Question

if practice makes perfect, and no one is perfect, then why practice?
○ rhetorical question
○ irony
○ paradox
○ chiasmus

Explanation:

A paradox presents a seemingly contradictory statement or situation that may reveal a hidden truth. The statement here sets up two premises ("practice makes perfect" and "no one is perfect") that appear to create a contradictory logical conflict about the purpose of practice, which fits the definition of a paradox. A rhetorical question is one not seeking an answer, but this is framed as a logical contradiction. Irony involves a contrast between expectation and reality, and chiasmus is a reversal of grammatical structures, neither of which apply here.

Answer:

Paradox
