1. Which of the following is true of hypotheses of the form 'All x are y'?

A. Something that is neither x nor y disproves the hypothesis.
B. Something that is both x and y disproves the hypothesis.
C. Something that is x but not y disproves the hypothesis.
D. Something that is y but not x disproves the hypothesis.

Correct answer: D

Rationale: In hypotheses of the form 'All x are y,' the hypothesis is making a claim that all instances of x also fall under y. Therefore, if something is y but not x, it disproves the hypothesis because it contradicts the assertion that all x are y. Choice A is incorrect because something that is neither x nor y doesn't provide evidence against the hypothesis. Choice B is incorrect because if something is both x and y, it actually supports the hypothesis. Choice C is incorrect as something that is x but not y doesn't disprove the hypothesis, as it could still be consistent with the claim that all x are y.

2. Why did Julia not return to work after the alarm?

A. She was embarrassed that she could not finish the work her boss asked for.
B. She was tired and wanted to go home.
C. She got stuck in traffic and could not get back to her office.
D. Her boss gave her the afternoon off.

Correct answer: C

Rationale: The most likely reason Julia did not return to work after the alarm is that she got stuck in traffic and could not get back to her office. The extract provides details about Julia's challenging morning, starting from being woken up early by lawn mowers, having a caffeine-free cup of coffee, facing traffic delays, arriving late at work, and receiving additional work from her boss. These events culminated in Julia deciding to leave after the fire alarm, indicating that being stuck in traffic was the primary reason for her absence. Choices A, B, and D are incorrect because there is no direct evidence in the provided extract to support them. Julia's actions suggest that her decision to leave was more related to external factors like traffic issues rather than internal feelings of embarrassment, tiredness, or being given time off by her boss.

3. Which of the following could accurately subtitle this passage?

A. The start of the revolution
B. American march from the sea
C. The full armies face off
D. In the state of Massachusetts

Correct answer: A

Rationale: The passage outlines significant events in Clara Barton's life, starting from her birth in Massachusetts, moving to Washington D.C., her humanitarian work during the Civil War, and her later efforts in Europe and with the Red Cross. The most accurate subtitle for this passage would be 'The start of the revolution,' as it refers to the beginning and progression of Barton's revolutionary work in humanitarian aid and establishing the American branch of the International Red Cross Organization. The other choices are not suitable subtitles as they do not encompass the breadth of Barton's impactful life events described in the passage.

4. Given the style of writing for the passage, which of the following magazines would be the best fit for this article?

A. Scientific Spelunking
B. Family Fun Days
C. Adventures for Men
D. Mud Magazine

Correct answer: B

Rationale: The article's style is light-hearted and aimed at families looking for outdoor adventures. It suggests activities suitable for families with children, making Family Fun Days the best fit among the given magazine options. 'Scientific Spelunking' may focus more on the scientific aspects rather than family-friendly fun. 'Adventures for Men' may cater to a male audience rather than families. 'Mud Magazine' seems more focused on mud-related content, which doesn't align with the family-friendly, outdoor adventure theme of the article.

5. What text feature does the author use to organize the passage?

A. headings and subheadings
B. superscripts
C. diagrams
D. labels and footnotes

Correct answer: A

Rationale: Headings and subheadings are commonly used text features that help organize a passage by signaling different sections or topics. In this case, the passage is organized with clear headings such as 'Dairy: Beverage,' 'Dairy: Meals,' 'Dairy: Snack,' and 'Dairy: Dessert.' These headings provide a structured layout, making it easier for readers to identify specific information within each category. Superscripts, diagrams, and labels and footnotes are not used in this passage for organizing content, making them incorrect choices.
