Question

Which statements about Plains Indian clothing are true? Choose all answers that are correct. A. It was made of cloth woven from sheep's wool or cloth acquired through trade with settlers. B. It was decorated with porcupine quills, glass beads, and hair. C. It was decorated with the same designs in each Plains tribe. D. It was designed using glass beads that were acquired through trade with settlers.

Answer 1

C is not correct. The designs usually represented family history.
A is not correct either. The base was usually elk and deer and a robe of buffalo fur in the winter.
D is actually an explanation for D. 
B is probably the answer (another reason for hating multiple guess) although you have to know D in order to pick B. Hair was an acceptable decoration.
