Answer:
If you want to advocate for an issue, you can use both spoken and written language, in a way that is persuasive.
Step-by-step explanation:
This can be done in several ways. You can turn to more emotional techniques, or you can use arguments and reason, or even both. For spoken language, it is probably better to use more of the first, while for written language it is probably better to use more arguments and more evidence, since the nature of communication changes depending on the type of language that is used.
