1. What is the best summary of the instructor's motive in sending the email to the students?

• A. Expressing concern about students' grades and emphasizing the importance of being worried.
• B. Recognizing the low exam scores and the need to adjust the grading plan to help students improve.
• C. Explaining the purpose of a group project and how it benefits students working together.
• D. Stating the strict grading policy set at the beginning of the semester.

Correct answer: B

Rationale: Answer choice B is the correct summary of the instructor's motive in sending the email to the students. The passage mentions that the instructor acknowledged the low exam scores, including a high failure rate and the need to reconsider the grading plan for the semester. This indicates that the instructor wants to adjust the grading plan to provide students with an opportunity to improve their scores. Choice A is incorrect as it focuses on expressing concern rather than on adjusting the grading plan. Choice C is unrelated as it discusses the purpose of a group project. Choice D is also incorrect as it mentions the strict grading policy set at the beginning of the semester, which is not the main focus of the email sent by the instructor.

2. Which word is a synonym for 'brief'?

• A. Short
• B. Long
• C. Detailed
• D. Wordy

Correct answer: A

Rationale: 'Short' is the correct answer because it is a synonym for 'brief,' meaning concise or not lengthy. 'Long' (Choice B) is the opposite of 'brief.' 'Detailed' (Choice C) and 'Wordy' (Choice D) both imply a level of depth or excess information, making them incorrect choices.

3. What does the innate immune system provide?

• A. Nonspecific, immediate defense against pathogens
• B. Specific, long-term immune response through memory cells
• C. Both (a) and (b)
• D. Neither (a) nor (b)

Correct answer: A

Rationale: The correct answer is A. The innate immune system provides nonspecific, immediate defense against pathogens. It is the body's first line of defense in responding to infections and does not involve memory cells or specific long-term immune responses like the adaptive immune system. Choice B is incorrect because specific, long-term immune responses through memory cells are characteristics of the adaptive immune system, not the innate immune system. Choice C is incorrect because the innate immune system does not provide specific, long-term immune responses. Choice D is incorrect because the innate immune system does provide an immediate defense against pathogens.

4. Which of the following best describes a function carried out by the circulatory system and the integumentary system working together?

• A. Removal of excess heat from the body
• B. Hormonal regulation of blood pressure
• C. Transport of oxygen in the body
• D. Production of red blood cells in the bone marrow

Correct answer: A

Rationale: The correct answer is A: Removal of excess heat from the body. The circulatory system, which includes blood vessels and the heart, works with the integumentary system, which consists of the skin, to regulate body temperature by removing excess heat. This process involves blood vessels near the skin's surface dilating to release heat and constricting to conserve heat, a mechanism crucial for maintaining homeostasis. Option B, Hormonal regulation of blood pressure, is incorrect as it does not accurately describe the collaborative function of these systems in regulating body temperature. Option C, Transport of oxygen in the body, is incorrect as it focuses on a different function of the circulatory system. Option D, Production of red blood cells in the bone marrow, is incorrect as it pertains to the skeletal and hematopoietic systems, not the circulatory and integumentary systems working together to regulate body temperature.

5. The day was cold and wet. Jesse was worried that he would not beat his best time. Jesse had trained for the marathon for 6 months. Which of the following options uses correct grammar to combine the sentences for clarity?

• A. The day was cold and wet, and Jesse was worried that he would not beat his best time. Jesse had trained for the marathon for 6 months.
• B. Jesse was worried that he would not beat his best time because the day was cold and wet, and he had trained for the marathon for 6 months.
• C. Because Jesse had trained for the marathon for 6 months, he was worried that he would not beat his best time. The day was cold and wet.
• D. Jesse had trained for the marathon for 6 months, but because the day was cold and wet, Jesse was worried that he would not beat his best time.

Correct answer: D

Rationale: Sentence D is the correct choice as it combines the sentences logically and clearly, showing cause and effect. It effectively connects the reason for Jesse's worry (the cold and wet day) with his training for the marathon. Choice A lacks a conjunction before 'Jesse was worried,' making it less clear. Choice B changes the sequence of events and weakens the cause-effect relationship. Choice C incorrectly places the reason for worry after the effect, leading to confusion in the sentence structure.
