Answer:
The correct answer is Solitude is an inner concept rather than an outward one.
Explanation:
For a topic sentence, or the beginning sentence that signifies the main idea of the paragraph, you could focus on the fact that there are a variety of things to do at the beach (perhaps the 3rd sentence). To create a hook, or an eye-catching sentence, you can use the childhood memory of learning to swim, but perhaps in more detail. In other words, recreate the scene rather than just saying it was a happy memory (i.e. I'm five years old and am amazed by how weightless I feel in the water). Once you create the hook and topic sentence, you can talk about other activities at the beach as your supporting evidence.
