Answer:
Simile and Personification
Explanation:
A <em>simile </em>is when you compare two things using the words like or as.
"The sun was like a staring eye."
A <em>personification </em>is when you give human characteristics to an inanimate object, or an object that wouldn't otherwise have those traits.
"It glared down at Hector in disaproval."
The sun can't physically glare at someone.
Even though Swift is not suggesting that the rich people in Ireland start eating the babies of the poor, he is still suggesting some realistic solutions. Most of all he is pointing out that the rich need to start doing something to balance out the economy and support the lower classes, instead of treating them like cattle. Comparing them to cattle by suggesting they eat babies points out this flaw of society and that it needs to be changed.
