1. Why do some insects have a life cycle divided between water and air?

• A. To highlight the adaptability of these insects.
• B. To illustrate the different environmental challenges they face.
• C. To describe the process of metamorphosis in these insects.
• D. To show the evolutionary advantages of such a life cycle.

Correct answer: D

Rationale: The correct answer is D because the life cycle of insects is divided between water and air to demonstrate the evolutionary advantages of this adaptation. Insects have evolved to inhabit both aquatic and aerial environments, allowing them to thrive in diverse conditions. Choice A is incorrect because the division between water and air in the life cycle does not solely highlight adaptability but also evolutionary strategies. Choice B is incorrect because the question focuses on the reason for the specific division in the life cycle, not on environmental challenges. Choice C is incorrect because while metamorphosis is part of the life cycle, it does not directly explain why it is divided between water and air.

2. Which of the following is the meaning of the word bestowed as it is used in the passage?

• A. purchased
• B. forgotten
• C. accepted
• D. given

Correct answer: D

Rationale: The word 'bestowed' in this context means to be given or presented with something. In the passage, it is mentioned that good powers were bestowed upon different animals by Epimetheus. This implies that these powers were given or presented to the animals. Choice A, 'purchased,' does not align with the context of the passage as the animals did not buy or acquire these powers. Choice B, 'forgotten,' is incorrect as it does not relate to the act of giving. Choice C, 'accepted,' is also incorrect as it implies that the animals willingly received these powers, which is not the case in the passage. Therefore, the correct answer is 'D: given.'

3. When evaluating the credibility of research sources, which of the following is a valid consideration?

• A. It is credible if published in a peer-reviewed scholarly journal.
• B. It is never credible if it is a source published online.
• C. It is not necessarily more credible based on author affiliations.
• D. The number of times a source is cited does not affect its credibility.

Correct answer: A

Rationale: The correct answer is A. It is credible if published in a peer-reviewed scholarly journal because peer review ensures that the research has been evaluated by experts in the field for quality and accuracy before publication. This process enhances the credibility of the research source. Choice B is incorrect because not all online sources are unreliable; credibility depends on various factors beyond the publication medium. Choice C is incorrect because author affiliations can indeed impact credibility, but they are not the sole determinant. Choice D is incorrect as the frequency of citations can indicate the impact of a source but does not guarantee its credibility.

4. What would a mongoose likely eat according to the food chain diagram?

• A. Shrub
• B. Aardvark
• C. Vulture
• D. Mouse

Correct answer: D

Rationale: According to the food chain diagram, mongooses are consumers that feed on smaller animals like mice, making choice D the correct answer. Shrub (choice A) is a plant and not a typical food for mongooses. Aardvark (choice B) is a large mammal that is not a primary food source for mongooses. Vulture (choice C) is a scavenger bird that typically feeds on carrion, not a preferred food for mongooses.

5. 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.
