What characteristics of "Lord Randall," "Get Up and Bar the Door," and "Edward Edward" show that they were intended to appeal to a general audience rather than an elite audience?

These ballads include the repetitions of words and verses that are typical of folk-songs and folk poetry in general. This is probably the most obvious thing that indicates they are part of a tradition of popular art, having its origin and appeal among ordinary people and not with royalty or the upper classes overall.

well seeing i am an artist and i actually did a self portrait; i will describe how i painted it.   i used acrylic on a stretch canvas about 4 feet wide by 6 feet tall. i painted myself smiling in a soft pink long dress, white tile floor sitting on a white couch with a table behind and a vase of gorgeous flowers.   i also had a round white hat with a soft pink ribbon through it laying on the floor and on the table behind me was a lit candle. i kept it simple but soft and romantic.
