1. What is the length of the unknown leg of a right triangle that has one leg measuring 9 feet and a hypotenuse of 19 feet? (Round to the nearest tenth.)

• A. 16.7 feet
• B. 16.0 feet
• C. 17.4 feet
• D. 8.4 feet

Correct answer: A

Rationale: To find the length of the unknown leg (a) of a right triangle, use the Pythagorean theorem: a² + 9² = 19². Substitute the known values, solve for a: a² + 81 = 361. Subtract 81 from both sides to get a² = 280. Taking the square root of 280 gives a ≈ 16.7 feet. Therefore, the correct answer is 16.7 feet. Choice B (16.0 feet) is incorrect as it does not accurately round to the nearest tenth. Choice C (17.4 feet) and choice D (8.4 feet) are incorrect as they do not match the calculated value using the Pythagorean theorem.

2. Which of the following is not an example given by the author of an element of the Western paradigm?

• A. Hero highly skilled at warfare
• B. Evil villain in black hat
• C. Everyone riding horses
• D. Community made up of upstanding citizens

Correct answer: C

Rationale: The author did not mention everyone riding horses as an element of the Western paradigm in the provided passage. The passage discusses the virtuous hero in the white hat, the evil villain in the black hat, and the community made up of upstanding citizens as elements of the Western paradigm. The hero being highly skilled at warfare and the community having morally upstanding citizens were also mentioned. Therefore, option C is the correct answer. Options A, B, and D are incorrect because they were all examples given by the author in the passage.

3. Which indicator is commonly used to distinguish between acidic and basic solutions?

• A. Methyl orange
• B. Phenolphthalein
• C. Universal indicator
• D. All of the above are common indicators.

Correct answer: B

Rationale: Phenolphthalein is commonly used to differentiate between acidic and basic solutions. It changes color, turning pink in basic solutions and remaining colorless in acidic solutions due to a specific pH range. While methyl orange and universal indicator are also indicators used for pH testing, phenolphthalein is especially known for its distinctive color change in response to acidic and basic solutions, making it the correct choice. Methyl orange is typically used in titrations for a sharp color change at a specific pH, and the universal indicator is a mixture of indicators displaying a range of colors depending on the pH value, not specifically tailored to acidic and basic distinctions.

4. Identify the relative clause in the sentence 'The book that won the award was a bestseller.'

• A. 'The book'
• B. 'that won the award'
• C. 'was a bestseller'
• D. 'award'

Correct answer: B

Rationale: The correct answer is 'B: 'that won the award.' A relative clause provides additional information about a noun in the sentence. In this case, 'that won the award' is the relative clause specifying which book out of all books is being referred to. It is essential to recognize and understand relative clauses for better comprehension of sentence structures. Choice A ('The book') is the main noun phrase and not a relative clause. Choice C ('was a bestseller') is the main clause of the sentence, not a relative clause. Choice D ('award') is a noun but not a relative clause as it does not provide additional information about a noun in the sentence.

5. What type of chemical bond connects the oxygen and hydrogen atoms in a molecule of water?

• A. Static bond
• B. Aquatic bond
• C. Ionic bond
• D. Covalent bond

Correct answer: D

Rationale: The correct answer is D, Covalent bond. Covalent bonds are formed between oxygen and hydrogen atoms in a water molecule. In a water molecule, each hydrogen atom forms a covalent bond with the oxygen atom, sharing electrons to achieve a stable configuration. Static bond (choice A) and Aquatic bond (choice B) are not valid types of chemical bonds. Ionic bond (choice C) involves the transfer of electrons between atoms of different electronegativities, which is not the case between oxygen and hydrogen in a water molecule.
