1. What is the librarian's best course of action in this situation?

• A. The librarian shows the student how to do an Internet search using Google
• B. Since the assignment is to read a biography, the librarian directs the student to the biography section of the library rather than to the Internet. She helps the student select a biography at his reading level
• C. The librarian directs the student to a database that will quickly provide a list of resources and articles pertaining to Thomas Jefferson
• D. The librarian searches her computerized records, decides that none of the biographies in her school library are appropriate for this student, and initiates an inter-library loan. The borrowed biography will take about two weeks to arrive

Correct answer: B

Rationale: The librarian's best course of action in this situation is to direct the student to the biography section of the library because the assignment specifically requires the student to read a biography. By helping the student select a biography at his reading level, the librarian ensures that the student is staying on task and fulfilling the assignment requirements. This approach also encourages the student to engage with physical books rather than relying solely on the Internet for research. Choice A is incorrect because it deviates from the assignment's requirement of reading a biography. Choice C is not the best option as it overlooks the specificity of the assignment and may lead the student away from the required task. Choice D is not ideal as it involves a lengthy process of inter-library loan which may not be necessary if suitable biographies are available in the library.

2. What role do the spiracles play in the respiration of the insects described in the passage?

• A. They allow insects to breathe atmospheric air even when submerged.
• B. They protect the insect's internal organs from water pressure.
• C. They filter oxygen from the water for underwater breathing.
• D. They are used to expel carbon dioxide from the body.

Correct answer: A

Rationale: The spiracles in insects serve the crucial function of allowing them to breathe atmospheric air even when submerged. The passage explains that insects have a system of branching air-tubes that carry atmospheric air with oxygen to all tissues. The air enters these tubes through paired air-holes or spiracles, enabling insects to respire even when they are underwater. Choices B, C, and D are incorrect because the spiracles do not protect internal organs from water pressure, filter oxygen from water for underwater breathing, or expel carbon dioxide from the body. The primary role of spiracles is to facilitate respiration by allowing insects to access atmospheric air.

3. What is the purpose of the first paragraph in relation to the second paragraph?

• A. The first paragraph serves as a cause and the second paragraph serves as an effect.
• B. The first paragraph serves as a contrast to the second.
• C. The first paragraph is a description for the argument in the second paragraph.
• D. The first and second paragraphs are merely presented in a sequence.

Correct answer: A

Rationale: The first paragraph introduces the general characteristics of insects and their ability to live both on land and in the air, setting the stage for discussing specific examples in the second paragraph. The second paragraph then delves into examples of insects that transition from living underwater to the aerial phase, establishing a cause-and-effect relationship between the general concept introduced in the first paragraph and the specific examples in the second paragraph. Choice A is correct because the first paragraph gives the cause (insects being creatures of land and air) and the second paragraph provides the effect (specific examples of insects transitioning between water and air). Choices B, C, and D are incorrect because they do not accurately describe the relationship between the two paragraphs as cause and effect.

4. The speaker addresses his audience as 'My Good Friends.' What kind of credibility does this salutation give to the speaker?

• A. The speaker is an employer addressing his employees, so the salutation is a way to bridge the gap between himself and his employees.
• B. The speaker's salutation is one from an entertainer to his audience, using friendly language to connect before a serious speech.
• C. The salutation gives the serious speech that follows a somber tone, as it is used ironically.
• D. The speech is one from a politician to the public, so the salutation is used to grab the audience's attention.

Correct answer: B

Rationale: The speaker's address of 'My Good Friends' implies a sense of warmth and familiarity, indicating that the speaker wants to establish a connection with the audience before delivering a serious speech. This type of salutation is often used by entertainers to engage the audience and create a friendly atmosphere conducive to effective communication. Choice A is incorrect because there is no indication of an employer-employee relationship. Choice C is incorrect as there is no indication of irony in the salutation. Choice D is incorrect as the salutation aims to create a connection rather than grab attention as a politician might.

5. What does the following sentence most nearly mean? The preparatory instars of such insects are aquatic; the adult instar is aerial.

• A. The volume of water is necessary to prepare the insect for transition rather than the volume of the air.
• B. The abdomen of the insect is shaped like a star in the water as well as in the air.
• C. The stage of preparation in between molting occurs in the water, while the final stage is in the air.
• D. These insects first breathe in the water through gills, but then use the same organs to breathe in the air.

Correct answer: C

Rationale: The sentence is describing the life cycle of certain insects where their preparatory instars occur in the water, while the adult instar lives in the air. This means that the stage of preparation between molting or shedding of the exoskeleton happens in the water, but the final stage as adults is in the air. Choice A is incorrect as it misinterprets the meaning of the aquatic and aerial environments for the insect's life stages. Choice B is incorrect as it introduces a concept of the insect's abdomen being shaped like a star, which is not mentioned or relevant to the sentence. Choice D is incorrect as it introduces information about the insects' breathing organs, which is not directly related to the sentence's meaning about their life stages.
