1. What provides the cell with the ability to move and propel?

• A. Microfilaments
• B. Microtubules
• C. Flagella
• D. Cilia

Correct answer: B

Rationale: Microtubules are the cellular structures responsible for cell movement and propulsion. Microtubules are part of the cytoskeleton and play a crucial role in various cellular processes, including cell motility and intracellular transport. While microfilaments also contribute to cell movement by enabling muscle contraction and cell shape changes, they are not primarily responsible for propelling the cell. Flagella and cilia are cellular appendages involved in cell movement, but they are composed of microtubules, making them the structures that move due to the actions of microtubules.

2. A 2,000-kg car travels at 15 m/s. For a 1,500-kg car traveling at 15 m/s to generate the same momentum, what would need to happen?

• A. It would need to accelerate to 20 m/s.
• B. It would need to add 500 kg in mass.
• C. Both A and B
• D. Either A or B

Correct answer: A

Rationale: Momentum is calculated as the product of mass and velocity. Since momentum is conserved in the absence of external forces, for the 1,500-kg car to generate the same momentum as the 2,000-kg car at 15 m/s, it would need to increase its velocity to compensate for the difference in mass. Accelerating to 20 m/s would achieve this without needing to change the mass of the car. Choice B is incorrect because adding mass is not necessary to match momentum in this scenario.

3. What is the meaning of ostracize?

• A. Praise
• B. Snub
• C. Accept
• D. Include

Correct answer: B

Rationale: The correct answer is B: 'Snub.' To ostracize someone means to intentionally exclude or ignore them. Choices A, C, and D are incorrect because ostracize has a negative connotation, opposite of 'Praise,' 'Accept,' and 'Include.' Ostracize involves rejecting or isolating someone, which contrasts with the positive actions associated with the other choices.

4. Which phrase should be moved to the end of the sentence? 'The painter decided to use the urn as his subject with flowers on the table.'

• A. as his subject
• B. with flowers on the table
• C. use the urn as his subject
• D. with the urn

Correct answer: B

Rationale: Moving 'with flowers on the table' to the end of the sentence improves the sentence flow and clarity. This placement helps to maintain a logical sequence of events, enhancing the reader's understanding. Choice A, 'as his subject,' is an integral part of the main action and should not be moved. Choice C, 'use the urn as his subject,' disrupts the verb-object relationship and makes the sentence less coherent. Choice D, 'with the urn,' lacks context and does not provide a smooth transition when placed at the end of the sentence.

5. In this passage, which of these is not mentioned as a possible sign of heat exhaustion?

• A. Dizziness
• B. Nausea
• C. Headache
• D. Drowsiness

Correct answer: D

Rationale: The passage mentions dizziness, nausea, and headache as symptoms but does not list drowsiness.
