1. If a theory is obsolete, what is true of it?

A. Up to date
B. Outdated
C. Innovative
D. Scientific

Correct answer: B

Rationale: The correct answer is B: 'Outdated.' When something is described as 'obsolete,' it means that it is outdated or no longer in use. Therefore, an obsolete theory is no longer current or relevant. Choices A, C, and D are incorrect because an obsolete theory is not considered up to date, innovative, or necessarily scientific; it is outdated and no longer relevant in its field.

2. What does Nebulous mean?

A. Clear
B. Vague
C. Distinct
D. Complex

Correct answer: B

Rationale: The correct answer is B: 'Vague.' Nebulous means something that is vague or unclear. Choices A, C, and D are incorrect because nebulous is the opposite of clear, distinct, and complex. Nebulous refers to something lacking definite form or limits, making it difficult to understand or perceive clearly.

3. Replete is best defined as being ___________.

A. hardy
B. quiet
C. full
D. sad

Correct answer: C

Rationale: Replete means filled to the utmost capacity or complete in every detail. Therefore, the best definition of replete from the given choices is 'full.' Choice A, 'hardy,' does not accurately reflect the meaning of replete. Choice B, 'quiet,' is unrelated to the definition of replete. Choice D, 'sad,' is also not synonymous with the term replete.

4. Which term refers to a team captain's exaggerated claim about the number of goals he or she scored during the game?

A. Hyperbole
B. Validity
C. Eulogy
D. Simile

Correct answer: A

Rationale: The correct answer is 'Hyperbole.' Hyperbole refers to exaggerated statements or claims not meant to be taken literally. In this context, the team captain's claim about the number of goals scored is an exaggerated statement, making 'Hyperbole' the most suitable term. 'Validity' refers to the quality of being logically or factually sound and does not fit the scenario described. 'Eulogy' is a speech or piece of writing that praises someone or something, typically someone who has died, and is unrelated to the question. 'Simile' is a figure of speech involving the comparison of one thing with another thing of a different kind, used to make a description more emphatic or vivid, which is not the case in the scenario provided.

5. What is a Nutrient?

A. A chemical compound
B. A substance that provides nourishment
C. A non-essential mineral
D. An essential vitamin

Correct answer: B

Rationale: A nutrient is a substance that provides nourishment to the body, such as carbohydrates, proteins, fats, vitamins, and minerals. Choice A has been improved to 'A chemical compound' to be more specific. Choice A is incorrect as it is too general and does not specifically describe the role of a nutrient. Choice C is incorrect as it focuses on minerals without specifying that all minerals are nutrients. Choice D is also incorrect as it solely emphasizes vitamins, which are just one type of nutrient.
