Answer
Brief Explanations:
To determine why Marley felt good about her campaign, we analyze each option:
- The first option about collecting books quickly doesn't directly relate to her feeling good about the campaign's purpose.
- The second option about discovering social media use is more about a skill, not the campaign's impact.
- The third option about reading diverse books is about her reading, not the campaign's outcome.
- The fourth option (selected) states she learned studies reflect her concerns, meaning her campaign's focus (her concerns) was validated, which would make her feel good about it.
Answer:
D. She learned that some studies reflect her concerns. (Note: Assuming the options are labeled A - D with the last as D; if original labels differ, adjust, but based on the selection, this is the correct reason.)
