1. What punctuation is needed in the following sentence to make it correct? Do not be afraid to ask questions in his class, he is very approachable and explains things well.

• A. Hyphen
• B. Comma
• C. Apostrophe
• D. Semicolon

Correct answer: B

Rationale: The correct punctuation needed in the given sentence is a comma after 'class.' This comma is necessary to separate the two independent clauses 'Do not be afraid to ask questions in his class' and 'he is very approachable and explains things well.' Commas are used to separate independent clauses when they are joined by a coordinating conjunction like 'and.' Choice A, 'Hyphen,' is incorrect as a hyphen is not needed to connect any words in the sentence. Choice C, 'Apostrophe,' is incorrect as there is no possession or contraction being indicated in the sentence that requires an apostrophe. Choice D, 'Semicolon,' is incorrect as a semicolon is not used to join two independent clauses in this context; a comma followed by a coordinating conjunction is more appropriate.

2. What does 'Fatal' mean?

• A. Resulting in injury
• B. Resulting in death
• C. Dangerous
• D. Treatable

Correct answer: B

Rationale: The correct answer is B: 'Resulting in death.' The term 'Fatal' specifically means resulting in death. Choices A, C, and D are incorrect because 'Fatal' does not refer to resulting in injury, being dangerous, or being treatable.

3. Select the phrase that will make the following sentence grammatically correct. Until the semester ends, Lily ___________.

• A. is not traveling far from town
• B. has not traveled far from town
• C. will not have traveled far from town
• D. will not travel far from town

Correct answer: D

Rationale: The correct phrase should use the future tense because it indicates an action that will happen in the future. The phrase 'will not travel far from town' fits this requirement, making the sentence grammatically correct. Choices A, B, and C are incorrect as they do not express a future action, which is needed in this context.

4. If x=11, solve (x+44)/2x.

• A. 33
• B. 2.5
• C. 13
• D. 55/22

Correct answer: B

Rationale: Given x=11, substitute into the expression: (11 + 44) / (2*11) = 55 / 22 = 2.5. Therefore, the correct answer is 2.5. Choice A (33) is incorrect as it does not represent the correct calculation. Choice C (13) is incorrect as it is not the result of the expression. Choice D (55/22) is incorrect as it is the same as the simplified form of the expression, not the answer to the calculation.

5. What characterizes laminar flow?

• A. Smooth, parallel layers of fluid particles
• B. Erratic and turbulent motion of fluid particles
• C. High viscosity hindering flow
• D. Incompressibility of the fluid

Correct answer: A

Rationale: Laminar flow is characterized by the smooth, parallel movement of fluid particles along layers in a predictable manner. This flow regime occurs at low velocities and is in contrast to turbulent flow, where fluid particles exhibit erratic and chaotic motion. The viscosity of the fluid does not hinder laminar flow; instead, it influences the resistance to flow. Incompressibility is a property of fluids but does not specifically define laminar flow. Therefore, the correct answer is A as it accurately describes the behavior of fluid particles in laminar flow, making B, C, and D incorrect.
