| | A) | KNM-WT 15000 has a broad hip region and a barrel shaped chest |
| | B) | Lucy has a narrow pelvis and cone shaped rib cage |
| | C) | Lucy has a broad pelvis and a barrel shaped chest |
| | D) | KNM-WT 15000 has a narrow hip region and a cone shaped chest |
| | E) | KNM-WT 15000 has a narrow hip region and a barrel shaped chest |

An examination of human variability demonstrates that different body types are adapted to different environments. How does the skeleton of KNM-WT 15000 demonstrate this principle? |

| | B) | it is adapted for tree climbing |
| | C) | it is adapted to the cold |
| | D) | it is long and linear |
| | E) | it lacks a tail |

KNM-WT 15000 has been suggested to be an eleven to twelve year old boy who stood 5’3”. It has been estimated that this boy would have eventually reached six feet tall. What is the significance of this determination? |
| | A) | indicates increased sexual dimorphism |
| | B) | represents a modern growth trajectory |
| | C) | suggests increased nutritional intake |
| | D) | indicates lack of competition for resources |
| | E) | suggests the presence of a colder climate |
