I'm practicing an English Language Analysis Essay (from VCAA 2014 English Exam) and the author of a response states:
But no, let's spend a few trillions more on the illusion that we can solve our problems by leaving Earth and finding somewhere better.
I have identified the sarcastic tone and the negative connotation of "illusion" but here's my question:
What is the persuasive technique used in "few trillions"? Describing a large object/amount in a small scale?
