Which medium would most likely use a conversational delivery tone?

a. a radio talk show about sports

b. a newspaper article on whale hunting

c. an nightly world news report on war

d. Internet coverage of a natural disaster

The correct answer would be a. Radio talk shows are usually more casual in hopes of being more appealing to listeners. Also, process of elimination would work well here because no station would ever use a casual tone of voice on horrific events such a natural disaster or war.
