Final answer:
The poems 'The Man He Killed' and likely 'Sniper' use literary devices such as irony and symbolism to explore themes and deepen meaning. The irony is found in the juxtaposition of expectations versus reality, and symbolism uses objects or events to represent larger ideas. Option 4 is correct.
Step-by-step explanation:
When analyzing the poems 'The Man He Killed' by Thomas Hardy and 'Sniper' it's important to identify the literary devices used within them. Both utilize various techniques, though without the text of 'Sniper' it's challenging to pinpoint specifics.
Nonetheless, given the general knowledge of poetry, it's likely that these poems use devices such as irony and symbolism to convey deeper meanings. Irony involves using words or situations that seem to be the opposite of what one expects and is often present in poems that discuss war, such as 'The Man He Killed.'
Symbolism is using a person, place, thing, or event to represent something else, often seen in poetry to add a layer of meaning. Examples of these would be treating friends as foes due to war, representing the absurdity of conflict (irony), or the use of objects like weapons to symbolize broader ideas like violence or political conflict (symbolism).
