Will mark as brainliest if answered what does this mean? “i’d say it would be pretty hard to play soccer on the soccer field when it’s approximately twenty feet from where my sister was supposedly murdered.”

The key to the sentence is the word murder. Whoever was saying the sentence was trying to tell you that he or she had a sister who was murdered just 20 feet from the playing field. 

Twenty feet really isn't very much. Most small cars are just 4 feet shorter than 20 feet. That's not much. 

So whoever is saying this is saying that the wonders of playing soccer could not overcome the awful feeling he/she must have knowing that his sister died there. Every time the narrator got on the field, he would be reminded of her death.
