Syntax helps the paper/story/paragraph/book flow properly. Without syntax, you're going to having this one big confusing mess that almost no one understands.
3rd one is the correct one
<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>
Monotone means having no expression in your voice, no anger, no happiness, no interest. This word would affect the tone by giving the reader the feeling that he just doesn't care about what is going on/ what he's talking about. I hope this helped!
