Inference: an inference is an educated guess based on evidence.
"Young Brown dashed to the crime scene as soon as he was called. He got to Cafe 5, the crime scene, and found the police gathered around the victim."
I can infer that Young Brown had something to do with the crime or the crime effected someone he/she loved.
"They all comforted me for a while, till the elevator opened and I saw my mom on a big long stretcher." "The doctor hadn't come out of her room yet."
I can infer that her mom is going to die or has already died.
"Competitive cheer leading is a sport. It is a physical activity that is governed by rules under which a winner can be declared and its primary purpose is to compare the skills of participants. Hopefully, cheer leading will become as well-known a sport as football and basketball, and even appear in the Olympics since cheerleaders are just as athletic and physically fit as those involved in the more accepted sports."
I can infer that the person who wrote this is in cheer leading because she didn't talk about why cheer shouldn't be considered a sport.
