John Orbell and his colleagues (1988) studied social dilemmas by putting people into groups,then giving each person money to keep or to donate to the group at a higher return rate.The catch was,of course,that if only one or a few participants donated their money,they would lose on their investment.The researchers found that when group members were not allowed to discuss their plans,they typically

A) kept all the money they were given for themselves.
B) donated a little money to the group, but kept most of the money for themselves.
C) donated all of their money to the group.
D) split the money evenly between themselves and the group.
E) donated most of their money to the group, but kept a little money for themselves.
