1. Which of the following is an incomplete sentence?

• A. Watch out.
• B. In the rose garden out back.
• C. I guess that's true.
• D. It would take about three weeks.

Correct answer: B

Rationale: The correct answer is B: 'In the rose garden out back.' This is an incomplete sentence because it lacks a subject and a verb. A complete sentence requires both a subject (who or what the sentence is about) and a verb (action or state of being). Choices A, C, and D are complete sentences as they have the necessary components to form a grammatically correct sentence. 'Watch out' has an implied subject (you) and verb (watch), 'I guess that's true' has the subject 'I' and the verb 'guess', and 'It would take about three weeks' has the subject 'It' and the verb phrase 'would take.'

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. What is the relationship between force and acceleration according to Newton's second law?

• A. Force is directly proportional to acceleration
• B. Force is inversely proportional to acceleration
• C. Force has no relation to acceleration
• D. Force causes deceleration, not acceleration

Correct answer: A

Rationale: According to Newton's second law of motion, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This relationship is mathematically expressed as F = ma, where F represents force, m represents mass, and a represents acceleration. Therefore, an increase in force will result in a proportional increase in acceleration, supporting the statement that force is directly proportional to acceleration. Choice B is incorrect as it suggests an inverse relationship, which is not consistent with Newton's second law. Choice C is incorrect because force and acceleration are indeed related as per Newton's second law. Choice D is incorrect as force can cause acceleration or deceleration depending on the direction of the force relative to the motion of the object, but it does not exclusively cause deceleration.

4. What are the microscopic units responsible for muscle contraction called?

• A. Neurons
• B. Myofibrils
• C. Tendons
• D. Sarcomeres

Correct answer: D

Rationale: Sarcomeres are the fundamental contractile units of skeletal muscles and are responsible for muscle contraction. They consist of actin and myosin filaments that slide past each other during muscle contraction. Neurons are responsible for transmitting signals to and from muscles but are not directly involved in muscle contraction. Myofibrils are composed of sarcomeres and are the structures within muscle cells where muscle contractions take place. Tendons are connective tissues that attach muscles to bones and are not directly involved in muscle contraction.

5. In physics, what does the term 'net force' refer to?

• A. Total force acting on an object
• B. Force due to gravity
• C. Force in motion
• D. Force of friction

Correct answer: A

Rationale: In physics, the term 'net force' refers to the total force acting on an object, considering all individual forces acting on it. It is crucial in determining the object's motion and acceleration as it represents the overall force applied to the object. Choice B, 'Force due to gravity,' is incorrect as it refers to a specific force acting on an object due to gravity. Choice C, 'Force in motion,' is incorrect as it does not define the concept of net force. Choice D, 'Force of friction,' is incorrect as it specifically refers to the force opposing motion when two surfaces are in contact.
