Can I please get some help on this question? There is no further information. Thank you.

A bank can make one of two types of loans. It can loan money to local rms, and have a 75% probability of earning $400 million and a 25% probability of earning $320 million. Alternatively, it can loan money to oil speculators, and have a 25% probability of earning $1,600 million and a 75% probability of losing $640 million (due to loan defaults by the speculators). Sarah, the manager of the bank, makes the lending decisions, and receives 2% of the bank's earnings. She believes that if the bank loses money, she can walk away from her job without repercussions, although she will not receive any compensation. Sarah and the bank's shareholders are risk neutral. How does Sarah invest the bank's money if all she cares about is maximizing her personal expected earnings? How would the stockholders prefer that Sarah invest the bank's money? Sarah will loan the bank's money to E and stockholders will prefer Sarah loan the bank's money to E
