1. Simplify the following expression: 6 + 7 × 3 - 4 × 2

• A. -42
• B. -20
• C. 23
• D. 20

Correct answer: B

Rationale: ollow the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)): Multiply: 7 × 3 = 21, and 4 × 2 = 8 Perform addition and subtraction: 6 + 21 - 8 = 19 Thus, the simplified expression equals 19.

2. At the peak of its trajectory, what force is acting on a ball thrown upwards?

• A. Gravity only
• B. Gravity and air resistance only
• C. Neither gravity nor air resistance
• D. All of the above

Correct answer: A

Rationale: At the peak of its trajectory, the ball momentarily stops moving upwards before it starts to fall back down. At this point, the only force acting on the ball is gravity, pulling it back towards the ground. Air resistance is negligible at the peak of the trajectory as the ball is momentarily stationary. Therefore, the correct answer is 'Gravity only.' Choices B, C, and D are incorrect. Option B is incorrect because air resistance is minimal when the ball is at its highest point and its velocity is nearly zero. Option C is incorrect as gravity is the only significant force acting on the ball at that instant. Option D is incorrect since air resistance is not a significant factor at the peak of the trajectory.

3. What is the range in the number of houses sold per year?

• A. 20
• B. 25
• C. 29
• D. 35

Correct answer: C

Rationale: The range in the number of houses sold per year is calculated by subtracting the minimum number of houses sold from the maximum number of houses sold. In this case, the range is 42 (maximum) - 11 (minimum) = 31, not 29 as stated in the original rationale. Therefore, choice C (29) is incorrect. Choices A (20), B (25), and D (35) are also incorrect as they do not reflect the correct range of houses sold per year, which is 31.

4. Based on the facts in the passage, what prediction could you make about the time immediately following the Louisiana Purchase?

• A. Explorers were already on their way to the region.
• B. The government aimed to increase its power.
• C. Government officials would ensure explorers were dispatched to the region.
• D. Explorers would expect compensation for their work.

Correct answer: A

Rationale: The correct answer is A. The passage mentions that explorers like Lewis and Clark were sent to the newly acquired Louisiana Territory immediately after the Louisiana Purchase. This indicates that explorers were already on their way to the region following the purchase. Choice B is incorrect as there is no direct mention of the government wanting to increase its power right after the purchase. Choice C is incorrect as the passage does not state that government officials would specifically ensure explorers were dispatched to the region. Choice D is incorrect because there is no information provided in the passage about explorers expecting payment for their work.

5. Which of the following best describes the type of writing used in the email message sent by the instructor?

• A. technical
• B. narrative
• C. persuasive
• D. expository

Correct answer: C

Rationale: The email sent by the instructor after reconsidering his grading plan for the semester is aimed at persuading the students to understand the situation and potentially take certain actions based on his decision. It is not a technical piece that focuses on explaining complex processes, nor is it primarily a narrative recounting events. It also does not strictly provide information or explain a topic (expository writing). Instead, the email's purpose is to influence the students' perspective or behavior, making it a persuasive type of writing.
