1. Find the lowest coefficients that will balance the following combustion equation: __C H + __O2 → __CO2 + __H2O

• A. 1:5:5:2
• B. 4:10:20:8
• C. 2:9:10:4
• D. 2:5:10:4

Correct answer: C

Rationale: To balance the combustion equation CxHy + O2 → xCO2 + y/2 H2O, we need to balance the carbon and hydrogen atoms. The balanced equation for the given combustion is: 2C H4 + 9O2 → 2CO2 + 4H2O. This means that the correct coefficients are 2:9:10:4, which corresponds to choice C. Choice A (1:5:5:2) does not balance the equation correctly, choice B (4:10:20:8) has excessive oxygen and does not balance the equation, and choice D (2:5:10:4) does not provide the correct ratio of oxygen to balance the equation.

2. What is the end result of mitosis in animal cells?

• A. The production of two identical daughter cells
• B. The production of four haploid cells
• C. The production of a single diploid cell
• D. The production of a single haploid cell

Correct answer: A

Rationale: Mitosis is a type of cell division specific to eukaryotic cells that results in the production of two identical daughter cells, each with the same genetic material as the parent cell. This process is crucial for growth, tissue repair, and maintaining a constant number of chromosomes in multicellular organisms. During mitosis, the replicated chromosomes are segregated into two separate nuclei, followed by the division of the cell into two identical daughter cells. Options B, C, and D are incorrect as mitosis does not lead to the production of four haploid cells, a single diploid cell, or a single haploid cell. The correct answer is A because mitosis results in the formation of two daughter cells that are genetically identical to each other and to the parent cell, allowing for growth and replacement of damaged cells in multicellular organisms.

3. Why are italics used in the sentence, 'Although Ben said he supported his coworkers, his actions suggested he did not condone their behavior'?

• A. to show a word is intentionally misspelled
• B. to indicate a word in a foreign language
• C. to emphasize a contrast
• D. to reference a footnote

Correct answer: C

Rationale: Italics are often used in writing to draw attention to specific words or phrases, especially in cases where there is a contrast or emphasis intended. In this sentence, the use of italics on 'supported' and 'condone' helps highlight the contradiction between Ben's words and actions, emphasizing the contrast between what he said and what he actually did. Choice A is incorrect because italics are not used to indicate intentional misspellings in this context. Choice B is incorrect as italics are not used to indicate foreign words in this sentence. Choice D is incorrect as there is no mention of footnotes in the sentence.

4. Which of the following best describes the author’s purpose?

• A. The author wants to tell customers about the cars available at Carl’s Car Depot.
• B. The author wants to encourage other car dealerships to lower their prices.
• C. The author wants to provide new and used cars at affordable prices.
• D. The author wants to attract customers to Carl’s Car Depot.

Correct answer: D

Rationale: The author's purpose is to attract customers to Carl's Car Depot. The text from the extract clearly emphasizes the one-day-only summer sale event at Carl’s Car Depot, highlighting the wide range of cars available at discounted prices with special financing options. The author aims to draw in potential customers by presenting compelling offers and creating a sense of urgency. Choices A, B, and C are incorrect because the primary focus is on attracting customers to Carl’s Car Depot by showcasing the available cars and the limited-time sale, not solely informing customers about the cars, urging other dealerships to lower prices, or generally providing affordable cars.

5. Which of the following best provides detailed support for the claim that 'seatbelts save lives'?

• A. A government website containing driving accident information
• B. A blog developed by one of the largest car companies in the world
• C. An encyclopedia entry on the seatbelt and its development
• D. A social media post from a famous race car driver

Correct answer: A

Rationale: The correct answer is A. Government websites usually contain reliable and detailed statistics supporting the effectiveness of seatbelts. Choice B, a blog from a car company, may have biased information to promote their products. Choice C, an encyclopedia entry, may not necessarily have the most up-to-date or detailed information on the topic. Choice D, a social media post from a race car driver, lacks the credibility and detailed information that a government website can provide.
