1. Which word is NOT CORRECT? The student did not recognize which backpack was hers.

• A. Backpack
• B. Student
• C. Hers
• D. Recognize

Correct answer: C

Rationale: The correct answer is 'C: Hers.' The possessive pronoun 'hers' does not require an apostrophe. The use of 'her's' with an apostrophe is grammatically incorrect. Choices A, B, and D ('Backpack,' 'Student,' and 'Recognize') are all spelled correctly and are grammatically sound in the sentence provided.

2. Solve for x: 3x + 2 = 14

• A. x = 4
• B. x = 2
• C. x = 6
• D. x = 3

Correct answer: A

Rationale: To solve the equation 3x + 2 = 14, first, subtract 2 from both sides to isolate 3x: 3x = 12. Then, divide by 3 to solve for x: x = 4. Therefore, the correct answer is A, x = 4. Choice B, x = 2, is incorrect because it does not satisfy the equation. Choice C, x = 6, is incorrect as well since it does not satisfy the equation. Choice D, x = 3, is also incorrect as it does not satisfy the given equation.

3. Psychrometrics is a branch of thermodynamics that deals with the properties of:

• A. Ideal gases.
• B. Magnetic materials.
• C. Mixtures of moist air and water vapor.
• D. Nuclear reactions.

Correct answer: C

Rationale: Psychrometrics is the study of the physical and thermodynamic properties of gas-vapor mixtures, especially mixtures of moist air and water vapor. This branch of thermodynamics focuses on the relationships between temperature, pressure, humidity, and other properties of these mixtures. Choice A, ideal gases, is incorrect because psychrometrics specifically deals with gas-vapor mixtures, not ideal gases. Choice B, magnetic materials, and Choice D, nuclear reactions, are unrelated to psychrometrics and thermodynamics, making them incorrect. Understanding psychrometrics is crucial in fields like heating, ventilation, air conditioning, and refrigeration (HVAC&R) to design systems that effectively control air quality, comfort, and temperature.

4. Add 7/8 + 9/10 + 6/5. Express the result as a mixed number.

• A. 3 & 39/40
• B. 3 & 22/23
• C. 22/23
• D. 2 & 39/40

Correct answer: A

Rationale: To add fractions, find a common denominator, which in this case is 40. Convert each fraction to have the common denominator: 7/8 = 35/40, 9/10 = 36/40, and 6/5 = 48/40. Add these fractions to get 119/40. Simplify this improper fraction to a mixed number, which is 3 & 39/40. Choice B and C are incorrect as they do not represent the sum of the fractions. Choice D is incorrect; the whole number part should be 3, not 2.

5. Which word is not spelled correctly in the context of the sentence? Unfortunately, her absences were becoming a regular occurrence.

• A. Unfortunately
• B. absences
• C. regular
• D. occurrence

Correct answer: D

Rationale: The word 'ocurrence' is spelled incorrectly. The correct spelling is 'occurrence.' In this context, 'occurrence' refers to something happening or taking place, making it the appropriate term for the sentence. Choice A, 'Unfortunately,' is spelled correctly. Choice B, 'absences,' is spelled correctly. Choice C, 'regular,' is spelled correctly. Therefore, the incorrect spelling in the sentence is 'occurrence,' making it the right answer.
