Knows little. 2 and 3 are both presuming too much, as it's the writer's duty to get them interested and informed. 4 basically doesn't matter, and furthermore may not even apply in many forms of writing. 1 is the best answer, as writing for general audiences is intended to inform and expand the horizons of the reader.
I believe the correct answer is: C. Using physical gestures to emphasize points
.
Using physical gestures to emphasize points is a rhetorical device is unique to speaking, as it cannot be perceived in the written text. On the other hand appealing to the audience’s sense of humor, creating a metaphor to interest the audience and organizing your thoughts into a logical pattern are devices used in both speaking and writing.
It's either A or D but most likely D hope that helps:)
The answer is c. hope this helps
