Question

\cleaning your room will be a herculean task\ is an example of what type of figurative language?
simile
metaphor
idiom
personification
allusion
rewatch

Explanation:

The term "Herculean" references Hercules, a figure from Greek mythology known for his extremely difficult, strength-demanding labors. An allusion is a figurative language device that indirectly references a well-known person, story, or work. This phrase does not use "like" or "as" (ruling out simile), does not directly equate two unrelated things (ruling out metaphor), is not a fixed figurative phrase (ruling out idiom), and does not give human traits to non-humans (ruling out personification).

Answer:

allusion
