Dichotomous Keys-Practice with Shoes

Hello, I felt the need to practice with my shoes prior to moving onto the plants.   According to the History of Shoes-World Famous Inventors and Inventions, Lyman Reed Blake, an American inventor, invented a sewing machine to sew the modern soles of shoes.   For purposes of my practice here, we shall give him credit for developing the American modern shoe sole.   Let’s see if I have a decent understanding?   Thanks for any input.
NOTE: the #1 after the letter signifies prime.

  1. Looks good Marcia. Well done. You can use D’ to signify prime for D or any other letter. It sometimes is helpful to indent each statement.

    A. With laces
    …..B. with heels
    …..B’. lacking heels
    ………C. black
    ………C’. brown
    A’ lacking laces
    …………….D. Nike brand
    ………………..E. Black
    ………………..E’ White
    …………….D’. Other brands.

    It helps further organize your statements visually as well. I was not able to ident the text, so I used leading “.” to indent the text. Best, Steffi.
