It is ment to persuade D. because they are giving you reasons why you should join the navy.
Dramatic Irony is when you try to do something but do the opposite
Situational irony is when the reader knows something that the character doesn't
And verbal irony is saying something but it means a totally different thing
The answer would have to be D, unchallenging due to its context. The author is describing a final word that is described as something that is obvious (the reader can’t ignore it).
Therefore, within that context, the adjective would have to be something that “grabs” the readers’ attention. That would obviously rule out commonplace, which, by name alone doesn’t catch you as something unable to ignore. Oddly that answers B and C are the same, but can also be ruled out quickly within context. “Comfort” also suggests that it is almost redundant, but certainly not something to keep an audiences’ attention.
The only answer, therefore, that answer that makes sense within context, as well as providing an eye-keeping ending for a conclusion paragraph would be unchallenging.
B seems most correct. Have a good day/night!
