Text: i don't i don't want to mess with it because since i don't know exactly all the ratios you know and everything that all the proportions the fuel and air and compression and all that stuff that needs to be precise and it's controlled by computer i figure i won't mess with that
Entailment: I will not change any of the ratios, since I don't know much about them.
Contradiction: I want to be able to tweak all the ratios manually.
