Answer:
Simile
Step-by-step explanation:
"Like burnt-out candles alongside a sick man's bed" compares something to something else. Whatever it is, it is compared to torches that have burned out. "Like" was used to support the comparison. Its goal is to compare one or more qualities of a burnt-out flame to anything else. Using supporting words is termed simile. They are a fairly frequent figure of speech, like metaphors, except that metaphors do not include support words.
