A Brilliant Designer of Computer Programs, Darren Has Often Been

A brilliant designer of computer programs, Darren has often been compared to the late Apple Computers cofounder Steve Jobs not only because of his abilities in the digital realm, but also his charisma. Like Jobs, he is not a lone techie writing code in a windowless room; he serves in an executive role at DiaTech, the company he and his partners founded. But now he has a problem: there is a special project for which he needs the help of a few key subordinates. They will need to work extra hours, and because of the top-secret nature of his new design, they will need to keep the nature of their work to themselves. The best way for Darren to get these employees on board for the project is to tell each one of them that

A) working on this project may give them an opportunity to learn about the skills that helped create the company.
B) as the founder and one of the leading executives in the company, he has the power to demand their compliance.
C) they will get extra pay above their ordinary salary, as well as a strong recommendation for advancement in the company.
D) after the project is over, he will take them to lunch and give them a one-hour career planning and question and answer session.
E) he does, after all, have the power and the means to make life very difficult for them if they do not offer him their absolute loyalty.
