How did the invention of the television change political communication?

Voters could evaluate candidates based on their appearance and demeanor.

Newspapers were no longer used to address political issues.

Candidates could not run for office unless they appeared on television.

Elected officials stopped making public appearances before live audiences

I believe the answer to this will be (A) Voters could evaluate candidates based on their appearance and demeanor.

This is because B doesn't make sense, newspapers still address political issues. I hardly think it was a requirement to be on television to run for office, so its not C. And like I said before, elected officials still make public appearnces before live audiences!
