1. When evaluating the credibility of research sources, which of the following is a valid consideration?

• A. It is credible if published in a peer-reviewed scholarly journal.
• B. It is never credible if it is a source published online.
• C. It is not necessarily more credible based on author affiliations.
• D. The number of times a source is cited does not affect its credibility.

Correct answer: A

Rationale: The correct answer is A. It is credible if published in a peer-reviewed scholarly journal because peer review ensures that the research has been evaluated by experts in the field for quality and accuracy before publication. This process enhances the credibility of the research source. Choice B is incorrect because not all online sources are unreliable; credibility depends on various factors beyond the publication medium. Choice C is incorrect because author affiliations can indeed impact credibility, but they are not the sole determinant. Choice D is incorrect as the frequency of citations can indicate the impact of a source but does not guarantee its credibility.

2. Based on the context of the passage, the reader can infer that this information is likely to appear in which of the following types of works?

• A. a scholarly paper
• B. a mystery
• C. a fictional story
• D. a biography

Correct answer: D

Rationale: The information provided in the passage about the skeleton's structure and divisions, along with specific details like the number of bones and their functions, is characteristic of content found in a biography or a reference work focusing on anatomy. Biographies often include detailed factual information about historical figures, their lives, and aspects related to them, such as physical characteristics. A scholarly paper would delve deeper into analysis and research, rather than presenting basic factual information. The content in the passage is purely informative and factual, ruling out the possibility of it being part of a mystery or fictional story, which require narrative and plot elements rather than straightforward facts.

3. Which of the answer choices best describes the appropriateness of Mara's data sample?

• A. The sample is biased because it only includes teachers who are immersed in the technology field.
• B. The sample is biased because the sample size is too small.
• C. The sample is biased because the sample size is too large.
• D. The sample is not biased and is appropriate for the study.

Correct answer: A

Rationale: The correct answer is A. Mara's data sample is biased because it only includes teachers who are immersed in the technology field, specifically those teaching a computer software course. This limits the perspectives gathered, leading to skewed results. Choice B is incorrect because the issue lies in the sample composition, not its size. Choice C is incorrect as a large sample size does not necessarily indicate bias. Choice D is incorrect as the sample's bias compromises the study's validity.

4. Which of the following evidence from the passage supports the inference that providing nap rooms at work can improve employee productivity?

• A. In the recent company-wide audits, many employees have reported fatigue at work.
• B. According to a 2008 study, napping for 60 minutes helped improve verbal memory, motor skills, and perceptual learning better than caffeine.
• C. Many successful companies have adopted the practice of work naps, in industries like tech, manufacturing - even NASA!
• D. Starting today, we will be providing a designated nap room in each office building near the gym and cafeteria to help employees take care of their bodies and minds, so they can be happier, healthier, and more productive.

Correct answer: B

Rationale: The correct answer is B because the evidence from the 2008 study mentioned in the passage supports the inference that napping for 60 minutes can improve verbal memory, motor skills, and perceptual learning better than caffeine. This indicates that providing nap rooms at work can lead to improved productivity by enhancing cognitive functions. Choice A talks about the fatigue reported by employees but does not directly link it to productivity improvement. Choice C mentions that many successful companies have adopted the practice of work naps but does not specifically tie it to productivity enhancement. Choice D states the intention to provide nap rooms for employees but does not provide direct evidence of productivity improvement.

5. Why does the author repeat the phrase 'I had a dream' throughout the text?

• A. To emphasize the speaker's excitement
• B. To persuade the audience
• C. To demonstrate the speaker's authority
• D. To create a rhythmic effect

Correct answer: A

Rationale: The repetition of 'I had a dream' in the text serves to emphasize the speaker's excitement and vision. By repeating this phrase, the author highlights the importance and impact of the dream, reinforcing the central theme of hope and aspiration. Choices B, C, and D are incorrect because the primary purpose of the repetition is not persuasion, demonstration of authority, or creating a rhythmic effect, but rather to underscore the speaker's emotions and aspirations.
