Wool

 
The starting sample for each requirement is a lock of raw fleece.  Only fleece prepared for spinning by the applicant should be used.  A different wool breed must be used for each skein.  Include a fine wool, a carpet wool, a luster-type wool, etc.
I did well on this section.  Note:  While the COE handbook makes no mention of not using a fiber more than once, you probably shouldn't.  There was a comment regarding the fact I spun two skeins with navajo churro wool--1 in the equipment section and 1 here in the wool section. 
Frankly, the COE is a costly adventure.  It is wasteful to buy even a pound of wool  (let alone a whole fleece) of something that just isn't your "go to fiber"....and then only spin a one ounce skein of it.  Not that it wasn't nice wool because it really was.  I just normally don't go for the coarser end of the wool spectrum.
