1. Solve for x: 2x - 7 = 9.

• A. x = 10
• B. x = 7
• C. x = 8
• D. x = 5

Correct answer: C

Rationale: To solve the equation 2x - 7 = 9, first, add 7 to both sides to isolate the variable: 2x = 16. Then, divide by 2 to solve for x: x = 8. Choice A (x = 10) is incorrect because the solution is x = 8, not 10. Choice B (x = 7) is incorrect as it does not correctly solve the equation. Choice D (x = 5) is incorrect as it does not yield the correct solution for x.

2. Viscosity, μ, is a transport property of a fluid that reflects its:

• A. Inertia
• B. Resistance to flow
• C. Compressibility
• D. Buoyancy generation

Correct answer: B

Rationale: Viscosity refers to a fluid's resistance to flow. A fluid with high viscosity (like honey) flows slowly, while a fluid with low viscosity (like water) flows more easily. It is a measure of internal friction in the fluid. Choice A, 'Inertia,' is incorrect as inertia is the tendency of an object to resist changes in its state of motion. Choice C, 'Compressibility,' is incorrect as it refers to the ability of a fluid to be compressed. Choice D, 'Buoyancy generation,' is incorrect as it relates to the upward force exerted by a fluid that opposes the weight of an immersed object.

3. Another word for STRICT is?

• A. Stringent
• B. Daily
• C. Weekly
• D. Nominal

Correct answer: A

Rationale: The correct answer is A, "Stringent." The term "stringent" is a synonym for "strict," both denoting being rigid, precise, or exacting in rules, requirements, or standards. Choices B, C, and D are incorrect as they do not carry the same meaning as "strict." 'Daily' and 'weekly' refer to frequency, while 'nominal' means minimal or insignificant, which are not synonymous with strict.

4. I am looking forward to ___________ on a vacation next month.

• A. Go
• B. Going
• C. Be going
• D. Going to go

Correct answer: B

Rationale: In this sentence, the correct form is the gerund 'going' after the preposition 'to.' The gerund form is used after prepositions to indicate an action or state. Therefore, 'Going' is the correct choice to complete the sentence. Choice A ('Go') is incorrect because it is not the gerund form required after 'to.' Choice C ('Be going') is incorrect as it is not the standard form used in this context. Choice D ('Going to go') is redundant and unnecessarily wordy.

5. Which, if any, of the following statements are true?

• A. Water boils at approximately 100°C (212°F) at standard atmospheric pressure
• B. The boiling point is the temperature at which the vapor pressure is higher than the atmospheric pressure around the water
• C. Water boils at a lower temperature in areas of lower pressure
• D. A and C are true

Correct answer: D

Rationale: Both statements A and C are true. Water indeed boils at approximately 100°C (212°F) at standard atmospheric pressure. However, water boils at a lower temperature in areas of lower pressure due to the decreased atmospheric pressure, which affects the vapor pressure and boiling point of water. Statement B is incorrect because the boiling point is the temperature at which the vapor pressure equals the external pressure (atmospheric pressure in this case), not when it is higher.
