1. Joshua needs more than 92 points to qualify for a scholarship. Each question is worth 4 points, and there are 30 questions. What inequality determines how many questions he must answer correctly?

• A. 4x < 92
• B. 4x > 92
• C. 4x < 120
• D. 4x > 120

Correct answer: B

Rationale: To determine the number of questions Joshua must answer correctly, we divide the total points required (92) by the points per question (4) to get 23. Since he needs more than 92 points, he must answer more than 23 questions correctly, which is represented by the inequality 4x > 92. Choices A, C, and D are incorrect because they do not accurately reflect the requirement for Joshua to answer more than 92 points' worth of questions.

2. How can bacteria acquire new genetic material from their environment?

• A. Transformation
• B. Transduction
• C. Conjugation
• D. All of the above

Correct answer: D

Rationale: A) Transformation: Transformation is the process by which bacteria can take up free DNA from their environment and incorporate it into their own genome, leading to the acquisition of new genetic material and traits. B) Transduction: Transduction involves the transfer of genetic material from one bacterium to another by a bacteriophage, a virus that infects bacteria. The bacteriophage carries bacterial DNA from one host cell to another, facilitating the transfer of genetic material. C) Conjugation: Conjugation is a mechanism of horizontal gene transfer in bacteria where genetic material is transferred between two bacterial cells in direct contact. This transfer is facilitated by a conjugative plasmid carrying the genetic information. Therefore, all the processes mentioned (transformation, transduction, and conjugation) are ways in which bacteria can acquire new genetic material from their environment.

3. 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.

4. Identify the conjunction in the following sentence:

• A. went
• B. to
• C. but
• D. they

Correct answer: C

Rationale: The correct answer is 'C: but.' Conjunctions are words that connect words, phrases, or clauses. In the sentence 'He went to the store, but they were already closed,' 'but' is a conjunction that joins two contrasting ideas - him going to the store and finding it closed. Choice 'A: went' is a verb, not a conjunction. Choice 'B: to' is a preposition, not a conjunction. Choice 'D: they' is a pronoun, not a conjunction.

5. The style of this passage is most like that found in a(n)

• A. tourist guidebook
• B. health textbook
• C. encyclopedia
• D. friendly letter

Correct answer: B

Rationale: The style of the given passage is most similar to that found in a health textbook. The author presents facts and details in a structured bulleted list format, focusing on providing tips and information about eating calcium-rich foods. This style is commonly used in educational materials related to health and nutrition, making choice B the most appropriate among the options provided. Choice A, a tourist guidebook, is incorrect as the passage does not aim to guide or provide information about touristic locations. Choice C, an encyclopedia, is also incorrect as an encyclopedia typically provides comprehensive and in-depth information on various topics, which is not reflected in the passage. Choice D, a friendly letter, is incorrect as the passage does not contain personal or conversational elements that are characteristic of a friendly letter.
