1. What is the central idea of this passage?

A. It introduces certain insects that transition from water to air.
B. It describes how insects adapt to their environment.
C. It discusses the significance of insects in ecosystems.
D. It highlights the duality of insect life.

Correct answer: C

Rationale: The central idea of the passage is to highlight the significance of understanding insects in ecosystems, not just focusing on their adaptability or life transitions. Choice A is incorrect as the passage does not introduce specific insects transitioning from water to air. Choice B is incorrect as the main focus is not solely on how insects adapt to their environment, but on their broader role in ecosystems. Choice D is incorrect as the passage does not discuss the duality of insect life, but rather their importance in the ecosystem.

2. Which of the statements reflect information that one could reasonably infer based on the author's tone?

A. The author's tone is persuasive and aims to call the audience to action.
B. The author's tone is passionate due to excitement over the subject and personal narrative.
C. The author's tone is informative and exhibits interest in the subject of the study.
D. The author's tone is somber, depicting some anger at the state of insect larvae.

Correct answer: C

Rationale: Based on the author's tone in the excerpt, one can infer that the author's tone is informative. The author aims to educate the reader about the unique characteristics of insects, their habitats, and their life cycle. The tone is objective and descriptive, focusing on providing factual information rather than persuading or expressing passion or somberness. Choices A, B, and D are incorrect because there is no evident attempt to persuade, show excitement, or express anger in the text. Instead, the author's primary focus is on providing detailed information about the topic.

3. Based on the information provided, what is the most logical reason for the watering schedule having the same number for both Friday and Saturday?

A. There are more addresses ending with these numbers than with the other numbers.
B. All 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: C

Rationale: The most logical reason for the watering schedule having the same number for both Friday and Saturday is that the residents at addresses ending with these numbers are the most likely to consume more water. This indicates a trend in water consumption among residents at these specific addresses, leading to the need for consistent watering on both days. Choice A is incorrect as the number of addresses ending with specific numbers does not necessarily correlate with water consumption. Choice B is incorrect as there is no information suggesting that businesses consuming the most water have addresses ending with these numbers. Choice D is incorrect as there is no evidence to support that the city is more concerned about water usage specifically in the latter part of the week.

4. What is one point on which the scientist and politician agree?

A. Burning fossil fuels causes global temperatures to rise.
B. Global temperatures are increasing.
C. Countries must revisit their energy policies before it's too late.
D. Earth's climate naturally goes through warming and cooling periods.

Correct answer: B

Rationale: The correct answer is B: 'Global temperatures are increasing.' The scientist and politician both agree on this point based on the context provided. Choice A is incorrect because while it might be a common belief among scientists, the politician's agreement is not explicitly mentioned. Choice C is incorrect as it suggests a course of action rather than a point of agreement. Choice D is incorrect as it contradicts the consensus that global temperatures are currently increasing due to human activities, not just natural climate cycles.

5. How does the author distinguish between different groups of insects mentioned in the passage?

A. By describing the specific characteristics and adaptations of each insect group.
B. By grouping them based on their habitat into aquatic and aerial categories.
C. By explaining the stages of development each insect undergoes.
D. By identifying their habitats and the environments they are adapted to.

Correct answer: B

Rationale: The author distinguishes between different groups of insects based on their habitat, categorizing them into aquatic and aerial categories. The passage mentions how some insects spend time under water while others live in the air, emphasizing the distinction between aquatic and aerial habitats. Therefore, choice B is correct. Choices A, C, and D are incorrect because the passage does not focus on describing the specific characteristics, adaptations, stages of development, or environments of the insects, but rather on their habitat and lifestyle.
