"The Surgeon General warns smoking can adversely affect your health”
Logos or pathos or ethos

Ethos

Explanation:

Logos = Logic

The use of a logical argument

Pathos = Passion

The use of emotional appeal

Ethos = Ethics

The use of credibility and trust

As this statement mentions that the information came from a trusted source, the Surgeon General, this would go along with the Ethos appeal.

(you didn't attach a copy of the poem, but i'm answering as best as i can)

since a simile compares two unlike things using like or as, it kind of gives an item the ability to do something it can't.

example: "the player was like a tiger on the field"

in this sentence, the simile conveys the idea that the player was fast and strong, like a tiger.
