I made casual remarks to other runners that the shower was nice and they should try it also . I get the occasional laugh but I know they 're thinking to themselves " man this dude sweat A LOT " . I decided to take it easy from mile 4 - 7 so I would have some reserve for the negative split .

Q with options: Give answer the following question using evidence from the above passage: Why do n't the other runners say out loud that they think the man sweats a lot ?
Choose your answer from:
*They are secretly jealous and wish they knew how to sweat as much as him;
*They know that if they do n't alert him to the condition , they will win the race;
*To do so would be rude , and they are interested in being as polite as possible;
*None of the above choices .;
