    can you help me?
    If you post what you have this far, or at least a description of the steps how you would tackle it.
    I might be wrong.

    Thank you, anon. You sure know how to recognize different types of trees from quite a long way away.

    I think it would better benefit you if you did it on your own, rather than getting someone else to do it for you. It would certainly help when test time comes around.
