please help me out to answer those two questions thumps up later on.

1. There were a number of participants whose actions or behavior contributed to the financial crisis of 2008. Identify two of these group players and discuss their roles in precipitating the crisis.

2. Suppose you are negotiating a loan of $5,000 from your local bank. The bank has offered you a simple interest loan of $5,000 at an annual rate of 8 percent, or a discount loan at an annual rate of 7.5%. What are the available funds ($) and the effective rate (%) for each loan type? (Show your work.) Which loan offer would you take and why?
