1. Shawna buys 5.0 gallons of paint. If she uses 2.5 gallons of it on the first day, how much does she have left?

• A. 2.0 gallons
• B. 2.5 gallons
• C. 3.0 gallons
• D. 1.5 gallons

Correct answer: B

Rationale: To find the remaining paint, subtract the amount used from the total gallons bought. 5.0 - 2.5 = 2.5 gallons. Therefore, Shawna has 2.5 gallons of paint left after using 2.5 gallons on the first day. Choices A, C, and D are incorrect because they do not accurately represent the amount of paint left after using 2.5 gallons.

2. What is molarity a measure of in a solution?

• A. Volume of the solvent
• B. Amount of solute
• C. Concentration of solute
• D. Temperature of the solution

Correct answer: C

Rationale: Molarity is a measure of the concentration of a solute in a solution. It is defined as the number of moles of solute per liter of solution. Molarity is not a measure of the volume of the solvent (choice A), the amount of solute (choice B), or the temperature of the solution (choice D). Therefore, the correct answer is the concentration of solute (choice C) as molarity specifically quantifies the solute concentration in a solution.

3. This passage is mainly about

• A. slaves in the Civil War.
• B. how slaves escaped along the Underground Railroad.
• C. Harriet Tubman's role as an abolitionist leader.
• D. Harriet Tubman's life as a slave.

Correct answer: C

Rationale: The passage is mainly about Harriet Tubman's role as an abolitionist leader. It discusses her efforts to help slaves escape to freedom through the Underground Railroad and highlights her significant impact on the abolitionist movement. The focus is on Tubman's leadership and involvement in the fight against slavery, rather than just her life as a slave or the general experience of slaves during the Civil War. Choices A, B, and D are incorrect because while the passage mentions slavery, the Civil War, and Tubman's life as a slave, the primary emphasis is on her leadership and activism in the abolitionist movement.

4. Which of the following quotes offers the best summary for the instructor's motive in sending the email to the students?

• A. By now, many of you have probably seen your grade and are a little concerned. (And if you're not concerned, you should be-at least a bit!)
• B. With each class comes a new challenge, however, and as any good instructor will tell you, sometimes the original plan has to change.
• C. The purpose of the group project is to allow students to work together and arrive at a stronger response than if each worked individually.
• D. At the beginning of the semester, I informed the class that I have a strict grading policy and that all scores will stand unquestioned.

Correct answer: B

Rationale: The correct answer is B. This quote best captures the instructor's motive in the email to adjust the original plan to better support the students. Dr. Edwards is offering alternative options, including extra credit projects and a group project, to help students improve their scores after the essay exam. These options aim to provide students with opportunities to enhance their grades and succeed in the course. Choice A focuses on students feeling concerned about their grades but does not address the instructor's motive. Choice C highlights the purpose of the group project but does not capture the instructor's motive for sending the email. Choice D emphasizes the instructor's strict grading policy but does not explain the motive behind offering alternative ways to improve scores.

5. What is 1.25 as a fraction?

• A. 1 1/4
• B. 5/4
• C. 4/5
• D. 25/20

Correct answer: B

Rationale: To convert a decimal to a fraction, we note that 1.25 can be expressed as 1 + 0.25. Since 0.25 is equivalent to 25/100 or 1/4, we add 1 whole to 1/4 to get 1 1/4, which simplifies to 5/4. Therefore, 1.25 as a fraction is 5/4. Choice A (1 1/4) is the mixed number form of 5/4. Choice C (4/5) and Choice D (25/20) are incorrect fractions that do not represent 1.25.
