Read the text and answer the multiple-choice question by selecting the correct response. Only one response is correct.

The coastal wetlands have environmental and economic importance. Wetlands provide natural wealth. They have important filtering capabilities. As the run-off water passes, they retain excess nutrients and some pollutants. They maintain water flow during dry periods. Thousands of people depend on groundwater for drinking. They act as natural sponges of flood waters and contain soil erosion. They control floods and save the buildings from collapsing during heavy rains. The hardwood-riparian wetlands along the Mississippi River can store sixty days of floodwater.

Option 4: "The Ecological Functions and Economic Values of Coastal Wetlands"

Explanation: This option accurately reflects the main idea of the text, which discusses both the ecological functions, such as filtering capabilities and flood control, and the economic importance of coastal wetlands. It encompasses the various roles wetlands play, making it a suitable heading for the paragraph.

Option 1: "The Filtering Mechanism of Wetlands"

Explanation: While the text mentions the filtering capabilities of wetlands, this option is too narrow and focuses solely on one aspect of wetlands. The main idea of the text encompasses broader ecological functions and economic values, making this option incomplete.

Option 2: "Riparian Wetlands along the Mississippi"

Explanation: This option is incorrect because it only highlights a specific type of wetland and location, which does not capture the overall theme of the text. The text discusses coastal wetlands in general, not just riparian wetlands, thus failing to represent the full scope of the information provided.

Option 3: "Wetlands- A Great Source of Water during the Dry Summer Days"

Explanation: This option is misleading as it emphasizes only the water supply aspect of wetlands during dry periods. The text covers various ecological functions and economic benefits of wetlands, making this option too limited and not reflective of the comprehensive discussion in the paragraph.
