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. Which event is out of sequence in the story?

A. Installing the dog run in the backyard.
B. Enrolling the dog in obedience classes.
C. The physical exam confirming the dog's health.
D. The dog's next obedience class.

Correct answer: D

Rationale: The correct answer is D because the story describes the sequence of events after adopting the dog. After bringing Robin home, the sequence includes confirming her health with a physical exam, buying supplies, installing a dog run, and then taking her to the vet. Enrolling her in obedience classes is mentioned to start the following week, making it the next logical step. Therefore, the detail about the dog's next obedience class is not out of sequence. Choices A, B, and C are all in the correct sequence according to the events described in the story.

3. Based on the information provided, what is the most logical reason for this?

A. There are more addresses ending with these numbers than with the other numbers.
B. All residences and businesses have addresses ending in these numbers, and they consume the most water.
C. The residents at these addresses are the most likely to consume more water.
D. The city is more concerned about water usage in the latter part of the week.

Correct answer: D

Rationale: The town of Audley has implemented a water conservation plan with specific watering schedules based on addresses. The city has designated different days for watering based on the ending digits of addresses, suggesting a concern for regulating water usage throughout the week. Choosing option D as the correct answer aligns with the logical reason behind the designated watering schedule. Option A is incorrect as the distribution of addresses ending with specific numbers is not the central reason for the watering schedule. Option B is incorrect as it generalizes that all addresses ending in specific numbers consume the most water, which is not supported by the provided information. Option C is incorrect as it assumes that residents at specific addresses are the most likely to consume more water, which is not explicitly stated in the given extract.

4. Which of the following events occurred most recently?

A. Helped found National Geographic Society
B. Developed a metal detector
C. Moved to Canada
D. Invented the telephone

Correct answer: D

Rationale: Alexander Graham Bell invented the telephone after founding the National Geographic Society and developing a metal detector. Therefore, inventing the telephone is the most recent event among the options provided. Moving to Canada occurred earlier than the invention of the telephone, and helping to found the National Geographic Society also happened before the invention of the telephone.

5. Which type of evidence is used in the passage?

A. emotional evidence
B. appeal to authority
C. specific evidence
D. rhetorical questioning

Correct answer: C

Rationale: The passage uses specific evidence to support its claims. It presents factual information about the impact of private tutoring on students' grades, including a comparison of GPAs between students who had different types of tutoring. This specific evidence strengthens the argument by providing concrete data and examples. Emotional evidence, appeal to authority, and rhetorical questioning are not used in this passage, as it primarily relies on data and analysis to make its case.
