<span>For over two hundred years, the reason for New England's Dark Day was unknown.
This represents the main idea because it lets the reader know that the passage is talking about a "Dark Day", where it happened (New England), and the fact that for over two hundred years it was a mystery. It also gives an indication that the mystery will have been solved by the end of the passage. </span>
<span>At the beginning of the paragraph, the topic is about how volunteering is beneficial for one's general health as it may include minor-to-moderate physical activity and reduces chronic pain and heart disease symptoms. Then, it explains that not all voluntary work may fulfill this need due to their sedentary nature, and how such should be combined with actual physical activity. From there, the paragraph goes on to say which are examples of everyday activities that can be turned into exercise, which completely diverts from the original idea.
</span>Therefore, your best answer is <span><u>The paragraph contains sentences that wander from the main topic.</u></span>
