How does the author use tone throughout Exploring the Titanic to help the reader understand the text?

to express the author’s story and add emotion to the events
to reveal the strong attachment that the author has to the ocean
to help the reader know exactly how the Titanic was discovered
to encourage the reader to become an ocean explorer also

the answer is A

Explanation: To express the author's story and add emotion to the events.

both the address and the poster use diction to convey their message. diction is defined as a style of writing or speaking based on the types of words chosen in order to send a message. parallelism is when a similar sentence structure is used for several sentences on a text; roosevelt's address doesn't follow that. repetition has to do with repeating a word or sentence in order to emphasize and idea, however neither the poster nor the address use repetion. finally, the address doesn't use images to convey a message.
