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.

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.

Correct Answer: B

Rationale: The correct answer is B, metacarpals. The metacarpals are the bones located in the hand, making up the palm and connecting to the fingers (phalanges) and wrist bones (carpals). The fibula and ulna are located in the leg and arm respectively, while the metatarsals are found in the foot. The axial skeleton consists of bones down the center of the body, including the skull, vertebrae, and ribs, while the appendicular skeleton includes bones of the arms, legs, and their attachments to the axial skeleton.

Correct Answer: B

Rationale: In the context provided, the word 'propagated' indicates that Xavier conveyed or expressed his belief to his friends. 'Expressed' is the most suitable synonym here as it aligns with the idea of communicating a belief clearly. The other options, 'shouted,' 'persuaded,' and 'whispered,' do not capture the essence of spreading or communicating an idea, making them incorrect choices.

Correct Answer: D

Rationale: The town of Audley has implemented a water conservation plan with specific watering schedules based on addresses. The city has designated different days for watering based on the ending digits of addresses, suggesting a concern for regulating water usage throughout the week. Choosing option D as the correct answer aligns with the logical reason behind the designated watering schedule. Option A is incorrect as the distribution of addresses ending with specific numbers is not the central reason for the watering schedule. Option B is incorrect as it generalizes that all addresses ending in specific numbers consume the most water, which is not supported by the provided information. Option C is incorrect as it assumes that residents at specific addresses are the most likely to consume more water, which is not explicitly stated in the given extract.
