1. Select a verb that correctly completes the following sentence: ____________ not worry about it.

• A. Is
• B. Do
• C. You
• D. Was

Correct answer: B

Rationale: The correct answer is 'B: Do.' In the given sentence, the imperative form is used to give a command or instruction. The imperative form of the verb 'to do' is 'do,' which is commonly used in negative commands like 'Do not worry about it.' Choices 'A: Is,' 'C: You,' and 'D: Was' do not fit grammatically or contextually in completing the sentence as they are not imperative verbs.

2. What is the law of conservation of energy?

• A. Energy cannot be created, only destroyed
• B. Energy can be created but not destroyed
• C. Energy can neither be created nor destroyed, only transformed from one form to another
• D. Energy is always created in any process

Correct answer: C

Rationale: The correct answer is C: 'Energy can neither be created nor destroyed, only transformed from one form to another.' The law of conservation of energy is a fundamental principle in physics. It states that the total energy in a closed system remains constant over time. Energy can change from one form to another (e.g., potential energy to kinetic energy), but the total amount of energy remains the same. Choices A, B, and D are incorrect because they do not accurately represent the law of conservation of energy. Energy is not created or destroyed according to this law, but rather transformed.

3. What is the name for the change in enthalpy (heat) associated with a chemical reaction at constant pressure?

• A. Entropy
• B. Enthalpy
• C. Gibbs free energy
• D. Heat of reaction

Correct answer: D

Rationale: The correct answer is D, Heat of reaction. The heat of reaction, also known as the enthalpy change, is the amount of heat absorbed or released during a chemical reaction at constant pressure. Entropy (A) is a measure of the disorder or randomness of a system and is not specifically related to heat changes in a chemical reaction. Enthalpy (B) is the total heat content of a system and not just the change associated with a reaction. Gibbs free energy (C) is a measure of the energy available to do work in a system at constant temperature and pressure, but it is not the specific term for the heat change in a chemical reaction.

4. Based on the information in the announcement, what might the reader assume about how the university determined the lunch schedule?

• A. The university arranged the schedule alphabetically, according to the name of each department.
• B. The university checked with the departments in advance to make sure faculty members would be amenable to the change.
• C. The university checked to see when the most faculty members from each department would be entering the canteen.
• D. The university was more concerned about crowding in the canteen and simply decided to establish different times for each department.

Correct answer: C

Rationale: The announcement states that the university polled the various departments about schedules to determine a recommended roster for each department to visit the canteen for lunch. This indicates that the university checked to see when the most faculty members from each department would be entering the canteen to offset the crowding issue. Therefore, the correct choice is C. Choices A, B, and D are incorrect because there is no mention of arranging the schedule alphabetically, checking with departments in advance for agreement, or simply establishing different times without considering faculty members' schedules in the announcement. The university's approach was to tailor the lunch schedule based on each department's peak entry times to manage the crowding problem effectively.

5. Which deadly disease was eliminated through an intensive vaccination program?

• A. AIDS
• B. Smallpox
• C. Diabetes type 1
• D. Rheumatoid arthritis

Correct answer: B

Rationale: Smallpox was eradicated globally through an intensive vaccination program. The World Health Organization (WHO) led a successful global campaign to vaccinate people against smallpox, ultimately leading to its eradication in 1980. AIDS, diabetes type 1, and rheumatoid arthritis are serious conditions, but they were not eliminated through vaccination programs like smallpox. Therefore, the correct answer is B, Smallpox. AIDS is caused by the human immunodeficiency virus (HIV) and remains a significant global health issue. Diabetes type 1 is an autoimmune condition where the body attacks insulin-producing cells, leading to high blood sugar levels. Rheumatoid arthritis is an autoimmune condition that primarily affects the joints, causing inflammation and pain.
