Preston has limited range of motion in his arms and is not able to throw far but would like to join kickball game. what accommodation can they make to him fully participate?

What can be made for him to be able to play fully is they could give him a role in the game where he wouldn't have to do this at all, or they all would play in a handicapped way which would make him more equal to his co-players. 

You did not show us the image of the burger, but i shall try to answer as best i can.  when purchasing food, always consider the ingredients as well as the person who prepared it. consider if they were hygienic people or not, in case the burger was infected with bacteria. no mortal should place an infected burger into their mouth.
