【问题】Who did Edison raise money for?
 新闻首句原则,了解大致内容是Edison卖柠檬水和画画为生病需要做心脏手术(surgery)的弟弟筹资。第一道题给考生来了个下马威,难度系数比较高, 需要考生自己分类信息再听取问题作答,这种题型称为模棱两可型题目,考察学生听力和反应能力。A) Her friend Erika. 根据顺序原则,A选项在新闻最后才出现且与问题不符，先不作考虑。C/D选项是Edison祖母猜测Edison偷听到祖父的对话,从而得知弟弟生病,与问题无关,故排除。
原文：
A 9-year-old girl in New Mexico has raised more than $500 for her little brother who needs heart surgery in Houston Texas this July. Addison Witulski's grandmother Kim Allred said Addison probably overheard a conversation between family members talking about the funds needed to get her little brother to treatment.
" I guess she overheard her grandfather and me talking about how we’re worried about how we’re going to get to Houston, for my grandson’s heart surgery,” said Allred. She decided to go outside and have a lemonade stand and make some drawings and pictures and sell them.”
That’s when Addison and her friends Erika and Emily Borden decided to sell lemonade for 50 cents a cup and sell pictures for 25 cents each.
Before Allred knew it, New Mexico State Police Officers were among the many, stopping by helping them reach a total of $568. The family turned to social media expressing their gratitude saying, “From the bottom of our hearts, we would like to deeply thank each and every person that stopped by!”
