Answer:
doesn’t make sense
Explanation:
the sentence doesn’t make sense. ♀️
Answer:
Very important. Each paragraph should begin with a topic sentence setting out what will be discussed. The body should contain properly structured sentences (no fragments or runons) containing supporting details—examples, explanations, or events. The concluding sentence should indicate in some way that the topic is completed or hint at the topic of the following paragraph. The writing should be concise but meaningful using well chosen words and avoiding repetition (except for rhetorical effect). Avoid bland words and cliches, and look for verbs that convey two ideas (such as paced for walked nervously) and replace it and they with the names of things.

Hope this helps.
a. three major supporting details.
There are three supporting details for the main idea on the theories to explain why people yawn. Each of the supporting details contains a key word or phrase to indicate that they indeed are a main supporting detail. These key words and phrases are "One explanation is...", "A second theory...", and "Yet another explanation...". These all show the supporting detail is contained in the sentence. The last sentences just build and connect to information that has already been introduced.
