Answer with Explanation:
The context of communication adds value in the communication as now the listener would be more engaged and attentive to what the person is conveying in his message. It also helps listener to interpret communication.
- Something might be funny in one culture and not in another. This means if you are adding something that is culturally correct then it is more probable that the message conveyed was effective. Hence contexts must be according to the culture, norms, stories of people whom they know, etc. Hence cultural differences are of immense importance when we are setting up contexts for our communication.
- Level of Formality. The communication must be as per the occasion and level of formality of the occasion. In simple words, I would say that "When in Rome, do as the Romans do". If you are in a Formal occasion then your presentation must reflect use of formal language and when you aren't attending a formal occasions then you must be very relaxed and easy with the people (Usually friends) and of-course the dressing would be very casual.
