1. What correction should the student make to the hypothesis: Lengthening the string of the pendulum increases the time it takes the ball to make one complete period?

• A. Turn it into an 'if-then' statement.
• B. Change 'will increase' to 'increases.'
• C. Switch the order of the sentence so that the phrase about the period comes first.
• D. No corrections are needed.

Correct answer: A

Rationale: The correct answer is A. A hypothesis should be structured as an 'if-then' statement for clarity. This format helps to clearly establish the relationship between the variables and the expected outcome. In this case, the student should frame the hypothesis in a way that if a specific action is taken (lengthening the string), then a specific outcome is expected (increasing the time it takes for the ball to make one complete period). 'If-then' statements are fundamental in hypothesis construction as they clearly define the cause and effect relationship being tested. Choice B is incorrect because changing 'will increase' to 'increases' does not address the structural issue of the hypothesis. Choice C is incorrect as switching the order of the sentence does not fundamentally alter the clarity of the hypothesis. Choice D is incorrect as the hypothesis structure can be improved for better understanding and testing, making correction necessary.

2. Select a verb that correctly completes the following sentence: ____________ not worry about it.

• A. Is
• B. Do
• C. You
• D. Was

Correct answer: B

Rationale: The correct answer is 'B: Do.' In the given sentence, the imperative form is used to give a command or instruction. The imperative form of the verb 'to do' is 'do,' which is commonly used in negative commands like 'Do not worry about it.' Choices 'A: Is,' 'C: You,' and 'D: Was' do not fit grammatically or contextually in completing the sentence as they are not imperative verbs.

3. Which of the following sentences from the passage includes a fact?

• A. With a running time of 98 minutes, the pacing is quick and efficient.'
• B. You can see the toll this stalking experience has had on her every twitch of her eye and clench of her jaw.'
• C. The close-up shots feel claustrophobic like the perspective is skewed.'
• D. This is a tense thrill ride that will not disappoint fans of Joy Taylor or this genre in general.'

Correct answer: A

Rationale: The correct answer is A. The sentence 'With a running time of 98 minutes, the pacing is quick and efficient' includes a fact, which is the running time of the movie. This statement provides a concrete, verifiable detail from the passage. Choice B describes a subjective observation about the character's behavior, not a fact. Choice C expresses an opinion about the visual effect of the close-up shots, not a factual detail. Choice D offers an opinion about the movie's appeal to fans of a specific genre, rather than presenting a fact from the passage.

4. Choose the correct verb form: 'Neither of the boys ____ interested in the game.'

• A. is
• B. are
• C. were
• D. be

Correct answer: A

Rationale: The subject 'Neither' is singular, so the correct verb form to use is 'is.' In this sentence, 'boys' is part of a prepositional phrase 'of the boys' and does not affect the verb agreement. 'Are' (choice B) is plural and does not match the singular subject. 'Were' (choice C) is past tense and not suitable for the present context. 'Be' (choice D) is an infinitive form and does not agree with the subject.

5. At the peak of its trajectory, what force is acting on a ball thrown upwards?

• A. Gravity only
• B. Gravity and air resistance only
• C. Neither gravity nor air resistance
• D. All of the above

Correct answer: A

Rationale: At the peak of its trajectory, the ball momentarily stops moving upwards before it starts to fall back down. At this point, the only force acting on the ball is gravity, pulling it back towards the ground. Air resistance is negligible at the peak of the trajectory as the ball is momentarily stationary. Therefore, the correct answer is 'Gravity only.' Choices B, C, and D are incorrect. Option B is incorrect because air resistance is minimal when the ball is at its highest point and its velocity is nearly zero. Option C is incorrect as gravity is the only significant force acting on the ball at that instant. Option D is incorrect since air resistance is not a significant factor at the peak of the trajectory.
