Which sentence or phrase in the passage suggests an action of integrity? On Monday, Mr. Blackwell, the creative head of an advertising firm, instructed all his employees to make teams of two each and create a presentation for a new product by Friday. The best presentation would be selected to be pitched to a potential client. Derick and Sandra formed one such team. Derick worked on the content, while Sandra created the graphics for the presentation. On the other hand, their colleagues, Samantha and John formed a team of their own to work on the presentation. On Thursday evening, Samantha made a copy of the presentation and suggested John to pass it off as their work since it was far superior to the presentation that they had created. However, John maintained that they should not lie and take credit for it.
