Answer:
C. To fully understand a speech, it's only necessary to know the words of the speech
Step-by-step explanation:
If you don't know the context in which a speech is given, then you cannot fully understand what is being spoken. Without context, the speech could be interpreted in several different ways based on who is reading it and when!
Without context, it becomes anything the reader interprets it to be.
However, with context, it becomes what the writer wants the reader to interpret it to be.
