帮忙分析一下下面的句子
How an 18-year-old girl has managed to figure out something that multi-national corporations have not has led to her being flooded with offers for her amazing leap forward.
另外附上词句的翻译：
一个18岁的女孩如何能想出这么多跨国公司都没想到的东西,她的神奇发明已经已经吸引了很多公司找上门.
主要是想请高人帮忙分析一下其中几个关键词的应用“HOW”,“have not”是不是修饰multi-national corporations?然后后面的“has led to her being flooded with offers for her amazing leap forward.”这句请帮忙仔细分析一下
