1. How does the acceleration of an object change if the force acting on it is doubled?

• A. Acceleration is halved
• B. Acceleration doubles
• C. Acceleration remains unchanged
• D. Acceleration quadruples

Correct answer: B

Rationale: According to Newton's second law of motion, acceleration is directly proportional to the force acting on an object. When the force acting on an object is doubled, the acceleration of the object will also double. This relationship is described by the formula F = ma, where F is the force applied, m is the mass of the object, and a is the acceleration. Therefore, an increase in force will result in a proportional increase in acceleration. Choice A is incorrect because acceleration does not halve but doubles when force doubles. Choice C is incorrect as acceleration changes in direct proportion to force. Choice D is incorrect as acceleration does not quadruple but doubles when force doubles.

2. The author of the passage notes several distinctions between Tennyson and Malory. Which of the following is not identified as a difference between the two authors?

• A. Malory wrote in prose, while Tennyson wrote in poetry.
• B. Malory wrote during the Medieval era, while Tennyson wrote during the Victorian era.
• C. Malory was more focused on heroism and morality, while Tennyson was more focused on nature and elegy.
• D. Malory wrote stories about Gareth, Tristan, and Isolde, while Tennyson focused only on Arthur, Lancelot, and Guinevere.

Correct answer: D

Rationale: The correct answer is D. The passage doesn't specifically mention the characters Gareth, Tristan, and Isolde as being exclusive to Malory. However, it does highlight that Malory focused on Arthurian legends while Tennyson also wrote about the same characters. Choice A is incorrect because Malory wrote in prose, while Tennyson wrote in poetry, as stated in the passage. Choice B is incorrect as Malory wrote during the Medieval era, while Tennyson wrote during the Victorian era, according to the passage. Choice C is incorrect because Malory was more focused on heroism and morality, while Tennyson was more focused on nature and elegy, as mentioned in the extract.

3. Which of the following is an example of a correctly punctuated sentence?

• A. Beatrice is very intelligent; however, she just does not apply herself well enough in her classes to make good grades.
• B. Beatrice is very intelligent: she just does not apply herself well enough in her classes to make good grades.
• C. Beatrice is very intelligent; she just does not apply herself well enough in her classes to make good grades.
• D. Beatrice is very intelligent; she just does not apply herself well enough in her classes to make good grades.

Correct answer: D

Rationale: Option D is the correct answer as it uses a semicolon to correctly separate two independent clauses. In this sentence, 'Beatrice is very intelligent' and 'she just does not apply herself well enough in her classes to make good grades' are two independent clauses that are related but can stand alone as separate sentences. The semicolon is the appropriate punctuation mark to link these two closely related ideas. Choices A, B, and C are incorrect because they either use a comma splice (A), a colon (B), or lack appropriate punctuation (C) to separate the independent clauses.

4. What is the main factor limiting population growth in K-strategists?

• A. Predation
• B. Availability of resources
• C. Competition
• D. Disease

Correct answer: B

Rationale: K-strategists are species with a low reproductive rate that invest more resources in raising fewer offspring. These species typically live in stable environments with limited resources. The main factor limiting population growth in K-strategists is the availability of resources such as food, shelter, and space. When resources are scarce, K-strategists may struggle to find enough to support their population size, leading to reduced reproductive success and population growth. While predation, competition, and disease can also impact population growth, the primary limiting factor for K-strategists is the availability of resources.

5. A ball is rolling across the floor and comes to a stop on its own. What force caused the ball to stop?

• A. Gravitational force
• B. Normal force from the floor
• C. Air resistance
• D. None of the above

Correct answer: C

Rationale: The force that caused the ball to stop rolling across the floor is air resistance. As the ball moves through the air, air resistance acts in the opposite direction of its motion, gradually slowing it down until it comes to a stop. In this scenario, the ball is not in contact with the floor, so the normal force from the floor does not play a role in stopping the ball. Gravitational force acts to pull objects towards the center of the Earth and would not directly stop the ball in this situation. Therefore, air resistance is the force that opposes the motion of the rolling ball and causes it to come to a stop.
