1. A rocket engine expels hot gases backwards. What principle explains the rocket's forward motion?

• A. Newton's first law of motion
• B. Newton's second law of motion
• C. Newton's third law of motion
• D. Law of conservation of energy

Correct answer: C

Rationale: Newton's third law of motion states that for every action, there is an equal and opposite reaction. In the case of a rocket engine expelling hot gases backwards, the action is the expulsion of gases, and the reaction is the forward motion of the rocket. The hot gases being expelled act as the action force, propelling the rocket in the opposite direction as the reaction force, resulting in the rocket's forward motion. Newton's first law of motion (Choice A) pertains to inertia, stating that an object in motion will stay in motion unless acted upon by an external force. Newton's second law of motion (Choice B) relates force, mass, and acceleration, which is not directly applicable to the scenario of a rocket engine propulsion. The law of conservation of energy (Choice D) is a fundamental principle stating that energy cannot be created or destroyed but can only be transformed, which does not directly explain the forward motion of the rocket in this context.

2. Which of the following is a risk factor for developing kidney stones?

• A. Consuming a diet rich in fruits and vegetables
• B. Maintaining adequate hydration with water
• C. Having a family history of kidney stones
• D. Regularly engaging in moderate exercise

Correct answer: C

Rationale: Having a family history of kidney stones is a risk factor for developing kidney stones. Genetic predisposition can increase the likelihood of developing kidney stones due to inherited traits that affect the body's ability to process and excrete certain substances. Consuming a diet rich in fruits and vegetables (option A) and maintaining adequate hydration with water (option B) are actually recommended strategies to help prevent kidney stones by promoting overall kidney health. Regularly engaging in moderate exercise (option D) can also be beneficial for kidney health by promoting circulation and overall well-being. Therefore, options A, B, and D are not risk factors but rather beneficial for kidney health.

3. What is the author's likely purpose in writing this passage about Queen Victoria?

• A. To persuade the reader to appreciate the accomplishments of Queen Victoria, especially when placed against the failures of her forebears.
• B. To introduce the historical impact of the Victorian Era by introducing the queen who gave that era its name.
• C. To explain how small events in history led an unlikely princess to become the queen of England.
• D. To indicate the role that King George III's many sons played in changing the history of England.

Correct answer: C

Rationale: The author's likely purpose in writing this passage about Queen Victoria is to explain how small events in history led to an unlikely princess becoming the queen of England. The passage details the series of events that changed the course of British succession and highlights Victoria's unexpected path to the throne. It focuses on the historical process that resulted in her becoming queen, rather than persuading the reader to appreciate her accomplishments, introducing the Victorian Era as a whole, or discussing the role of other historical figures like King George III's sons.

4. Which plane divides the body into superior (top) and inferior (bottom) halves?

• A. Sagittal/Median Plane
• B. Frontal/Coronal Plane
• C. Transverse/Cross-Section Plane
• D. Horizontal Plane

Correct answer: C

Rationale: The Transverse or Cross-Section Plane is the correct answer as it divides the body into superior (top) and inferior (bottom) halves. This plane runs horizontally across the body, perpendicular to the long axis, separating the body into upper and lower sections. Choice A, the Sagittal/Median Plane, divides the body into left and right halves, not superior and inferior halves. Choice B, the Frontal/Coronal Plane, divides the body into anterior (front) and posterior (back) halves. Choice D, the Horizontal Plane, is not a standard anatomical plane used to divide the body into specific sections.

5. Which of the following best describes the instructor's purpose in writing this email to his students?

• A. to berate students for the poor scores they received on the recent essay exam
• B. to encourage students to continue working hard despite failure
• C. to give students the opportunity to make up the bad score and avoid failing the course
• D. to admit that the essay exam was likely too difficult for most students

Correct answer: C

Rationale: The correct answer is C. The instructor's primary purpose in writing the email is to offer students the chance to make up the bad score they received on the recent essay exam, which was worth 70% of their final course score. The email does not berate students for their poor performance, nor does it admit that the exam was too difficult. While the instructor does offer encouragement to students who choose to complete an extra credit project, the main focus is on providing an opportunity to improve their scores and avoid failing the course.
