1. Which of the following sentences uses the MOST formal language?

• A. I can’t come to your party.
• B. I will be unable to come to your party.
• C. I won't be able to go to your party.
• D. I can't go to your party.

Correct answer: B

Rationale: The correct answer is 'I will be unable to come to your party.' This sentence uses formal language by avoiding contractions and employing a more polished wording. Choice A, 'I can’t come to your party,' contains a contraction ('can’t'), which makes it less formal. Choice C, 'I won't be able to go to your party,' though polite, still uses a contraction ('won't') and is not as formal as the correct answer. Choice D, 'I can't go to your party,' also includes a contraction and is less formal compared to the most formal choice, which is option B.

2. What is the purpose of the italics used for several of the works identified in the sentence above?

• A. to indicate a full-length published book
• B. to indicate a work of classic literature
• C. to indicate recommended summer reading
• D. to indicate books that Angela completed

Correct answer: A

Rationale: The purpose of the italics used for several of the works identified in the sentence above is to indicate a full-length published book. In the provided extract, titles of books such as 'The Great Gatsby,' 'Brave New World,' 'A Passage to India,' and 'The Cask of Amontillado' are italicized to emphasize them as standalone works. This formatting convention is commonly used to highlight titles of books, magazines, movies, and other individual works in written text. Choices B, C, and D are incorrect as the italics are not specifically indicating classic literature, recommended summer reading, or completion by Angela, but rather serving the general purpose of emphasizing standalone works.

3. An object is thrown upwards and reaches a maximum height. Which of the following statements is TRUE about its velocity and acceleration at the peak?

• A. Velocity is zero and acceleration is maximum upwards.
• B. Velocity is maximum and acceleration is zero.
• C. Velocity is maximum and acceleration is maximum upwards.
• D. Velocity is zero and acceleration is maximum downwards.

Correct answer: A

Rationale: At the peak of the object's motion, its velocity is zero because it momentarily stops before changing direction and starts to fall back down. The acceleration at the peak is maximum upwards as gravity is acting against the object's motion, slowing it down until it stops momentarily. Choice A is correct because at the peak, the object's velocity is zero, and the acceleration is maximum upwards. Choice B is incorrect because the velocity is not maximum but zero at the peak. Choice C is incorrect as both velocity and acceleration are not maximum at the peak. Choice D is incorrect as the acceleration at the peak is upwards, opposing the object's motion, not downwards.

4. When evaluating the credibility of a source during research, which statement is true?

• A. The author's reputation is more important than whether they cite sources.
• B. The source should always be as recent as possible, considering the subject.
• C. The author's point of view and/or purpose is crucial for credibility.
• D. The kinds of sources various audiences value influence credibility for them.

Correct answer: D

Rationale: The kind of sources different audiences value can indeed influence the credibility of a source for them. Different audiences may place varying levels of trust in different types of sources, such as peer-reviewed journals, government reports, or mainstream media outlets. Understanding the preferences of the target audience is essential for establishing credibility when presenting information. Choices A, B, and C are incorrect. The author's reputation is important but not more critical than citing sources, as proper citations contribute to transparency and reliability. The recency of a source is essential but not always the most crucial factor; relevance to the subject matter is also significant. The author's point of view and purpose are indeed relevant to assessing credibility; understanding their biases and intentions is vital in evaluating the reliability of a source.

5. What is the work done by a force of 20 N acting on an object that moves 5 meters in the direction of the force?

• A. 100 Joules (J)
• B. 25 Joules (J)
• C. 4 Joules (J)
• D. Work cannot be determined without knowing the object's mass.

Correct answer: A

Rationale: The work done is calculated using the formula: Work = Force x Distance x cos(theta), where theta is the angle between the force and the direction of motion. In this case, the force and the direction of motion are in the same direction, so cos(theta) = 1. Therefore, Work = 20 N x 5 m x 1 = 100 Joules. Since the force and distance are given and are in the same direction, the work done can be directly calculated without needing to know the object's mass. Choice A, 100 Joules, is the correct answer as calculated. Choice B and C are incorrect as they do not correspond to the correct calculation. Choice D is incorrect because knowing the object's mass is not necessary to calculate work in this scenario, as work is dependent on force, distance, and the angle between them, not mass.
