Answer:
I and III: Simile and sensory imagery
Explanation:
Simile and imagery are both figurative languages that are used to make the writing more memorable and significant. While similes are used to compare two or more elements using the word "like" or "as", imagery is a vivid, descriptive and sensory language that is used to appeal to our senses of sight, hearing, smell, taste or touch.
The excerpt uses both techniques as it describes the way someone was wrapped by making a comparison: "like garbage sitting", and the subsequent words are descriptive enough to appeal to our senses of smell and sight: "by the smell of too old potato peels."
