Rationale: Given Gemma's goal of seeing as much as possible in a short time while enjoying outdoor activities and nature, the best travel guide for her would be 'Exploring the Hawaiian Islands: The Best Waterfalls on the Big Island and Maui.' This guide aligns with her interest in outdoor activities and waterfalls, making it the ideal choice to enhance her trip experience. Choice B, 'Na Pali: The Two-Day Hike That Changes Everything,' focuses on a specific hike and may not cover a broad range of attractions Gemma wants to explore. Choice C, 'Pineapples, Taro, and Roasted Pigs: A Dining Guide to Hawaii,' is more food-oriented and doesn't cater to Gemma's interest in outdoor activities. Choice D, 'The Top Ten: Beaches, Restaurants, and Sightseeing in Honolulu and on Oahu,' while offering a variety of attractions, doesn't specifically target Gemma's interest in exploring waterfalls and the natural beauty of Hawaii as she desires.

Correct Answer: C

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.

Correct Answer: B

Rationale: Chapter II typically focuses on baking and sweet treats, which would likely include recipes for banana bread and blueberry muffins. Sarah should consult this chapter for vegan-friendly versions of these recipes that will cater to her strict vegan guests. Choice A, Chapter I, primarily covers yeast breads, not the specific recipes Sarah is looking for. Choice C, Chapter IV, focuses on elegant, easy entrees, which are not relevant to the sweet treats Sarah wants. Choice D, Chapter V, covers delicious desserts and drinks, but it does not specifically mention the items Sarah is interested in, making it less likely to contain the recipes she needs.

Correct Answer: C

Rationale: Sarah wants to offer her vegan guests a slightly more filling option such as a light soup with some biscuits. Chapter II of the cookbook covers light soups, making it a suitable choice for soup ideas. Chapter IV focuses on baking and bread recipes, including biscuits. By consulting Chapter II for soup recipes and Chapter IV for biscuit recipes, Sarah can find appropriate dishes for her vegan guests. Choice A (Chapter II and Chapter III) is incorrect because Chapter III does not cover biscuits. Choice B (Chapter I and Chapter III) is incorrect as biscuits are not part of Chapter I. Choice D (Chapter V and Chapter VI) is incorrect because these chapters do not contain relevant recipes for a light soup with biscuits.
