(A) Some people employed in the computer industry change jobs if they become bored with their current projects.

(C) Many of Summit’s senior employees had previously worked at only one other computer company. (D) In a nonhierarchical work environment, people avoid behavior that might threaten group harmony and thus avoid discussing with their colleagues any dissatisfaction they might have with their jobs.
(E) The cost of living near Summit is relatively low compared to areas in which some other computer companies are located.
