ACCUPLACER Next Generation Reading Version 9 Questions

Explanation

<h2>Change 'show' to 'shows'</h2> The verb "show" must agree in number with its subject, which in this case is "a recent poll," a singular noun. Therefore, the correct form should be "shows" to ensure proper subject-verb agreement. <b>A) Change 'gotten' to 'got'</b> Changing "gotten" to "got" does not address the grammatical error in the sentence. The use of "gotten" is appropriate in American English, particularly in this context, and does not affect the grammatical correctness of the subject-verb agreement. <b>B) Change 'show' to 'shows'</b> This change corrects the sentence by ensuring that the singular subject "a recent poll" agrees with the verb "shows." This is the necessary adjustment to achieve grammatical correctness in the sentence. <b>C) Change 'support' to 'supported'</b> Altering "support" to "supported" incorrectly changes the tense of the verb and does not resolve the grammatical issue present in the original sentence. The original tense is appropriate as it reflects current support from the residents. <b>D) Change 'lanes' to 'lane'</b> Changing "lanes" to "lane" would alter the meaning of the sentence without addressing the grammatical mistake. The original reference to "bike lanes" indicates that multiple lanes are being supported by the residents, which is likely accurate. <b>Conclusion</b> To ensure grammatical correctness, the sentence must have the verb form match the subject. The necessary change is to alter "show" to "shows," reflecting the singular subject of the poll. The other options either do not address the grammatical issue or change the meaning unnecessarily, confirming that option B is the correct choice.

Explanation

<h2>In a study conducted by researchers.</h2> This option provides a complete and clear phrase that specifies who conducted the study, enhancing clarity and grammatical structure within the sentence. <b>A) In a study conducted by researchers</b> This choice is the best option as it clearly indicates who performed the study, providing necessary context. The phrase is grammatically correct and maintains a formal tone appropriate for academic writing. <b>B) A study conducted</b> While this choice is grammatically correct, it is incomplete as it lacks a subject to specify who conducted the study. The absence of this information diminishes clarity and leaves the reader wondering about the researchers involved. <b>C) Study conducted by the researchers</b> This option is less effective due to its omission of an article at the beginning, making it sound abrupt and incomplete. Additionally, it lacks the introductory phrase that would enhance readability and flow in the sentence. <b>D) The study which was conducted by researchers</b> This choice is unnecessarily wordy and uses "which was" in a way that complicates the sentence structure. The phrase could be streamlined for better clarity and conciseness, which is essential in effective writing. <b>Conclusion</b> The best choice is option A, as it provides a complete and clear description of the study while maintaining grammatical accuracy. Clear identification of the researchers improves the reader's understanding and enhances the overall quality of the writing. The other options either lack clarity, are incomplete, or are unnecessarily verbose, making them less suitable for the intended context.

Explanation

<h2>Change 'view' to 'viewed'</h2> The sentence describes a past action or perception regarding waking in the middle of the night, thus requiring the past tense form "viewed" to enhance clarity and grammatical correctness. <b>A) Change 'view' to 'viewed'</b> This option correctly converts the verb "view" to its past tense form "viewed," aligning the verb tense with the overall past context of the sentence. This adjustment improves clarity, indicating that this perception was held in the past rather than in the present. <b>B) Change 'as natural, useful, and even enjoyable' to 'natural, useful, and enjoyable'</b> This option eliminates the introductory phrase "as," but it does not address the verb tense issue present in the sentence. While it simplifies the list, it fails to resolve the grammatical inconsistency between "appear" and "view." <b>C) Change 'have welcomed' to 'had welcomed'</b> Changing "have welcomed" to "had welcomed" shifts the tense but does not resolve the primary issue of the verb "view." The sentence still lacks proper alignment in terms of when the perception was formed, leading to potential confusion. <b>D) Change 'appear' to 'appeared'</b> This option correctly changes "appear" to "appeared," but similar to the previous choices, it fails to address the tense of "view." While it improves the verb's alignment with the past, it does not fully clarify the sentence's meaning as effectively as option A does. <b>Conclusion</b> To enhance the clarity and grammar of the sentence, changing "view" to "viewed" is the most effective choice. This adjustment ensures that the verb tense is consistent throughout the sentence, improving readability and comprehension while maintaining the intended meaning that people historically regarded waking in the night positively.

