Question

it took a million years for thomas to finish his homework and turn it in to his teacher. - this is an example of
simile
onomatopoeia
hyperbole
personification

Explanation:

The sentence "It took a million years for Thomas to finish his homework and turn it in to his teacher" uses an exaggerated time ("a million years") to emphasize how long the homework took, which is the definition of hyperbole. Simile uses "like" or "as", onomatopoeia is a word imitating a sound, and personification gives human traits to non - human things; none of these apply here.

Answer:

Hyperbole
