Is there a way someone can unblur this?

you might be able to go on a editor like pics art and filter clean it

Explanation:

Did you find it blurred, or did you blur it? You cannot unblur an already blurred image, but you can reverse a blur you made. You can go on an editor program and fix it there.

I hope I helped... :)

the following key ideas correctly express the key sentence.

restate key idea: most people can learn to swim in ten short lessons.

restate key idea: the majority of water-accident victims require mouth-to-mouth breathing.

restate key idea: an empty, tightly closed gallon jug will support a tired swimmer.  

restate key idea: first aid is to prevent accidents as well as assist in rescue.

explanation: the key idea needs to have the same topic as the key sentence (drowning and safety).
