A sneeze is a sudden explosion of air from your nose and mouth. You usually sneeze if something tickles the inside of your nose, or if you have a cold.
It is a good idea to cover your nose and mouth when you sneeze, like the man in the picture. A lot of mucous can come out when you sneeze and can travel a long way. If you are sick, you can make other people sick by sneezing near them.

You solve a puzzle or a problem when you work out an answer or solution. For example, you solve a jigsaw puzzle when you put all the pieces together to make a picture, and you solve a Rubik's cube when you have each face of the cube a single color.
You spill something when you accidentally remove it from whatever it was supposed to be inside.
The picture is of some spilled wine.
