To develop a clear sense of audience, a writer should consider?

Question

the reader's interest and knowledge.

the reader's education, age, and gender.

the reader's existing ideas and opinions.

all of the above.

Answer 1

I say all of the above. If you are speaking...you don't want to refer to Hannah Montana if you are speaking to a college age audience, which covers all areas....no matter your discussion.  

Answer 2

If I were a writer I would consider all of the above. They all take into account the different types of things that would interest them into buying/reading your book, especially age, education, and interest.

Different subjects excite different people. Age is a key factor because people do not instantly know what certain words mean and there are simply things that different people do not want to read about once they are adults. If you write a children's book education should be considered because they are not quite advanced yet. That is why there are different "reading levels."

Answer 3

it's all of the above
