The Mower<br>Josh was mowing his yard. It had just rained recently. The ground was still a little soft. The lawnmower started to slow down. Josh realized the mower was stuck in the mud.
The lawnmower got dirty due to the mud
Despite the lawnmower being stuck in the mud there is no indication that the lawnmower itself is dirty therefore neither definitely correct nor definitely incorrect
