Some members have criticized the club' s president for inviting Dr. Hines to speak at the annual awards banquet without consulting other club members beforehand. But a few years ago the previous club president hired a tax accountant even though he had not discussed it with club members beforehand. So the current president acted appropriately in the way in which she invited Dr. Hines. Which one of the following is an assumption on which the argument relies? ["The club's previous president acted appropriately in hiring the tax accountant without first consulting other club members.", 'At the time the previous club president hired the tax accountant, most club members did not expect to be consulted about such matters.', 'The previous club president had also invited speakers without first consulting other club members.', "Dr. Hines accepted the president's invitation to speak at the club's annual awards banquet."]
