Answer:
I believe your answer should be D, "by using evidence from someone who is an expert in a given area"
Hello. Your question is incomplete, so it is not possible to answer it accurately. However, I will try to help you in the best possible way.
It is only possible to know the theme and support details of your text by reading it. In this case, to answer this question, you must recognize the main theme of your text (which is the main message that the text wants to send). After recognizing the topic, it is possible to find the support details, because these details are additional information that explain or prove the main topic.
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.
