answer: #Person2# is interested in the Petty Consumer Loan and asks Maria about the interest rates. Maria tells #Person2# that the rate is fixed by the PBC.
documents: #Person1#: Hello, this is IBA Bank. Maria speaking, how may I help?
  #Person2#: Hi, I'm looking into your loans and I'm a little confused about the interest rates. Could you give me some advice?
  #Person1#: Not a problem. Which loan was it you were interested in? Sorry, I must ask, because the interest rates can depend on the type of loan you apply for.
  #Person2#: I understand. I'm interested in the Petty Consumer Loan.
  #Person1#: One of our most popular! The usual interest rate is fixed by the PBC. That is The People's Bank of China. But of course, with some loans, credit rating and loan amount come into play, too.
  #Person2#: So, the rate could fluctuate a little, depending on the amount given by the PBC?
  #Person1#: That is correct.
  #Person2#: I'm going to have to do some more research into this. Thanks for your help, bye for now.
