1. Which of the following is NOT a major function of the respiratory system in humans?

• A. It provides a large surface area for gas exchange of oxygen and carbon dioxide.
• B. It helps regulate the blood's pH.
• C. It helps cushion the heart against jarring motions.
• D. It is responsible for vocalization.

Correct answer: C

Rationale: Option C, 'It helps cushion the heart against jarring motions,' is NOT a major function of the respiratory system in humans. The primary functions of the respiratory system include gas exchange, regulation of blood pH, and vocalization. The respiratory system does not play a role in cushioning the heart; that function is primarily carried out by the pericardium and other protective structures around the heart. Choices A, B, and D are major functions of the respiratory system in humans. Choice A refers to the respiratory system's role in gas exchange, Choice B highlights its involvement in regulating blood pH, and Choice D points out its responsibility for vocalization.

2. Which of the following nucleobases does not exist in RNA?

• A. Uracil
• B. Thymine
• C. Cytosine
• D. Guanine

Correct answer: B

Rationale: The correct answer is 'B: Thymine'. Thymine is a nucleobase found in DNA but is replaced by uracil in RNA. RNA contains Uracil, Cytosine, and Guanine as its nucleobases. Cytosine and Guanine are present in both DNA and RNA, while Thymine is exclusive to DNA and Uracil is specific to RNA.

3. A dry cleaner charges $3 per shirt, $6 per pair of pants, and an extra $5 per item for mending. Annie drops off 5 shirts and 4 pairs of pants, 2 of which need mending. Assuming the cleaner charges an 8% sales tax, what will be the amount of Annie’s total bill?

• A. $45.08
• B. $49.00
• C. $52.92
• D. $88.20

Correct answer: C

Rationale: To determine the total cost before tax, calculate: 5 shirts × $3/shirt + 4 pants × $6/pair of pants + 2 items mended × $5/item mended = $49. Now, multiply this amount by 1.08 to include the 8% sales tax: $49 × 1.08 = $52.92. Therefore, Annie's total bill will be $52.92. Choice A, $45.08, is incorrect as it does not include the correct calculation for the total bill. Choice B, $49.00, is wrong because it is the total cost before tax and does not consider the added sales tax. Choice D, $88.20, is incorrect as it does not accurately calculate the total bill including the sales tax.

4. Which option best describes the use of the spider in the poem?

• A. Idiom
• B. Haiku
• C. ABBA rhyming convention
• D. Simile

Correct answer: D

Rationale: The correct answer is D, 'Simile.' In the poem, the speaker compares the spider to an artist using 'as,' indicating a simile. A simile is a figure of speech that compares two different things using 'like' or 'as.' Choices A, B, and C are incorrect. An idiom is a phrase with a figurative meaning different from its literal meaning, a haiku is a form of Japanese poetry, and ABBA rhyming convention refers to a specific rhyme scheme commonly found in poetry, none of which apply to the comparison of the spider to an artist in the poem.

5. Which word is misspelled?

• A. accommodate
• B. acquiesce
• C. circumstance
• D. indelible

Correct answer: C

Rationale: The correct answer is C. The word 'circumstance' is misspelled in the given choices. 'Accommodate,' 'acquiesce,' and 'indelible' are spelled correctly. It is important to pay attention to the spelling of words to ensure clear and accurate communication. 'Circumstance' is a common word, but in this context, it is intentionally misspelled to test your attention to detail.
