Why does the narrator use her prize money to purchase the doll? 1. She wants to appear mature to mama.
2. She was to persuade pop to come home.
3. She wants to support Mr. Redmond’s business.
4. She wants to make her little sister happy.

4. She wants to make her little sister happy.

Explanation:

I am answering this to the best of my knowledge. This is because the excerpt you uploaded is not complete for an expert to see.

But Option 4 seems to be the correct answer. Since Elizabeth went straight to the doll, that shows she loves dolls and if she must be happy then the narrator must get the doll for her. So, I believe that the narrator can only use her prize money to purchase the doll for Elizabeth in order to make her happy. We can always sacrifice so much in order to make the people we love happy.

So, I believe that Option 4 is the correct answer.

  plan: i will begin with a quotation about the importance of unity in a community. then, i will state my claim that an activity will unite our school by creating a shared vision, purpose, and direction. in the body, i will use three main points that describe the different avenues the students can take: through a variety of clubs, through a special event, or through an awareness week. i will provide evidence about other towns that have unity activities and the kinds of events that they include. pictures will illustrate my three main points in action. for the ending, i will restate the main idea in a new way and pose a question to keep the audience thinking. 

the type of supporting detail is fact!
