The ability to give someone multiple modes of communicating a idea allows a person to be creative and able to express a idea how they believe it should be presented. This can also pose a problem because of miscommunication, for example in the supplemental text the news station wanted to be able to inform not only normal people but the deaf of a emergency. But the way they chose to present the information lead to frustration, and confusion because the translator that was chosen could not communicate the correct message.
