answer: Maria asks Mr. Crandall to let her make major changes for the project. He agrees but if it doesn't work, Maria needs to re-do it.
documents: #Person1#: Mr. Crandall, I ' m sorry, but I really don ' t see the value in doing this entire project over from scratch. It would take a lot of work.
  #Person2#: That ' s certainly true. But, that ' s what this job is all about, Maria. There's no doubt that this project is unacceptable.
  #Person1#: I agree. But I think that we can handle the problem by making a few major changes. I ' d appreciate it if you would give me a chance.
  #Person2#: All right, Maria. I ' ll give you until tomorrow at 4:00 to produce a satisfactory piece of work, but otherwise, you ' ll have to re-do it.
