Check on interpretation

@Kyle that is correct and replacing the abstract language in the answer choices with what is actually taking place in the stimulus is a very helpful strategy on both Methods of Reasoning and Errors in Reasoning questions. You can break the stimulus down as follows: P: No one has been able to show that underinflation or overinflation of tires does not harm tire tread. C: Underinflation or overinflation of tires harms their tread. (D) states, "The argument rejects the possibility that what has not been proven (i.e. underinflation or overinflation of tires does not harm tire tread) is nevertheless true (i.e. underinflation or overinflation of tires does not harm their tread)." Hope this helps! Please let us know if you have any other questions.