Explanation

<h2>They may result from enforcing an unnatural sleep rhythm.</h2> Research indicates that sleep disorders can be attributed to disruptions in natural sleep patterns, often exacerbated by societal demands and lifestyles that impose rigid sleeping schedules. This unnatural rhythm interferes with the body's circadian rhythms, leading to various sleep-related issues. <b>A) They are caused by modern technology</b> While modern technology can contribute to sleep disturbances, particularly through blue light exposure and constant connectivity, it does not directly account for the broader implications of enforced sleep rhythms. The statement oversimplifies the issue by attributing sleep disorders solely to technology without considering other critical factors, such as societal expectations and lifestyle choices. <b>B) They may result from enforcing an unnatural sleep rhythm</b> This choice accurately reflects the research findings, which suggest that imposed sleep schedules disrupt natural biological rhythms. Such enforcement can lead to sleep disorders as individuals struggle to adapt to sleep patterns that do not align with their innate biological clocks, ultimately resulting in poor sleep quality and health issues. <b>C) They are linked to stress from city life</b> Although stress from urban living can influence sleep quality, this option does not encompass the central finding regarding unnatural sleep rhythms. The relationship between city life and sleep disorders is complex and multifaceted, making this explanation less precise in addressing the specific research finding. <b>D) They are unrelated to historical sleep patterns</b> This choice contradicts the research findings, which suggest that modern sleep disorders may indeed be influenced by changes from historical sleep practices. Ignoring the connection to historical patterns overlooks essential context for understanding the evolution of sleep-related issues in contemporary society. <b>Conclusion</b> The research highlights that sleep disorders often stem from the enforcement of unnatural sleep rhythms, which disrupt the body's natural circadian processes. While various factors, including technology, stress, and historical context, play roles in sleep quality, the most accurate explanation for the findings is the impact of societal expectations on natural sleep patterns. Understanding this relationship is crucial for developing effective strategies to address sleep disorders in modern life.

Explanation

<h2>To reveal the narrator’s sense of isolation from family members other than her father.</h2> The questions in sentences 10–12 of the passage focus on the narrator's feelings of disconnection from her family, emphasizing her emotional distance from relatives apart from her father. This isolation is illustrated through her reflections and inquiries, capturing her struggle to relate to others in her family. <b>A) To reveal the narrator’s sense of isolation from family members other than her father</b> This choice accurately reflects the main purpose of the questions, which highlight the narrator's feelings of being estranged from her family, except for her father. The questions underscore her emotional landscape and the complexity of her familial relationships, centering on her solitude. <b>B) To suggest the narrator’s longing for a deeper connection with her cultural heritage</b> While the narrator may experience a desire for cultural connection, the specific intent of the questions in sentences 10–12 centers more on her isolation rather than her cultural ties. This longing is not the primary focus of the questions, making this choice incorrect. <b>C) To demonstrate the narrator’s curiosity about her father’s past</b> Although curiosity about her father’s past may be present in the text, the questions specifically do not address this aspect. Instead, they concentrate on her sense of isolation, which diverges from the theme of curiosity regarding her father's history. <b>D) To highlight the narrator’s uncertainty about her own identity</b> This option suggests a theme of self-doubt, which is not the central focus of the questions in sentences 10–12. The questions are more aligned with her feelings of isolation rather than an exploration of her identity, making this choice misleading. <b>Conclusion</b> The questions in 'The Tenth Muse' serve to illuminate the narrator's sense of isolation from her family, particularly emphasizing her emotional distance from all except her father. While themes of cultural connection and identity may be present throughout the passage, the specific intent of these questions centers on her feelings of estrangement, reinforcing the complexity of her familial relationships.
