I would suggest switching "a lot" with "many". The word "many" gives a bit more with the professional flair. This is just my suggestion. It helps with the overall attitude, but it's fine if you want to keep it how it is. :)
The figure of speech used in the sentence above is:
<span>A. hyperbole
</span>
Hyperbole is one of the figures of speech used as a literary device to convey multiple meanings of words or phrases in a sentence and express it in an artistic manner to persuade readers. It uses exaggerated words and expressions (in this case, a hundred times).
