Rationale: Source C provides the best material for the assignment because it emphasizes the importance of preserving wetlands, acknowledges the endangered status of wetlands, and suggests a solution involving private donors. The source highlights the crucial issue at hand - the disappearance of wetlands - and proposes a practical solution, making it a reliable and relevant source for an assignment on wetlands conservation. Choice A focuses more on the profit aspect rather than conservation. Choice B blames greedy businesses without offering a practical solution. Choice D discusses the relationship between businesses and wetlands but lacks a clear solution for conservation compared to Source C.

Rationale: The passage is structured in chronological order as it presents events in the order in which they occurred. It starts with Harriet Tubman's background as a slave, then progresses through her marriage, escape, and subsequent actions to help other slaves. Each event is presented in a time sequence, making it clear that the passage follows a timeline of events. Choices A, B, and D are incorrect because the passage does not focus on demonstrating cause and effect relationships, outlining problems and solutions, or comparing and contrasting different elements. Instead, it provides a historical account of Harriet Tubman's life in a sequential manner.

Choice A (200) is for Religion, not related to ancient Greek plays. Choice B (600) is for Technical and applied science, unrelated to literature. Choice C (700) is for Arts and recreation, more related to the performing arts but not specifically focused on written plays from ancient Greece.

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 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.
