The statement that best describes the effect of rhythm is statement is the last statement. I say this because in the poem it says "In a field by the river my love and I did stand," to me that shows 2 people in love in a field by the river just standing there. The text also says "she bid me off easy... but I was young and foolish full of tears." That piece of text shows me that the girl in the relationship broke up with him and the boy was very sad.
