In mentioning the ships in lines 18 - 19 (a heroic ... sails furled), the author uses the literary device known as ___ in order to convey ___

A paradox presents a statement that contradicts itself but may reveal a deeper truth. While the author may express longing in the text, the specific use of ships in these lines does not embody a contradiction that relates to climate. Thus, this choice does not accurately reflect the literary device or the conveyed meaning.

Hyperbole is an exaggerated claim not meant to be taken literally, often used for dramatic effect. However, the mention of ships in the context provided does not exaggerate the atmosphere of the African forests, but rather illustrates a more grounded portrayal of nobility, making this choice incorrect.

Simile involves comparing two different things using "like" or "as." The lines in question do not make a comparison to vegetation, nor do they focus on such features. Instead, they highlight the human-like qualities of the ships, thus this choice misrepresents both the literary device and its intended expression.
