    If |Sp(G)| = 1, plz prove that G is a tree.
    where Sp(G) = {spanning trees of G}

    Please take no offence at this comment. But from the tenor of your general questions I have to wonder how careful you are in trying to ingest the meaning of the definitions on Graph Theory.
    Let me give you a website that may help you: Graph Theory.
    To you current question: If one edge is removed from a tree, is it still connected?
    What does it mean to span?
    What is a minimal span?

    Ok, I'm not sure about 'span', and why it's called 'spanning tree'. I just know its definition.
    Due to your questions,now I can answer my question.

    I'll try to 'ingest' definitions on Graph Theory.
