1. Solve for x: x + 5 = x - 3.

• A. x = -5
• B. x = 5
• C. x = -3
• D. x = 3

Correct answer: A

Rationale: To solve the equation x + 5 = x - 3, we aim to isolate x. By subtracting x from both sides, we get 5 = -3, which is not possible. This indicates that the equation has no solution. Therefore, the correct answer is x = -5. Choices B, C, and D are incorrect as they do not yield a valid solution when substituted back into the original equation.

2. What best describes the plot in fiction?

• A. The main sequence of events or the storyline
• B. Character development
• C. The time and place of the story
• D. The events in the story that are true

Correct answer: A

Rationale: The correct answer is A: 'The main sequence of events or the storyline.' The plot of a fiction story refers to the series of events that make up the storyline, including the rising action, climax, and resolution. It focuses on what happens in the story rather than the development of characters (choice B), the time and place setting (choice C), or events that are factually true (choice D), which are elements distinct from the plot.

3. What best describes Samuel's sample size?

• A. The sample is biased because it has firsthand experience.
• B. The sample contains too few members to draw meaningful conclusions.
• C. The sample contains too many members to make specific claims.
• D. The sample is unbiased and of appropriate size.

Correct answer: B

Rationale: Samuel's sample size of 24 students is too small to draw generalizable conclusions about a larger population. While his observations are based on firsthand experience, the sample size is inadequate to make meaningful claims about the relationship between parental involvement and academic success for all students. Choice A is incorrect because bias is not related to sample size but rather the way data is collected. Choice C is incorrect as having too many members would not hinder understanding specifics, but rather provide a more comprehensive view. Choice D is incorrect as the sample size is too small to be considered appropriately sized for making broad claims.

4. What is the function of the alveoli in the lungs?

• A. To exchange carbon dioxide for oxygen
• B. To transport air to the lungs
• C. To filter blood
• D. To produce mucus

Correct answer: A

Rationale: The corrected answer is A: 'To exchange carbon dioxide for oxygen.' The alveoli in the lungs are responsible for facilitating gas exchange, where oxygen from inhaled air diffuses into the bloodstream, and carbon dioxide from the bloodstream diffuses into the alveoli to be exhaled. This process is vital for respiration and maintaining proper oxygen levels in the body. Choices B, C, and D are incorrect. Choice B is incorrect because the alveoli are not involved in transporting air to the lungs; they are primarily responsible for gas exchange. Choice C is incorrect because the alveoli do not filter blood; their main function is gas exchange. Choice D is incorrect because alveoli do not produce mucus; mucus is produced by other specialized cells in the respiratory system.

5. What is the author’s conclusion about the house on Pine Street?

• A. The house did not have enough bedrooms.
• B. The house did not have a big enough yard.
• C. The house was not in the right neighborhood.
• D. The house was too expensive.

Correct answer: D

Rationale: The author's conclusion about the house on Pine Street is that it was too expensive. This can be inferred from the description provided in the text, where it is mentioned that although the house had enough space inside, it didn't have a big enough yard for their dogs, and the cost of the house was well above their price range. Therefore, the correct answer is D. Choices A, B, and C are incorrect as they do not align with the evidence from the text, which clearly points to the cost being the main issue with the house on Pine Street.
