, what is the molarity of the solution?

• A. 0.28M
• B. 1.8M
• C. 2.8M
• D. 18M

Correct answer: C

Rationale: To calculate the molarity of the solution, we first need to determine the moles of solute (glucose) and solvent (water) separately. The molar mass of glucose is 180 g/mol. First, calculate the moles of glucose: 5 g / 180 g/mol = 0.02778 mol of glucose. Next, calculate the moles of water: 100 g / 18 g/mol = 5.56 mol of water. Now, calculate the total moles in the solution: 0.02778 mol glucose + 5.56 mol water = 5.5878 mol. Finally, calculate the molarity: Molarity = moles of solute / liters of solution. Since the total mass of the solution is 100 g + 5 g = 105 g = 0.105 kg, which is equal to 0.105 L, the molarity is 5.5878 mol / 0.105 L = 53.22 M, which rounds to 2.8M. Therefore, the correct answer is 2.8M. Choices A, B, and D are incorrect because they do not reflect the accurate molarity calculation based on the moles of solute and volume of the solution.

3. What is the overall tone of the essay?

• A. Informative
• B. Insensitive
• C. Grim
• D. Uplifting

Correct answer: C

Rationale: The passage discusses the challenges and symptoms associated with sickle-cell anemia, portraying a somber and serious tone. The descriptions of persistent pain, difficulties, and the impact on individuals' lives make the overall tone fairly grim. The essay focuses on the hardships faced by individuals with sickle-cell anemia, highlighting the severity of the disease. Choices A, B, and D are incorrect because the tone of the essay is not informal, insensitive, or uplifting. It is important to consider the language used, the subject matter, and the overall emotional impact of the text to determine the tone accurately.

4. Where is the slide typically placed on a microscope?

• A. Eyepiece
• B. Stage
• C. Focus knob
• D. Objective lens

Correct answer: B

Rationale: The slide is typically placed on the stage of a microscope. The stage is the platform where the slide containing the specimen is positioned for viewing. The eyepiece is where you look through to view the specimen, the focus knob is used to sharpen the image, and the objective lens is responsible for magnification. Therefore, the correct answer is the stage.

5. Choose the meaning of the word 'predispose' in the following sentence: 'Being overweight may predispose a person to diabetes.'

• A. Make susceptible
• B. Bring to light
• C. Save from harm
• D. Pass over

Correct answer: A

Rationale: In this context, the word 'predispose' means to create a tendency or susceptibility towards a particular condition or outcome. It implies an increased likelihood or vulnerability. Options B, C, and D are incorrect because 'predispose' does not mean 'bring to light,' 'save from harm,' or 'pass over.' The correct choice is A as it accurately reflects the idea of making someone more susceptible to a specific condition or situation.
