Many corporations have started with a trend to hang motivational posters on their walls so as to keep their employees boosted. However employees are usually boosted and motivated by themselves due to the flaring incentives and promotions awaiting them so as to keep them motivated to increase their productivity.

D. does not adequately address the possibility that employee productivity is strongly affected by factors other than employees' motivation to work productively
E. fails to consider that even if employees are already motivated to work productively, motivational posters may increase that motivation
