The EPA Is Considering Two Different Sticker Designs for Auto

The EPA is considering two different sticker designs for auto fuel economy. One design included a letter grade A+ to D, but a few members argued that the letter grade fell short because it is imbued with memories people have of school. Some others argued that it was simple and easy to understand. The result was that neither of the parties tried to understand what the other was saying. This scenario best exemplifies the organizational barrier of:

A) semantics.
B) information overload.
C) status difference.
D) different perceptions.
E) conflicting signals.
