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.

How does the author generally present the information in the extract?
- A. Chronological order
- B. Comparison-contrast
- C. Cause-effect
- D. Conclusion-premises
Correct Answer: C
Rationale: The author generally presents the information in a cause-effect format. The scientist talks about the increase in carbon dioxide emissions by countries like China, India, and Brazil leading to rising global temperatures. The politician, on the other hand, argues against a causal link between carbon emissions and temperature increase, suggesting a natural rise in temperatures. The information is structured around the cause of carbon emissions and its effect on global temperatures. Choice A, chronological order, is incorrect as the information is not presented in a time sequence but rather based on cause and effect. Choice B, comparison-contrast, is not the best description as the focus is more on cause and effect rather than comparing or contrasting different elements. Choice D, conclusion-premises, is also incorrect as the information does not follow the pattern of drawing conclusions based on premises but rather discusses the relationship between carbon emissions and temperature increase.
Which of the following best describes the organization of the information in the passage?
- A. cause-effect
- B. chronological sequence
- C. problem-solution
- D. comparison-contrast
Correct Answer: B
Rationale: The passage is organized in a chronological sequence, starting from the reign of King Charles II, proceeding to his death without a legitimate heir, the ascension of his brother James II, and the events that followed with the birth of James II's son and the subsequent fleeing of the family. The passage then covers the rejection of the young James as heir, the rise of the Jacobites, and the defeat at the Battle of Culloden in 1746. Each event is presented in the order in which they occurred. The other answer choices are incorrect: cause-effect implies a relationship of events leading to each other, problem-solution focuses on identifying issues and resolving them, and comparison-contrast involves highlighting similarities and differences between subjects, none of which are the primary organizational structure of the passage.
How many people can participate in a volleyball game?
- A. 14
- B. 15
- C. half of a class
- D. an entire class
Correct Answer: D
Rationale: Based on the extract provided, a volleyball game can involve an entire class participating. The passage mentions that with just one net and one ball, an entire class can play volleyball. While the number of participants in a volleyball game can vary, the specific reference to a whole class in the passage indicates that a significant number of people can take part. Therefore, the correct answer is 'an entire class.'
Choice A, '14,' is incorrect because the passage explicitly mentions that an entire class can participate, which typically involves more than 14 individuals. Choice B, '15,' is incorrect as it does not account for the flexibility of the number of participants in a volleyball game as stated in the passage. Choice C, 'half of a class,' is incorrect as the passage clearly states that an entire class can participate, not just half.
Which of the following bones is not part of the appendicular skeleton?
- A. skull
- B. clavicle
- C. scapula
- D. pelvic bone
Correct Answer: A
Rationale: The correct answer is A, 'skull.' The skull is part of the axial skeleton, not the appendicular skeleton. The axial skeleton, which includes the skull, vertebrae, and ribs, is located down the center of the body and protects vital organs such as the brain and heart. On the other hand, the appendicular skeleton consists of bones of the arms, legs, and the bones that attach these limbs to the axial skeleton. Choices B, C, and D (clavicle, scapula, pelvic bone) are part of the appendicular skeleton as they form the bones of the limbs and girdles that connect the limbs to the axial skeleton.
The author's purpose, major ideas, supporting details, visual aids, and vocabulary are the five key elements of what type of text?
- A. Fictional texts
- B. Narratives
- C. Persuasive texts
- D. Informational texts
Correct Answer: D
Rationale: The author's purpose, major ideas, supporting details, visual aids, and vocabulary are key elements typically found in informational texts. Informational texts aim to inform and educate readers about a specific topic, which is why these elements are crucial for effectively conveying information in a clear and organized manner. Fictional texts focus more on storytelling and creativity rather than presenting facts and information, so they do not always include these specific elements. Narratives primarily focus on telling a story or recounting events, while persuasive texts aim to convince or sway the audience's opinion, so they may not always encompass all the elements mentioned in the question.
