1. Which of the following is listed in order from least to greatest?

• A. -2 3/4, -2 7/8, -1/5, 2/5, 1/8
• B. -1/5, 1/8, 2/5, -2 3/4, -2 7/8
• C. -2 7/8, -2 3/4, -1/5, 1/8, 2/5
• D. 1/8, 2/5, -1/5, -2 7/8, -2 3/4

Correct answer: C

Rationale: To determine the order from least to greatest, we can convert all fractions and mixed numbers to decimals or use a least common denominator. Converting the fractions in Choice C to decimals, we get -2.875, -2.75, -0.2, 0.125, and 0.4 when reading from left to right. Negative integers with larger absolute values are less than negative integers with smaller absolute values. Therefore, the correct answer is Choice C. Choices A, B, and D are incorrect because they do not present the numbers in the correct order from least to greatest when converted to decimals or compared using common denominators.

2. 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 based on the department with the most faculty members.
• B. The university checked with the departments to see when the majority of faculty members would be entering the canteen.
• C. The university checked to see when the most faculty members from each department would be entering the canteen.
• D. The university established different times for each department to reduce crowding in the canteen.

Correct answer: C

Rationale: The university determined the lunch schedule by considering when the most faculty members from each department usually enter the canteen. This information is provided in the announcement where it states that the schedules were recommended based on when members of each department should visit the canteen for lunch. Choice A is incorrect because the schedule was not arranged solely based on the department with the most faculty members. Choice B is incorrect as it implies checking with departments about the majority of faculty members entering the canteen, which is not explicitly mentioned. Choice D is incorrect as it simplifies the university's decision-making process, which involved considering the timing of faculty members from different departments entering the canteen.

3. 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.

4. What is the role of the diaphragm in the respiratory system?

• A. To regulate blood pressure
• B. To contract and expand the lungs
• C. To produce red blood cells
• D. To absorb oxygen

Correct answer: B

Rationale: The correct answer is B: To contract and expand the lungs. The diaphragm plays a crucial role in the respiratory system by contracting and expanding the lungs. When it contracts, it flattens, increasing the volume of the thoracic cavity and causing air to be drawn into the lungs. Conversely, when it relaxes, it moves back up, decreasing the thoracic cavity volume and pushing air out of the lungs. This process is essential for breathing and the exchange of oxygen and carbon dioxide in the body. Choices A, C, and D are incorrect. The diaphragm is not involved in regulating blood pressure, producing red blood cells, or absorbing oxygen. Its primary function is to aid in respiration by facilitating breathing through its contraction and relaxation movements.

5. What is the electrical charge of the nucleus?

• A. A nucleus always has a positive charge.
• B. A stable nucleus has a positive charge, but a radioactive nucleus may have no charge and instead be neutral.
• C. A nucleus always has no charge and is instead neutral.
• D. A stable nucleus has no charge and is instead neutral, but a radioactive nucleus may have a charge.

Correct answer: A

Rationale: A nucleus always has a positive charge. This is because the nucleus is composed of positively charged protons, along with neutral neutrons. The positive charge of the protons is balanced by the negative charge of the surrounding electrons in an atom, resulting in an overall neutral charge for the atom as a whole. Therefore, choice A is correct as it accurately reflects the positive charge of the nucleus due to the presence of protons. Choices B, C, and D are incorrect because they do not accurately represent the fundamental composition and charge distribution within an atom's nucleus. A stable nucleus consists of positively charged protons and neutral neutrons, leading to an overall positive charge, and not a neutral charge as suggested in the incorrect choices.
