Denise, Solomon, Dolf, and Ziggy are teammates for their final project. To leave themselves ample time to produce a great final project, they meet weekly, discussing their progress toward final benchmarks and logic and design choices along the way. Everything seemed to be going well, until three days before the assignment is due, the team notices that Ziggy has not done any work. In a panic, the other members decide to finish his part. The presentation goes smoothly (Ziggy 'wings it,' but has excellent natural presentation abilities) the team - including Ziggy - receives an exemplary score. The book would describe Ziggy as a: a. Social loafer b. Social parasite c. Bad teammate d. Storming teammate
