Evidence
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.
Conclusion
So the current president acted appropriately in the way in which she invited Dr. Hines.
Evaluate
The argument assumes that the examples are similar. Furthermore it assumes that previous club president acted appropriately in hiring the tax consultant.
