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 .
According to the above context, choose the best option to answer the following question.
Question: Why do n't the other runners say out loud that they think the man sweats a lot ?
Options:
- 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 .
