A--You know the person (Henry) and the topic (paying for a movie ticket).
B--You know the people (the twins) and the topic (plans for their party).
D--You know the person (my mother) and the topic (lost an earring).
BUT for C there is a very vague sentence that makes you question: what is it that they wouldn't enjoy? So it is C.
The picture isn’t clear, what does it say
<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>
