Final answer:
The sentence functions as a 'hook' in an introductory paragraph, capturing the reader's interest and leading into the main content. It is different from a 'topic sentence' that usually starts body paragraphs by summarizing the main argument or point.
Step-by-step explanation:
The sentence in question serves as a hook, which is designed to capture the reader's attention and interest in the introductory paragraph. It does this by making an assertive statement about garlic, challenging those who might disagree, and hinting at evidence that may change their minds through recipes. This hook leads the readers into the topic, persuading them to read on for an illustration of the topic sentence's point, an explanation of the sentence's point, or evidence demonstrating the topic sentence's point. A topic sentence, on the other hand, generally comes after the hook and context/background information, and it broadly summarizes what the paragraph is going to be about, often indicating a transition from the previous content. It is the first sentence in the body paragraphs that presents and argues the main point.
