Truly inspiring work here, J.Y.! I'm hoping to follow in your footsteps on my next exam, wish me luck!

@coltonvida late response to this, but I understand it as "likely false" being equivalent to "undermined" because if the hypothesis is undermined by some piece of evidence, then that would lead to the hypothesis being more likely to be false, though it's fair to say that this line of reasoning isn't very straightforward.
