Option 2: "To keep it dry."
Explanation: This option is correct as the text explicitly states that the nest is built high above the water to keep it dry. This aligns directly with the main idea of the text regarding the nesting behavior of the Trumpeter Swan.
Option 1: "To make it visible to other swans."
Explanation: This option is incorrect because the text does not mention visibility as a reason for the nest's height. The primary focus is on keeping the nest dry, not on making it visible to other swans.
Option 3: "To attract more signets."
Explanation: This option is incorrect because the text does not suggest that the height of the nest is intended to attract more signets. Instead, it focuses on the protection and care of the signets after they hatch.
Option 4: "To make it easier for the swans to find food."
Explanation: This option is incorrect as the text does not indicate that the height of the nest aids in finding food. The swans search for food underwater, which is unrelated to the nest's height.
