First Human Source Name and Position:

what do they mean by this ?

What might be a HUMAN source as opposed to a printed source?

the internet ??idk

No! A human being. An expert on the subject the journalist has interviewed in person, in real time. You identify the source by name and his/her position, as in the county prosecutor or the city's environment department head, etc.

The interview can be face to face or by telephone, or even via e-mail.

The source might also be a written statement from the human source, as in:

"Ottawa County Sheriff Mary Jones said in a written statement that she is 'pursuing all clues to the murder.'"

In any case, a human source must be identified by name and position.

i think i get it now somebody that's involved in the story that the journilist interveiw like if there was a story on a little boy with a condition the human source would be there parent because you would interveiw them about the child ?

okay so i know her position would be a sheriff and her name mary jones i get it

Yes, or a medical expert who can explain the condition, or anyone who can provide expertise on the topic. Identify the person my name and position. " Johnny's mother says..." Or, "Dr. Theodore McNutt, professor at the Hope College School of Medicine..."

former professional American football running back John Cappelletti spoke to the dancers about losing his brother, Joey, to leukemia ten years earlier, and the event that year raised more than $95,000 ?? is this a good one

Well, more or less, yes. Identifying the football player as such establishes his celebrity. The fact that his brother died of leukemia establishes his "bona fides" to talk about the issue. You need to have identified the event, too. I'm GUESSING it was a fund raiser for leukemia research and not stray pets or something else?
