Pants that you get from the store
The correct answer would be poetry
The technique that this sentence best illustrates is understatement.
Understatement means that you are not showing the full 'strength' of something, but it is rather understated - so here, the coach only said that 'he was glad' even though his team won the Super Bowl, which is a huge deal. So his emotions should have been way stronger.
Hopelessness and Death VS. Hope and Life is different because when you're hopeless death will strike quicker but with hope you could live longer. I hope this helps.
