1. What is the instructor's main purpose in writing this email to his students?

• A. To criticize students for their poor performance on the recent essay exam
• B. To motivate students to persevere despite setbacks
• C. To offer students a chance to improve their scores and avoid failing the course
• D. To acknowledge the difficulty of the essay exam for most students

Correct answer: C

Rationale: The instructor's main purpose in writing the email is to provide students with opportunities to improve their scores and avoid failing the course. The email outlines different options for extra credit projects that can help students make up for the low scores they received on the essay exam. This shows that the instructor is focused on helping students succeed rather than criticizing them (choice A), motivating them (choice B), or acknowledging the difficulty of the exam (choice D).

2. Calcitonin, a hormone that helps regulate calcium levels, is produced by the:

• A. Thyroid gland
• B. Parathyroid gland
• C. Thymus gland
• D. Adrenal gland

Correct answer: A

Rationale: Calcitonin is a hormone produced by the thyroid gland. It helps regulate calcium levels in the body by inhibiting the breakdown of bone and promoting calcium excretion by the kidneys. The parathyroid gland produces parathyroid hormone (PTH), which works in opposition to calcitonin to regulate calcium levels. The thymus gland is involved in the development of the immune system, and the adrenal gland produces hormones such as cortisol and adrenaline. Therefore, the correct answer is the thyroid gland as it specifically secretes calcitonin for calcium regulation.

3. What is 0.25 mg to mcg?

• A. 250 mcg
• B. 25 mcg
• C. 2.5 mcg
• D. 2500 mcg

Correct answer: A

Rationale: To convert milligrams (mg) to micrograms (mcg), you multiply by 1000 because 1 mg is equal to 1000 mcg. Therefore, 0.25 mg is equal to 250 mcg. Choices B, C, and D are incorrect as they do not consider the correct conversion factor.

4. What is the term for a substance that can act as both a proton donor and a proton acceptor?

• A. Acid
• B. Base
• C. Amphiprotic
• D. Neutral

Correct answer: C

Rationale: Amphiprotic substances are those that can both donate and accept protons. They possess characteristics of both acids and bases, making them capable of acting as proton donors and proton acceptors. Choices A and B represent substances that are specific to either donating or accepting protons. Choice D does not describe a substance's ability to donate or accept protons since neutrality does not inherently involve proton donation or acceptance.

5. Which organizational style is used in the following passage? 'There are several reasons why the new student café has not been as successful as expected. One factor is that prices are higher than originally advertised, so many students cannot afford to buy food and beverages there.'

• A. Cause and effect order
• B. Compare and contrast order
• C. Spatial order
• D. Time order

Correct answer: A

Rationale: The correct organizational style used in the passage is cause and effect order. It explains the reasons (causes) why the new student café has not been successful, specifically mentioning that the higher prices lead to students being unable to afford food and beverages (effect). The passage clearly establishes a relationship between a situation (high prices) and its consequences (students not able to buy), making it a classic example of cause and effect. Choice B (Compare and contrast order) is incorrect as the passage does not present a comparison or a contrast between two or more items or situations. Choice C (Spatial order) is incorrect as it refers to organizing information based on physical location or direction, which is not applicable in this context. Choice D (Time order) is also incorrect as it involves organizing information based on a sequence of events over time, which is not the primary focus of the passage.
