The final challenge is a ranking test involving five olive oils that vary in bitterness. The author finds this difficult since none of the oils seem particularly bitter to her. While others around her make exaggerated tasting noises to enhance the flavors, she struggles to keep up with the test, resorting to a comical attempt to aerate the oils with her tongue, but it yields no results.

Eventually, she makes the decision to abandon her overachieving tendencies and simply guesses the ranking. Her choice is influenced by her body's reaction to the large amount of pure olive oil she's consuming, signaling that her stomach can no longer handle the challenge. This moment highlights her vulnerability and willingness to let go of perfection.
