they were to develop a classification hierarchy of shoes, beginning with the shoe "kingdom" and becoming more and more specific, just like scientists did for the classification of living things. ) Which classification system of the shoes would BEST represent today's classification system of living things?
A) kingdom: shoe - phylum: Converse- class: tie or no tie - order: high top or low top - family: by color
B) kingdom: shoe - class: sneaker - phylum: tie or no tie - family: high top or low top - genus: by color
C) kingdom: shoe - family: Converse - order: high top or low top - phylum: tie or no tie - genus: by color
D) kingdom: shoe - phylum: color - class: tie or no tie - order: high top or low top - genus: pattern or no pattern
