1. Which of the following sources would be a good starting point that provides the most accurate information for a research project on ancient Persian culture?

• A. The Wikipedia entry on 'Persian Culture'
• B. 'All Cool Persian Stuff,' a blog written by a scientist
• C. 'An Overview of Persian Society,' a book written by a historian
• D. 'Uncovering the Secrets of Persia,' a two-page magazine article about lost temples

Correct answer: C

Rationale: A book written by a historian, such as 'An Overview of Persian Society,' would provide a well-researched and reliable source of information on ancient Persian culture. Choice A, the Wikipedia entry, may contain inaccurate or biased information as it can be edited by anyone. Choice B, a blog by a scientist, may not provide scholarly or comprehensive information on ancient Persian culture. Choice D, a magazine article about lost temples, does not focus on Persian culture as a whole, making it less relevant for a research project specifically on ancient Persian culture.

2. When evaluating the credibility of a source during research, which statement is true?

• A. The author's reputation is more important than whether they cite sources.
• B. The source should always be as recent as possible, considering the subject.
• C. The author's point of view and/or purpose is crucial for credibility.
• D. The kinds of sources various audiences value influence credibility for them.

Correct answer: D

Rationale: The kind of sources different audiences value can indeed influence the credibility of a source for them. Different audiences may place varying levels of trust in different types of sources, such as peer-reviewed journals, government reports, or mainstream media outlets. Understanding the preferences of the target audience is essential for establishing credibility when presenting information. Choices A, B, and C are incorrect. The author's reputation is important but not more critical than citing sources, as proper citations contribute to transparency and reliability. The recency of a source is essential but not always the most crucial factor; relevance to the subject matter is also significant. The author's point of view and purpose are indeed relevant to assessing credibility; understanding their biases and intentions is vital in evaluating the reliability of a source.

3. This passage is mainly about

• A. slaves in the Civil War.
• B. how slaves escaped along the Underground Railroad.
• C. Harriet Tubman's role as an abolitionist leader.
• D. Harriet Tubman's life as a slave.

Correct answer: C

Rationale: The passage is mainly about Harriet Tubman's role as an abolitionist leader. It discusses her efforts to help slaves escape to freedom through the Underground Railroad and highlights her significant impact on the abolitionist movement. The focus is on Tubman's leadership and involvement in the fight against slavery, rather than just her life as a slave or the general experience of slaves during the Civil War. Choices A, B, and D are incorrect because while the passage mentions slavery, the Civil War, and Tubman's life as a slave, the primary emphasis is on her leadership and activism in the abolitionist movement.

• A. Self-improvement classes teach work-related skills.
• B. Attendance is voluntary for self-improvement classes.
• C. Many different kinds of self-improvement classes are available.
• D. Cooking is one type of self-improvement classes.

Correct answer: C

Rationale: The central idea of the passage is that there are many different kinds of self-improvement classes available. The passage discusses various topics such as cooking, yoga, language learning, and computer skills, emphasizing the range of options for self-improvement classes. This choice captures the main theme of the passage focusing on the diversity of available classes for personal development.

5. According to the passage, what effect does encountering an automobile with eighteen wheels have on the hypothesis 'All automobiles have only four wheels'?

• A. It proves the hypothesis.
• B. It raises the hypothesis's probability.
• C. It disproves the hypothesis.
• D. It decreases the hypothesis's probability.

Correct answer: C

Rationale: Encountering an automobile with eighteen wheels contradicts the hypothesis that all automobiles have only four wheels. This contradicts the initial hypothesis, proving it to be false. The passage explains that when evidence disproves a hypothesis, it directly contradicts the hypothesis, leading to its disproof. In the context of the monkey example provided, encountering a hairless monkey out of many hairy monkeys disproved the hypothesis 'All monkeys are hairy.' Therefore, the presence of an automobile with eighteen wheels disproves the hypothesis that all automobiles have only four wheels. Other choices are incorrect because encountering such an automobile directly contradicts the initial hypothesis, leading to its disproof, rather than proving it, raising its probability, or decreasing its probability.
